LSAW and SSAW are two common manufacturing processes for welded steel pipes. LSAW stands for Straight seam Submerged arc welded steel pipe, while SSAW stands for spiral seam submerged arc welded steel pipe.

SSAW (Spiral Submerged Arc Welded) steel pipe is a kind of large-diameter and high-strength welded pipe made by rolling the steel strip at a specific spiral Angle and applying Submerged arc welding technology at the spiral seam.

LSAW steel pipe, also known as straight seam submerged arc welded steel pipe, is made by using steel plates as the base material, processing them into shape, and then performing submerged arc welding along the longitudinal direction of the steel pipe to form large-diameter and high-strength welded steel pipes.

With the dual demands for the performance and cost of Pipe materials in industrial and infrastructure construction, black carbon Steel pipes have gradually become the preferred pipe materials in fields such as gas, fire protection, and building support due to their natural anti-rust layer, high strength, and highly competitive price.

Carbon steel square pipe has become an indispensable structural material in modern construction, mechanical manufacturing and decoration projects due to its regular cross-sectional shape, excellent strength-to-weight ratio and high processing flexibility.

Carbon Steel Welded Pipe is a type of pipe made from carbon steel materials through welding processes and is widely used in various industrial fields, such as petroleum, natural gas, chemical industry, construction, water transmission, mechanical manufacturing, etc.

galvanized carbon steel pipe refers to a steel pipe with carbon steel as the base material and a layer of zinc coated on its surface.

Carbon steel pipe is a type of steel pipe mainly composed of carbon and iron, and also contains trace amounts of manganese, silicon, phosphorus, sulfur and other elements. According to the difference in carbon content, it can be classified into low-carbon, medium-carbon and high-carbon grades. With the increase of carbon content, its strength increases but its toughness and weldability decrease.

ERW (Electric Resistance Welded) carbon steel pipe is a kind of steel pipe that heats the edge of the steel strip by high-frequency current and is welded and formed under pressure.

Stainless steel threaded pipe fittings are a type of metal connecting parts used to connect different pipe sections in pipelines or pipe systems. Their main bodies are made of stainless steel and have internal or external threads (such as NPT (American Standard conical thread) or BSP (British standard thread), and can be installed without welding through rotary connection.

Stainless steel is a highly alloyed material. It is a general term for metal alloys containing 12% or more chromium (Cr) and over 50% iron (Fe), featuring high hardness, corrosion resistance and other advantages.

904L stainless steel pipe is a high-alloy, super-austenitic stainless steel pipe with copper added to the stainless steel alloy.

Metal pipes are an indispensable part of modern life. They can not only be used in daily life and production, but also in various industrial environments for transporting water, oil, gas and other chemical media.

Stainless steel welded pipes are made by rolling and butt stainless steel strips or plates and then welding them along the pipe axis to form round or square or rectangular pipes.

2 inch (nominal diameter approximately 50.8mm, actual outer diameter ≈ 60.3mm) stainless steel pipes possess excellent mechanical properties and corrosion resistance, making them highly practical industrial and decorative materials and versatile in numerous fields.
