Welded Steel Pipes

Tramadol Online Cash On Delivery Welded steel pipe is a steel pipe with seams on the surface that is bent and deformed into a round or square shape by steel strips or plates and then welded. Welded steel pipe is less costly and more efficient than seamless steel pipe, and the billet used is steel plate or strip steel. Welded steel pipe is highly resistant to corrosion in acidic environments.

Furnace welded pipe: can be used as water and gas pipe, etc. Large diameter straight seam welded pipe is used for high pressure oil and gas transmission, etc.; spiral welded pipe is used for oil and gas transmission, pipe piles, bridge piers, etc.

Classification by weld seam shape: can be divided into straight seam welded pipe and spiral welded pipe

Spiral type : The strength is generally higher than that of straight seam welded pipe, and it can produce welded pipe with a larger diameter from a narrower billet, and it can also produce welded pipe with a different diameter from a billet of the same width. However, compared with the same length of straight seam pipe, the weld length increases by 30~100% and the production speed is lower. Therefore, most of the smaller diameter welded pipes are straight seam welded, and most of the large diameter welded pipes are spiral welded.

Spiral welded steel pipe is divided into two kinds of automatic submerged arc welded steel pipe and high-frequency welded steel pipe.

Spiral automatic submerged arc welded steel pipe according to the pressure of the transport medium is divided into two categories: Class A pipe and Class B pipe. Class A pipes are generally made of ordinary carbon steel Q235, Q235F and ordinary low-alloy structural steel 16Mn welded, Class B pipes are made of Q235, Q235F, Q195 and other steel welding, used as low pressure fluid transfer pipe
