Pipe fittings for pipeline connection
Pipe fittings are used for pipeline connections, such as elbows, size ends, tees, caps, elbows, etc. These pipe fittings are mainly used in petroleum, chemical, electric power, shipbuilding, construction industries, and other fields. For example, some indoor heating pipes need to be connected wit...Read more -
Under what circumstances can stainless steel pipe fittings be welded by argon arc, and under what circumstances can be welded by arc welding
Under what circumstances can stainless steel pipe fittings be welded by argon arc, and under what circumstances can be welded by arc welding 1. Argon arc welding is a welding technique that uses argon as a shielding gas. Also called argon gas shielded welding. It is to pass argon shielding gas ar...Read more -
Connection method of stainless steel water supply pipe
1. Compression type: Insert the piping into the pipe fittings. Both ends of the pipe fittings are protruding U-shaped grooves with built-in sealing rings. Use special pipe fitting tools to press the socket parts for connection. Scope of application: DN (nominal diameter) ≤100mm, can be installed ...Read more -
The role of chromium and nickel in stainless steel pipes
Stainless steel pipe is a broad term for iron-based alloy steel with chromium content exceeding 13%, which has anti-corrosion and anti-oxidation properties through the passivation of chromium. The main component of the stainless steel pipe is iron. There is just one element that determines the pr...Read more -
Hot rolling process in stainless steel pipe fittings
Hot rolling process in stainless steel pipe fittings Simply put, the process of rolling steel material after heating it to a temperature above the recrystallization temperature is called hot rolling. And below the recrystallization temperature, the process including rolling at room temperature is...Read more -

Knowledge of rolling surface processing of stainless steel pipe
Knowledge of rolling surface processing of stainless steel pipe 1. After hot rolling, annealing, pickling, and descaling, the surface of the treated stainless steel plate is a dull surface and a bit rough; 2. It is a better process than the general surface, and it is also a dull surface. After co...Read more -
Comparative advantages of glass steel pipe and steel pipe
1. Design flexibility FRP pipes have to design flexibility and can be designed and manufactured for any combination of applicable technical parameters, which can meet the needs and requirements of customers. However, the design of steel pipes is less pertinent and only has this to a certain exten...Read more -
Anti-corrosion of the inner wall of large diameter steel pipe
1. Before processing all steel pipes, the steel plate on the inner wall of the large-diameter steel pipe should be de-rusted, and it is required to reach the metal luster (whitening). 2. The steel after rust removal should be processed immediately (to prevent secondary rust). After processing, us...Read more -
What is the difference between fine polishing and rough polishing of stainless steel pipe fittings
