low-carbon steel
Welded, too low strength.
Hoisting machinery
The main varieties of commonly used wire ropes are as follows:
1. Phosphating coated steel wire rope (patented technology), the steel wire material is manganese series or zinc-manganese series.
Phosphate antirust treatment of metal surface
The wear resistance and corrosion resistance of steel wire surface have all jumped.
Phosphating film
and
grease lubricant
The composite action of steel wire rope can effectively restrain fretting wear and completely solve the wear problem of steel wire rope in use.
fatigue life
3 rounds of smooth steel wire rope with the same structure, passing through.
Fatigue test
It can verify the fatigue life (it is the most reliable to do fatigue test in person), and it is an upgraded product of smooth steel wire rope, and can also replace zinc coating first.
galvanized steel wire rope
Use (available through.
salt spray test
Corrosion resistance inspection or comparison), long service life, lower unit use cost and better stability.
2. Galvanized steel wire rope, including
hot galvanizing
and
electrogalvanizing
Two kinds, generally speaking, the galvanized layer is thick and the galvanized layer is thin.
3.
Stainless steel wire rope
, and 304 or
3 16 stainless steel
The main reason is that the anticorrosion effect is good but the price is expensive.
4.
plastic coated steel wire rope
Carbon steel wire rope coated with polyethylene, polypropylene or nylon.
5. Smooth steel wire rope, with short service life and sharp drop in market demand, will be completely eliminated by phosphating coated steel wire rope.
6.
ocean engineering
Mooring wire rope
7. Wire rope
Atmospheric environment
Phosphate coated steel wire rope is preferred for hoisting machinery used in this project, hot dip galvanized-phosphating double coated steel wire rope is preferred for severe corrosive environment, and marine steel wire rope is preferred for seawater. Please note that the purchase invoice must indicate the name of the wire rope, such as phosphating coated wire rope or
3 16 stainless steel wire
Rope, protect their legitimate rights and interests, in addition,
Patented product
Generally, the outer packaging of steel wire ropes is marked with the patent number by spraying, and the main technical indicators such as the type and weight of phosphating film should be on the warranty book for reference only.
