What kind of wire rope flaw detector is suitable for you?

Wire rope flaw detector is used to detect the abrasion and broken wire of wire rope, so as to determine whether it is necessary to replace a new wire rope, so as to achieve the purpose of safe use of wire rope, because the sudden fracture of wire rope is easy to lead to major accidents, and replacing a new wire rope prematurely will increase the cost, which is the use value of wire rope flaw detector, and only wire rope flaw detector can achieve this goal and is suitable for itself.

The main varieties of wire ropes in China are as follows:

1. Phosphate coated steel wire rope (China patent). After phosphating with manganese series and zinc-manganese series, the wear resistance and corrosion resistance of steel wire rope have made a leap. The fatigue life of phosphating steel wire rope is three times that of smooth steel wire rope with the same structure (under comparable conditions in the laboratory), which exceeds that of imported steel wire rope, and phosphating steel wire rope is completely replacing all kinds of smooth steel wire rope. It can also replace galvanized steel wire rope which is electroplated first and then thinned with zinc layer (salt spray test can be used).

2. Galvanized steel wire rope, including hot dip galvanizing and electro-galvanizing. The thicker the zinc coating, the stronger the corrosion resistance. The thickness of zinc coating is expressed in grams per square meter.

3. Stainless steel wire rope, mainly made of 304 or 3 16 stainless steel, has excellent anticorrosion effect, but it is expensive.

4. Based on plastic-coated steel wire rope and carbon steel wire rope, the outer layer is coated with polyethylene, polypropylene or nylon.

5. Smooth steel wire rope has a short service life and the market demand drops sharply, so it is being completely eliminated by phosphating coated steel wire rope.

For hoisting machinery used in atmospheric environment, manganese phosphating coated wire rope is preferred, hot dip galvanized-phosphating double-coated wire rope is preferred in heavy corrosive environment, and marine wire rope is preferred in seawater. Please note that the name of wire rope must be indicated on the purchase invoice, such as phosphating coated wire rope or 3 16 stainless steel wire rope, to prevent illegal enterprises from infringing their legitimate rights and interests with counterfeit products. In addition, patented products will generally be marked with the patent number on the outer package of steel wire rope, and the warranty should have the main technical indicators, such as the type and weight of phosphating film (phosphating film has an important impact on the service life of steel wire rope, such as wear resistance and corrosion resistance, etc.), for reference only.
