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 -
Processing method of stainless steel pipe fittings
Stainless steel pipe fittings are a new type of pipe fittings that are widely used. Generally speaking, the processing methods are as follows : 1. Forging method: the end or part of the pipe is punched out with a swaging machine to reduce the outer diameter. Common swaging machines include rotary...Read more -
Stainless steel does not rust
Stainless steel is an extremely thin, strong, dense, and stable chromium-rich oxide film (protective film) formed on its surface to prevent the relay of oxygen atoms. Continue to penetrate, continue to oxidize, and obtain the ability to resist rust. Once for some reason, this kind of film has bee...Read more -
Connection method of carbon steel seamless pipe
(1) The importance of heavy industrial structures, large-span structures, high-rise or super-high-rise civil building structures or other important structural structures, should consider the selection of high-quality seamless steel pipes, generally according to the working nature of industrial an...Read more
