Properties and uses of 316 and 316L stainless steel
316 and 317 stainless steel are molybdenum-containing stainless steel species, and the molybdenum content in 317 stainless steel is slightly higher than that of 316 stainless steel. Due to the molybdenum in the steel, the overall performance of this steel is better than that of 310 and 304 stainless steel. Under high temperature conditions, when the concentration of sulfuric acid is lower than 15% and higher than 85%, 316 stainless steel has a wide range of uses. 316 stainless steel also has good chloride attack properties, so it is often used in marine environments.
316L stainless steel has a maximum carbon content of 0.03 and can be used in applications where annealing after welding is not possible and where maximum corrosion resistance is required.

How is stainless steel welded pipe produced
In the 19th century, rolling technology was the only technology used to produce stainless steel and industrial tubes. The process steps involved in this rolling technique are long. It is with the help of funnel rolls that the rolled sheets are made into circular cross-sections and these rolled strips are then welded in a welding process
Fortunately, with development and new technologies, various processes for manufacturing stainless steel tubes and pipes have been formed Stainless steel tubes and tubes are now manufactured by continuous tube mills using tungsten inert gas. No filler metal or forge welding process is used in this technique.

Comparison between ERW steel pipe and LSAW steel pipe
The difference between ERW straight seam electric resistance welded steel pipe and straight seam submerged arc welded (UOE) steel pipe:
Straight seam welded steel pipes are divided into high-frequency resistance welding and submerged arc welding according to the welding process. Straight seam submerged arc welding is referred to as UOE, and straight seam high-frequency resistance welding is referred to as ERW.

Introduction of Production Technology of Large Diameter Longitudinal Welded Pipe
Longitudinal welded pipes are made of steel plates or strips that are bent and then welded. According to the weld form, it is divided into straight seam welded pipe and spiral welded pipe. According to the purpose, it is divided into general welded pipe, galvanized welded pipe, oxygen blown welded pipe, wire casing, metric welded pipe, idler pipe, deep well pump pipe, automobile pipe, transformer pipe, electric welded thin-walled pipe, electric welded special-shaped pipe and spiral welded pipe.

Complete knowledge of welded pipe
We can also call the welded pipe a welded steel pipe. Its manufacturing process is to weld some steel plate profiles or some materials containing steel components into the shape of a steel pipe after crimping and forming. The production method of welded steel pipe is very simple, the production efficiency is high, and there are many types and specifications of it, and the cost of production is very small, but the only disadvantage is that compared with seamless steel pipe, its strength is higher lower than seamless steel pipe

What is a welded steel pipe
La tubería de acero soldado, también conocida como tubería soldada, es una tubería de acero hecha de placa de acero o tira de acero después de engarzar y soldar. El proceso de producción de tubos de acero soldados es simple, la eficiencia de producción es alta y hay muchas variedades y especificaciones, pero la resistencia general es menor que la de los tubos de acero sin costura.
Los espacios en blanco utilizados para los tubos de acero soldados son placas de acero o tiras de acero, que se dividen en tubos soldados en horno, tubos soldados eléctricamente (soldadura por resistencia) y tubos soldados por arco automático debido a sus diferentes procesos de soldadura. Debido a sus diferentes formas de soldadura, se divide en dos tipos: tubería soldada con costura recta y tubería soldada en espiral. Debido a la forma de su extremo, se divide en tubería soldada redonda y tubería soldada de forma especial (cuadrada, plana, etc.).

Welded steel pipe standards and materials
Welded steel pipe, also known as welded pipe, is a steel pipe made of steel plate or strip steel after crimping and welding. Welded steel pipe has simple production process, high production efficiency, many varieties and specifications, and less equipment investment, but its general strength is lower than that of seamless steel pipe. Since the 1930s, with the rapid development of continuous rolling production of high-quality strip steel and the advancement of welding and inspection technology, the quality of welds has continued to improve, and the variety and specifications of welded steel pipes have increased day by day. Seam steel pipe. Welded steel pipes are divided into straight seam welded pipes and spiral welded pipes according to the form of the weld seam.
