The inspection of stainless steel wire in stainless steel wire rope is carried out during the test of the dismantling of the stock, Stainless Steel Wire Ropes and the stainless steel wire detected by it adopts the steel wire which needs mechanical properties and toughness testing.
The diameter of stainless steel wire is detected by micrometer or vernier caliper, Stainless Steel Wire Ropes and the measured diameter is the arithmetic mean of measuring the diameter of two times in the same cross-section perpendicular to the steel wire. The difference in diameter of two measurements is called the ellipse degree of steel wire.
Stainless steel wire diameter detection can be removed to do the zinc coating quality test (usually the total number of silk 10%) outside of all steel wire, Stainless Steel Wire Ropes can also be separated after the same nominal diameter of the wire after the complete mixing, and then arbitrarily select the appropriate amount of steel wire for testing. The tolerance of wire diameter in stainless steel wire rope is stipulated in the standard of stainless steel wire rope.
Stainless steel wire Rope in many industries has a very wide range of applications, foreign countries have been widely used in the construction of internal and external pipelines, Stainless Steel Wire Ropes the general use of two stainless steel grades: 304 and 316. Stainless steel wire rope relative to other material pipelines, has the following advantages:
(1) coating steel wire rope corrosion resistance is good;
(2) strong and ductile good;
(3) easy forming and welding;
(4) The maximum flow rate can reach 30 m/s without the restriction of water velocity;
(5) applicable to all kinds of drinking water chemical composition;
(6) The maintenance quantity is small, therefore the life cycle cost is low;
(7) Various connecting methods and different types of joints;
(8) In addition to the need to control bacteria, do not need any water treatment agent;
(10)-0% recovery and utilization;
(11) The appearance of beautiful buildings in the piping can be considered.
The initial cost of stainless steel is generally high, but there are many ways to save money, for example, it does not require corrosion-resistant coating, can reduce the cost of standby equipment, Stainless Steel Wire Ropes stainless steel parts light weight, the need for less structural support; lighter parts, lower transportation and installation costs; No corrosion allowance is required to reduce the thickness of the thin tube wall.
Although the initial cost of stainless steel is relatively high, its life cycle costs are generally lower because of the cost savings:. Smooth inner surface can reduce the pump energy consumption, can reduce the number of inspections and costs, reduce maintenance costs. No need to paint again, Stainless Steel Wire Ropes no need to replace, reduce downtime, prolong service life. After the end of service life can be 100% recycled.
