Steel sheet piles are the most commonly used type due to their high strength, durability, and excellent bending resistance. They are mainly used in cofferdam seepage prevention, basement walls, and wharf retaining walls. They are reusable and suitable for complex geological conditions.

Thin-walled seamless steel pipes are widely used in industries with high requirements for lightweight structures, precision, and performance.

Seamless steel pipes are widely used in industries such as oil and gas, power generation, automotive, and construction due to their high strength and reliability. To ensure consistent quality and safety, each steel pipe must undergo a rigorous quality inspection process before delivery.

Seamless steel pipes play a vital role in the oil and gas industry. These pipes are widely used in transportation pipelines that carry crude oil, natural gas, and refined products.

A steel sheet pile retaining wall is a retaining structure composed of interlocking steel sheet piles. By driving or statically pressing the sheet piles into the ground, a continuous wall is formed to resist lateral pressure from soil or water.

"Schedule" (SCH for short) indicates the wall thickness grade of steel pipe, defined by ASME B36.10 (carbon steel) and ASME B36.19 (stainless steel) standards. The number "40" represents the wall thickness level for a specific pressure rating; the higher the number, the thicker the pipe wall and the stronger its pressure resistance.

ASTM A213 T12 belongs to the 1Cr-1/2Mo pearlescent low-alloy high-temperature steel category. A213 T12 steel has good machinability and weldability, and exhibits high thermal strength and oxidation resistance below 550℃.

ASTM A335 P5 alloy steel seamless pipe, also known as chromium-molybdenum steel P5 pipe or 5Cr-0.5Mo steel pipe, is a high-quality seamless ferritic alloy steel pipe.

High-pressure seamless pipe (also known as high-pressure boiler tube) is a type of seamless steel pipe specifically designed for high-temperature and high-pressure applications, and is an important branch of seamless steel pipes. It is widely used in thermal power generation, petrochemicals, and other industrial fields. Its core characteristics lie in its excellent pressure-bearing capacity and heat resistance.

Pipelines play a crucial role in the transportation of oil, natural gas, and water resources. API pipelines, with their high strength, reliability, and standardized performance, have become the core foundation of global energy transmission systems.

High-frequency welded pipe (HF or HFW pipe) is a type of steel pipe that uses high-frequency current to heat the edges of a steel strip to a welding temperature, then forms a weld seam through extrusion. It is widely used in petroleum, natural gas, building structures, automobile manufacturing, and machining.

Automobiles are one of the important application fields of seamless precision tubes. The key parts of a car, such as the engine, fuel system and braking system, do not require the use of high-precision and high-quality seamless tubes.

Steel sheet piles are a common building material used in foundation engineering and retaining structures. Their edges have special interlocking joints that allow adjacent piles to interlock, forming a tight continuous wall structure. They are widely used in port, dock, river regulation, underground structures, and foundation pit support projects.

Although both ERW steel pipe and spiral welded steel pipe are welded steel pipes, they differ significantly in performance, appearance, and uses due to differences in manufacturing processes, structural forms, and application fields.

Hot-rolled steel is one of the most important intermediate or terminal products in the steel production process. It mainly refers to heating the steel billet above the recrystallization temperature and rolling it into various shapes through a rolling mill.
