Type discrimination of alloy steel flange. Different from ordinary 20 #, Q235 and other carbon steel flanges, it is mainly used for special characteristics of pipelines and pipelines, mostly for high temperature and high pressure positions. Its common materials are 12Cr1MoV, 15CrMo, P91, P22, 10CrMo910 and so on. The implementation standards include national standards, Ministry of Chemical

Forged pipe fitting — In the pipe manufacturing industry, the broad concept of “forging” refers to the use of pipes, sheets and forgings as raw materials, and its manufacturing methods include almost all the contents of the pipe forming process. When it comes to specific types (including all kinds of socket welding and threaded pipe fittings, brackets

There are many applications of different diameter pipe in our life, but there are many people who do not know it very well, do not know the type of forged pipe, do not know its use, these are to be known before use. Types of diameter steel pipe: 1. According to its curvature radius, it can

Flat welding flange and butt welding flange are common integral flanges of large flanges. Flat-welded flange has poor rigidity, which is suitable for pressure P < 4 MPa. Butt-welded flange is also called high neck flange, which has high rigidity and is suitable for high pressure and temperature occasions. There are three types of flange

There is a kind of flange fittings product in pipe fittings industry. Flange is a kind of equipment connecting pipelines. It has many kinds of classifications, such as national standard, American standard, Japanese standard, non-standard, high and low pressure according to pressure, stainless steel, alloy steel, carbon steel and so on. Today we want to say that

Pipe fittings belong to one kind of pipe fittings. It is made of stainless steel material, so it is called stainless steel pipe fittings. It includes stainless steel elbow, stainless steel tee, stainless steel four-way, stainless steel diameter pipe, stainless steel pipe cap, etc. According to the connection method, it can be divided into socket stainless

Where does the name of stainless steel pipe come from? According to experts in the industry, stainless steel pipe fittings belong to one kind of pipe fittings. It is made of stainless steel material, so it is called stainless steel pipe fittings. It includes: stainless steel elbow, stainless steel tee, stainless steel tee, stainless steel four-way, stainless

The basic difference between stainless steel elbow and elbow is that stainless steel elbow is shorter than elbow. R = 1 to 2 times is the elbow, and the bigger one is the elbow. In the production process, the cold bending pipe can be bent by a ready-made straight pipe bender, and no secondary corrosion

Stainless steel elbow, the elbow of the product has an inner lining at the pipe orifice. One part of the inner lining is located in the pipe orifice, which is fixed to the wide inner wall. The other part of the inner lining is located outside the pipe orifice. The inner lining of the product
