Among various types of steel pipes, spiral welded pipes (typically referring to SSAW spiral double-sided submerged arc welded pipes) have become the most commonly used steel pipes in construction and water transportation due to their unique manufacturing process and extremely high cost-effectiveness.

Seamless carbon steel pipes are widely used in pipeline engineering and industrial manufacturing due to their high strength and pressure resistance. However, carbon steel itself has poor corrosion resistance and is prone to rusting.

In modern piping systems, pipe selection is crucial, directly impacting the safety and durability of the entire system. Among various pipe specifications, Schedule 40 seamless steel pipe is one of the most commonly used solutions due to its balanced performance in terms of strength, pressure resistance, and cost.

In the fluid transportation field, ERW (Electric Resistance Welded) steel pipes have become one of the most commonly used types of steel pipes in modern infrastructure. Whether for municipal drinking water systems, industrial cooling loops, or agricultural irrigation, selecting the right ERW steel pipe is crucial for pipeline durability and safety.

Valves are commonly used pipe fittings in systems such as oil transportation, natural gas, water, and steam. The rated pressure of a valve is crucial for ensuring the normal operation of the system. This article will detail the rated pressure of valves and its role in engineering design.

AWWA C205 is an authoritative standard developed by the American Water Works Association (AWWA) for "Cement Mortar Lining and External Corrosion Protection of Steel Water Pipes." Due to its superior durability and cost-effectiveness, CML steel pipes have become the preferred solution for water infrastructure worldwide.

Mild steel cement lined pipe (MSCL) are the most commonly used pipes in the water supply industry due to their superior durability and cost-effectiveness. They combine the high mechanical strength of carbon steel with the excellent corrosion resistance of cement mortar, offering a service life of 50 to 100 years.

Large-diameter straight seam welded pipe refers to LSAW pipes with a larger diameter. LSAW is an abbreviation for Longitudinal Submerged Arc Welding.

STM A252 Grade 2 steel pipe piles have become one of the most widely used structural steel pipes in the engineering field due to their excellent load-bearing capacity and excellent cost-effectiveness.

Pipe end treatment is a crucial yet often overlooked step. It directly determines the welding quality, connection reliability, system sealing, and on-site construction efficiency.

Schedule 10S is a standardized pipe wall thickness series clearly defined by ASME B36.19 (Stainless Steel Pipe Standard).

Electric Resistance Welding (ERW) steel pipe has become one of the most widely used pipe materials in industrial applications today due to its excellent economy and continuously improving manufacturing process.

A piping pressure rating, also known as the maximum allowable working pressure (MAWP), refers to the highest internal fluid pressure that a pipe, fitting, or flange can safely and continuously withstand at a specific operating temperature.

Hot rolling and cold rolling are two of the most fundamental and critical metal forming processes. These processes not only determine the physical appearance of steel but also directly affect its mechanical properties, dimensional accuracy, and final cost.

Anti-corrosion spiral steel pipe (SSAW/SAW pipe) is not a single type of steel, but a combination of a base material and a protective system.
