Generally, the reliable operating pressure range for SCH 40 pipe is from 690 PSI to nearly 3,000 PSI, depending on the diameter.

In industrial piping systems, Schedule 40 black pipe is the most common and widely used type of pipe product. Due to its pressure resistance, strength, corrosion resistance, and economy, it is widely used in water supply, fire protection, natural gas, petrochemical, HVAC systems, and building structural support.

In various foundation and retaining wall projects, the selection of sheet piles is a core factor affecting the safety, durability, and economy of the project.

Schedule 10 (SCH 10) carbon steel pipes, with their lightweight, high cost-effectiveness, and excellent applicability to medium and low pressure, have become the preferred solution for many engineering projects.

Oil casing pipe is a key component in oil and gas well construction. It primarily supports the wellbore, prevents wellbore collapse, isolates different geological layers, and ensures stability during drilling and long-term safe operation of the well after completion. Unlike reusable drill pipe and tubing, casing is a disposable material and a major consumable product in oil wells.

Schedule (SCH) 10 refers to the wall thickness grade of steel pipes. Other grades include SCH40 and SCH80. A higher number indicates a thicker wall and stronger pressure resistance.

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.
