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 -
Construction advantages of TPEP anti-corrosive steel pipe and PCCP pipeline
Construction advantages of TPEP anti-corrosive steel pipe and PCCP pipeline Construction advantages: 1.Low requirements for basic construction conditions. 2.The steel pipe has large deflection and is laid in special environments such as swamps and rivers. When the local water level rises, trench ...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
What is the difference between fine polishing and rough polishing of stainless steel pipe fittings Rough polishing is the rough grinding and cutting of metal objects. Usually, this kind of automatic polishing machine uses double polishing heads for polishing. The advantages of this rough polishin...Read more -
Production characteristics of stainless steel seamless pipe
The production characteristics of stainless steel welded pipes The continuous roll forming into stainless steel welded pipes below φ219mm is similar to the high-frequency straight seam welded pipes above φ219mm using pressure forming (UOE) or spiral welding (see spiral welded pipes). The capillar...Read more -
Three welding techniques for stainless steel welded pipe
At present, the welding methods of stainless steel welded pipes used in the industry mainly include argon arc welding, high-frequency welding, plasma welding, and laser welding. Several welding methods have their characteristics. At present, argon arc welding and high-frequency welding are the mo...Read more -
What should be paid attention to when welding galvanized steel pipe
What should be paid attention to when welding galvanized steel pipe 1. The premise must be polished The galvanized layer of the weld must be polished away, otherwise air bubbles, trachoma, false welding, etc. will occur. It will also make the weld brittle and reduce the rigidity. 2. The welding c...Read more -
Preventive measures for improper connection when a galvanized steel pipe is connected
Preventive measures for improper connection when a galvanized steel pipe is connected 1. In the selection of pipe materials, high-quality should be selected; the connection method should be finally determined through the design specification requirements and the size of the pipe fittings. The con...Read more -
The main production process of large diameter straight seam welded pipe
1. Plate exploration: After the steel plate used to manufacture large-diameter submerged arc welded straight seam steel pipe enters the production line, the full plate ultrasonic inspection is first performed; 2. Edge milling: double-sided milling of the two edges of the steel plate by a milling ...Read more -
Precautions for welding stainless steel pipe fittings
1. In order to prevent erosion due to heating, the welding should not be too long. It should be 20% less than the carbon steel electrode. The arc should not be too long. The layers should be cool quickly. The narrow weld bead is suitable. 2. The hardening of the stainless steel pipe fittings is q...Read more
