Steel piles, as an important material for support and foundation structures, mainly include two types: pipe piles and sheet piles. Steel piles play a crucial role in bridge, construction, port, foundation pit and coastal engineering.

EFW (Electric Fusion Welded) steel pipe, also known as electric fusion welded steel pipe, is a kind of longitudinal straight seam welded pipe formed by melting and welding the edges of the steel strips on both sides by arc or resistance melting process.

In various piping projects, it is crucial to understand the difference between Schedule 40 (SCH 40) and Schedule 80 (SCH 80) piping.

Among various types of pipes, seamless pipes and seam pipes have become the two most common types due to their unique manufacturing processes and performance characteristics.

Resistance welded Pipes (ERW Pipes) have become key materials in oil and gas pipeline engineering due to their excellent mechanical properties, controllable weld quality and significant cost advantages.

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.
