How Can We Distinguish The Difference Between Welded Steel Pipe And Spiral Steel Pipe?

Industrial production and manufacturing can not be separated from the use of various steel pipe needs, whether it is pipeline welding, or all kinds of industry special material handling and liquid gas transportation transmission, need a large number of welded steel pipe pipeline connection, such as oil and gas pipeline transportation these.

Welded steel pipe is a steel pipe with seams on the surface, bent into a round, square and other shapes with a steel strip or plate. Welded steel pipe selection of billet for steel or strip, with the type of welded steel pipe and quality specifications continue to improve, welded steel pipe range is becoming more and more extensive, welded steel pipe cost is lower than the seamless steel pipe, high production efficiency, this is due to the rapid development of continuous rolling of high-quality strip and the promotion of welding inspection technology.

Light Pipe Radiator is made of steel pipe,according to different structure and medium,it can be divided into Light Pipe Radiator A and Light Pipe Radiator B. Seamless steel pipe or welded steel pipe according to people's requirement to choose two kinds of raw material for radiator,all parts of seamless steel pipe are better than welded steel pipe.

The steel pipe of spiral welded pipe is divided into seamless steel pipe and welded pipe, and the welded pipe is divided into straight seam steel pipe and spiral steel pipe. Straight seam welded pipe is divided into ERW (high frequency resistance welding) and LSAW (straight submerged arc welding). Spiral welding process is also submerged arc welding (SSAW) and LSAW is the difference between the welding method, the difference between SSAW and ERW is the difference between the welding process, submerged arc welding (SSAW) is to add media (wire, flux), ERW is not required, ERW is medium frequency heating and melting. Steel pipe can be divided into two categories according to the production method of seamless steel pipe and welded steel pipe. Seamless steel pipe can be divided into hot-rolled seamless steel pipe, cold-drawn pipe, precision steel pipe, hot-expanded pipe, cold-rotated pipe and so on. Seamless steel pipe is made of high quality carbon steel or alloy steel, including hot rolled and cold rolled.

The production process is simple, high production efficiency, low cost and fast development. The strength of spiral welded pipe is generally higher than that of straight seam welded pipe. Can produce large diameter narrow billet welded pipe, can also produce different diameter welded pipe. But compared with long straight seam pipe, the welding length increases by 30~100%, and the production speed is lower. So most of the small diameter welded pipes are welded with straight seam, and large diameter welded pipes are welded with spiral.

Welding process is the core part of machinery manufacturing. For the world's leading construction machinery manufacturers, it is critical that each component can be precisely welded. Welding is not just a production aspect of welding. In order to accomplish this work in the most meticulous way, companies can start from understanding the production task, control each production link in fine detail, and produce products to meet customers' needs. From production assembly to welding, they should order or design their own products according to their needs.
