In 2020, the options for crane wire ropes were limitless. Did you know The first successful stranded iron wire rope was developed in 1831–34 by Wilhelm Albert, a mining official of Clausthal in the Harz Mountains in Saxony? Consumers are getting a product from the best wire rope suppliers to suit their individual needs seamlessly. You will discover that there are many possibilities available when looking for wire ropes or rigging materials. Many people find it time-consuming and daunting to make their pick from the different types of wire ropes. However, how do you determine the best ropes for your industrial operations? Understanding the most popular wire rope types makes your investment worthwhile.

Delving deep into wire rope specifications

The number of wires used in each strand and the number of strands for the entire rope is commonly used to categorize wire rope specifications. The streamlined approach uses a pair of numerals, such as 7x19, to identify cable. The first number represents how many strands there are in a rope (in this case, seven strands are used). The second number indicates how much wire was used to create each strand (19 wires).

7x19 and 7x7 wire ropes

The construction crews use the 7x7 wire ropes to maneuver bulky objects and deal with towing. In addition, this rope is also used when moderate flexibility is essential. Typically, the 7x19 wire ropes are used in heavy applications. They are known for their withstanding capacity to handle a lot of stress before reaching their threshold. These ropes offer the most flexibility compared to the 7x7 or 1x19 types.

A 7X7 wire rope is built from 7 strands, each with 7 wires. This means a 7x19 variant comprises 7 strands with 19 wires, giving the rope total of 133 wires. When you do the calculation, a 7x19 cable has more than 2.5 times the number of wires in a 7x7 rope. Therefore, 7x19 wire ropes are usually the smart choice for the application that demands repeated and tight turns. On the other hand, 7x7 ropes are rigid, which makes them an excellent option for aircraft and automotive devices.

6x19 and 6x36 wire ropes

Classification ropes in the 6x19 size offer an excellent compromise between fatigue and wear resistance. With moderately sized sheaves and drums, they provide excellent service. Compared to 6x19 classification ropes, 6x36 classification ropes are less abrasion resistant but more flexible. There are numerous tiny diameter wires included in each strand. Flexibility increases with the number of wires. In comparison to IWRC, fiber core rope offers greater flexibility. Although the strength is less than IWRC, flexibility might be of paramount significance in some applications.

The 6 x 19 classification of wire ropes and 6 x 36 classification of wire rope's operating characteristics differ; all have a similar weight per foot and the same minimum breaking force, size for size.

While the 6 x 19 ropes give paramount importance to abrasion endurance in changing degrees, the 6 x 36 ropes are crucial for their fatigue resistance. This fatigue endurance is made feasible by more small wires per strand.

The experts can guide you through different applications of distinguished wire ropes and let you know the choices appropriate for your application.

The Difference Between 7X19, 7X7, 6X19, and 6X36 Wire Ropes

Jul 27, 2022

There is no denying that wire ropes are one of the most used materials in the industrial landscape. According to Statista, in 2020 itself, the production volume of steel wire ropes in Japan amounted to approximately 240.32 thousand tons. Their necessity is evident, and the wire rope sling manufacturers are increasingly deploying their solutions in marine environments or for rigging purposes. However, as wire ropes face considerable loads, they suffer massive mechanical damage.

As suggested by the leading steel wire rope manufacturers, some well-known reasons for wire rope failure are corrosion, excess deterioration, improper usage, and lack of maintenance resulting in reduced safety, increased replacement costs, and early discard. Do you want to know the professional ways steel wire rope manufacturers inspect wire ropes? Then here's a guide for you!

How often should you inspect your wire ropes?

All wire ropes must be inspected visually on daily basis before starting the operation. This safety guideline can ensure maximum security. Although it's daunting to determine the exact service span of the ropes, close analysis on a more frequent basis can help get a more precise estimation of their predictive life cycle. Also, note that calculating the precise times when the ropes have been in use during the mooring/tidal conditions, load pressures, etc., can be the answer. A competent person shall carry out an overall, thorough periodical inspection of the wire rope.

How to inspect a wire rope visually?

Well, you can assess the wire rope condition by standard inspection. Look for signs of:

  • Wire Breaks (Pro tip: valley wire breaks are more hazardous than outer wire breaks)
  • Abrasive damage that is caused by passing over the drum and sheaves during daily use
  • Corrosion is caused by the lack of lubrication. (Pro tip: look for discoloration)
  • Diameter reduction due to excessive abrasion under normal load conditions
  • Crushing or flattening of wire rope strands
  • High Stranding
  • Shock-loading or bird-caging-caused by the abrupt release of tension on the wire rope leading to overloading

The rag and visual method

You can use the rag-and-visual process to check for any external damage. All you need to do is grab the rope lightly with a rag or cotton cloth. Then move the rag along the wire, and if there are any broken wires, they will stick out and snag on the rag. If the cloth catches broken wires, you can stop and assess the rope visually. Also, make sure to visually inspect the wire without any rag because some wire breaks don't stick out.

Measure the rope diameter vividly

Measure the diameter of the rope and compare the diameter with the original values. When the measurements are different, the change implies internal or external rope conditions.

Check for abrasions

When a steel wire rope passes over the drum and sheaves or any other metallic equipment component, abrasion takes place. Hence, it is important that all components must be in proper working order and of the appropriate diameter for the rope. A badly corrugated or worn-out sheave or drum will significantly damage a new rope, resulting in premature rope replacement.

In addition, try to look for corrosion, pitting, abrasions, end fitting conditions, wire breakage (if any), and lubrication inside the rope. Wire rope should be inspected to check for any abnormality like External damage, Kink, Strand looseness, Core protrusion, or Bird-caging.

It is always recommended to maintain the inspection records to assess the rope condition in the next inspection schedule.

Word of caution

While sometimes the damage can be easily identified on the surface, in other cases, the fracture might occur inside the wires. Therefore, ensure that the ropes are maintained, manufactured, and inspected by competent professionals.

Wire ropes have numerous applications in the offshore industries due to their massive strength and durability. Offshore wire ropes, slings, and other rigging equipment handle heavy loads in daily operation. In addition, they are constantly exposed to adverse weather conditions, saline ocean water, etc. Like any machinery and equipment, wire ropes and slings also need proper care and maintenance to ensure their longevity and strength.

That's why we are discussing 5 Care and Safety Tips for Offshore Wire Ropes.

1. Seizing wire ropes

Seizing or cutting wire ropes is vital to deploy them in suitable applications. Moreover, seizing them appropriately is a must to ensure safe and efficient operations. Improper or inadequate seized ends of ropes can be colossal trouble ahead since it can cause flattening of ropes and uneven distribution of load, making it susceptible to premature wear and tear.

2. Routine inspection and cleaning

Since wire ropes are primarily used for heavy equipment lifting, you must conduct regular inspections. Any carelessness or lack of maintenance can cause the ropes to break, resulting in huge losses, accidents, and even fatal injuries. If any change or issue in the rope is noticed during inspection, it must be immediately reported.

3. Ambient lubrication

Although most wire ropes come with original lubrication, it often gets removed due to constant friction and adverse conditions. The wire rope is constantly exposed to environmental elements if the lubrication isn't replenished. Thus, it is advised to maintain proper lubrication to protect the wires and the core from dust, debris, unwanted friction, and corrosion.

4. Professional installation

Are you installing offshore wire ropes on your own? You better leave it to professionals unless you have the proper training. Professional wire rope installers are well-trained in considering every little detail during installation. For example, they use suitable tools like calipers to calculate the rope's nominal diameter to see if it is compatible with the equipment.

5. Proper storage

If you are storing the wire ropes, ensure they are in dry, covered, and well-ventilated conditions. The best practices are keeping them away from moisture, dust, steam, chemicals, and adverse weather conditions.

High-Quality Offshore Wire Ropes: Care and Safety Tips

Jun 29, 2022

Overview

International prices of base metals have gradually slashed from 9 to 17% since April from the soared levels, giving some relief to the related industries, which noticed a sharp rise in input prices. Between April 11 and May 10, a sharp fall of 15%, 9%, and 17% was noticed in the LME, copper, and zinc prices, respectively. China's domestic price of HRC (hot-rolled coil) steel fell by 15%.

As per Trading economics, steel prices have dropped below CNY 4,500 per tonne, a level not seen since last December. They are now roughly 15% below their early May peak due to persistently weak demand and rising inventories.

Some glimpses from the past

In 2021, the steel price in the Indian city of Chennai reached 59.78 Indian rupees per kilogram. On the other hand, steel in Pune was less expensive at 58.08 rupees per kilogram. Therefore, it was projected that steel prices would decrease in all the presented cities. However, driving demand for Indian iron ore in China is said to have increased the steel price in India significantly at the end of 2020.

In India, the steel price varies depending on the cost of import and the prices of other metals and raw materials. Because of these underlying causes, steel prices crashed to ₹65000 per ton from a whopping ₹71000 per ton. Prices were seen at ₹76000 per ton in April 2022, but because of the excess supply during the weak demand, the prices fell with the incoming southwest monsoon slowing the work.

According to analysts, the market expects steel prices to go to ₹60,000 per ton in July 2022 and drop to ₹55000 per ton in August 2022. However, it may not fall further and then gain stability.

Currently, the steel market is in a chaotic condition, and demand is stagnant because of the undercutting done by dealers in expectation of the price reduction by steel manufacturers. Steel price fell by ₹5000 per ton because of the imposition of export duty, and the hot-rolled coil presently hovers at ₹65000 per ton.

 

Major industries affected by the fall in steel prices

A lot of manufacturing units rely on steel for their products and services. From automobile manufacturers to consumer electronics, 'steel' enjoys a huge presence. It is also used for equipment, machinery, steel wire ropes, and hardware production.

The major industries impacted by the fall in steel prices are:

  • Energy
  • Automobile
  • Appliances
  • Construction
  • Steel wire rope
  • Machinery
  • Engineering

 

Here are the reasons why steel prices crashed

Government steps: A rise in export duty

To control roaring steel prices, in May 2022, the government hiked the export duty on finished steel to 15%. However, the government did not include steel intermediaries in the export duties list.

Post this, the semis exports declined by 26% last year to 4.9 MT. However, they may notice a rise in the current financial year. The demand for domestic steel fell by 7.2% every month and is expected to fall more. The fall in the raw material cost will have a positive impact on the manufacturing sector and also help to keep the prices in control. In addition, the fall in import duties of iron ore and steel will enhance domestic availability and further help reduce steel product costs.

 

China's steel demand

As per Fitch experts (an American credit rating agency), the steel demand growth from the construction industries of China has largely peaked in the first six months of 2021. The firm never estimated any demand effect from government incentives after the pandemic struck in April 2020 to support the post-Covid recovery. With current projects and new infrastructural work being taken up, the steel demand will rise during 2022-2025; the company doesn't predict the gush in demand to return from 2022 onwards.
