The manufacturing process of stainless steel pipe fittings

The basic machining process of stainless steel pipe fittings is mainly composed of blanking, forming (welding), heat treatment, surface treatment, cutting processing, nondestructive testing, surface protection and marking.BlankingThe processing materials of stainless steel pipe fittings are usually stainless steel tubes, stainless steel plates and stainless steel bars, and the material properties are determined ...

Corrosion resistance of stainless steel pipe fittings in different environments

1. The atmospheric corrosionThe corrosion resistance of the stainless steel pipe fitting is basically the amount of chloride in the atmosphere. Therefore, it is extremely important to be near the ocean or other chloride sources to corrode stainless steel pipe fitting parts. A certain amount of rain is important only when the chloride concentration of the steel surface ACTS.The rural environment of 1Cr13, 1Cr17 ...

Welding process and treatment of stainless steel pipe fittings

Stainless steel pipe fittings are usually installed when the need for welding, due to the special nature of the material, stainless steel pipe fittings in the welding is different from the ordinary pipe welding. And welding finished the treatment of the weld is different, stainless steel pipe weld not only requires the beauty can not rust, then the stainless steel pipe welding and processing process is how it?As ...

Measures to prolong the use of stainless steel pipe fittings

Stainless steel pipe fittings are widely used in both industrial and civilian applications. The choice of stainless steel pipe fittings when the quality of their own materials will affect its application, and some special industries such as petrochemical, nuclear, medical and other industries on the quality requirements of stainless steel pipe fittings higher. First, the gas protection welding in the welding of ...

For liquid delivery with: water supply, drainage. For gas transmission with: gas, steam, liquefied petroleum gas. For the structure with: for piling pipe, for the bridge; terminal, road, ...

Why is stainless steel pipe fittings relatively difficult to rust?

Stainless steel has the ability to resist atmospheric oxidation --- that is, stainless steel, but also in the acid, alkali, salt medium is the ability to corrosion - that is, corrosion resistance. But its corrosion resistance is the size of its steel chemical composition, plus the state, the use of conditions and environmental media type and change.Such as 304 stainless steel pipe fittings, in the dry and clean ...

Method for calculating the weight of stainless steel pipe fittings

In the purchase of stainless steel pipe fittings and other stainless steel products, usually the price of stainless steel products are measured by its weight, and sometimes we have to know its weight is not accurate, so we must through a certain method to estimate the stainless steel pipe fittings weight. Here are some of the estimated method of stainless steel weight.● Chrome stainless steel to take 7.75 tons / ...
