welded spiral steel pipe for oil and gas transportation. Oil & gas transportation Spiral Steel Pipe is adopt the Double Side Spiral Submerged Arc Weld technology.Physical and chemical inspections of the raw materials,welding wires and welding flux.and it is widely using for the long distance transferring of water,petroleum,natural gas,coal gas and pulp,etc. Specification:O.D:219mm-3048mm W.T Common pipe type-Q235B spiral steel pipes ASTM A234 Q235B spiral pipe is a commonly used raw material in spiral pipes.It is a spiral seam steel pipe welded with strip steel coil as the raw material and active double wire double-sided submerged arc welding.The main technical characteristics of the spiral steel pipe:During the forming process, the steel plate is uniformly deformed, the residual stress is small, and the surface does not scratch. Comparison of Characteristics Between ERW Steel Pipe and Feb 26, 2020 · Both straight seam resistance welded steel pipes (ERW steel pipe) and spiral submerged arc welded steel pipes (SSAW steel pipe) can better meet the requirements of oil and gas pipelines.For medium-diameter (630mm) steel pipes, ERW steel pipes are mostly used abroad. Spiral submerged arc welded pipes are generally only used for low-pressure fluid transmission, civil
The spiral submerged arc pipe is divided into three layers from the inside to the outside. The working steel pipe layer is generally made of seamless pipe (gb8163-87) and spiral welded pipe (gb9711-88). According to the planning and customer requirements. SY t5038-92) and straight seam welded pipe (gb3092-93). After the appearance of the steel How to Carry Out Quality Inspection of Spiral Steel Pipe Jul 27, 2020 · Spiral steel pipe is a spiral seam steel pipe made of strip steel coils as raw materials, often extruded and formed by automatic double-wire double-sided submerged arc welding. Spiral steel pipes should be subjected to mechanical performance test, flattening test and flaring test before leaving the factory, and must meet the requirements of the Impact of Covid-19 on Helical Submerged Arc Welding Helical Submerged Arc Welding (HSAW) Steel Pipe Industry Analysis 2020. The Helical Submerged Arc Welding (HSAW) Steel Pipe Market report enlightens its readers about its products, applications, and specifications. The research enlists key companies operating in the market and also highlights the roadmap adopted by the companies to consolidate their position in the market.

As we know,seamless steel pipe always is small dimension,longitudinal submerge arc weld steel pipe is large dimension,but for larger dimension,we should use the method of spiral submerge arc welding instead of longitudinal submerge arc welding.With this method,we can use narrow width steel plates to produce large dimension pipes.The outside diameter is determined by the angle of the de-coiled Spiral submerged arc welding, SAW pipe - Sunny SteelSpiral submerged arc welding as raw material is often warm extrusion molding, automatic double -sided wire submerged arc welding process. The process is normally limited to the flat or horizontal-fillet welding positions (although horizontal groove position welds have been done with a special arrangement to support the flux). Submerged arc welding pipe, SAW pipes, SAW pipe As ERW steel pipe and SAW steel pipe in the pipe during forming, welding and process is different, so that two kinds of steel pipe in the performance there are some differences. ERW steel pipe surface quality is superior to spiral submerged arc welded pipe, ERW steel pipe surface is smooth, smooth, beautiful, SAW steel pipe internal and
The spiral welded pipe is a high-durability steel pipe that is frequently used in different industries. It is made up of a hot-rolled coiled steel strip using a double-sided submerged arc welding method to produce large-diameter steel pipe sizes. The spiral welded pipe is also known as the SSAW steel pipe is one of the key products developed by api 5l submerged arc welding spiral steel pipe - Carbon SSAW,SSAW pipe,SSAW steel pipe,Spiral submerged arc .
