API 5L pipes are carbon steel pipes used for oil and gas transmissions. They include pipes manufactured in seamless and welded (ERW, SAW). The grades include API 5L Grade B, X42, X46, X52, X56, X60, X65, X70, X80 PSL1 & PSL2 onshore, offshore and sour services. API 5L is the implementation standard of steel pipe for pipeline transportation systems and specification for line pipe.

ASTM A500 standard defines the technical conditions for cold-formed welded and seamless carbon steel and mild steel structural pipes, including square, rectangular and other hollow sections. This type of steel pipe is particularly suitable for applications such as building structures, bridges, traffic sign brackets, etc. that require high strength and good appearance.

Corrugated steel pipes (CSP) are a highly versatile and durable solution for a wide range of applications, particularly in drainage and stormwater management. These pipes are known for their strength, longevity, and ability to withstand various environmental conditions. CSPs are available in multiple coatings and configurations to suit specific project needs.It is a type of pipe made from thin, ribbed sheets of steel that are formed into a corrugated shape and then joined together. This type of pipe is typically used for culverts, storm drains, and other types of underground infrastructure.

Square pipe is a name for square pipes, that is, steel pipes with equal side lengths. Square tubes can be divided into seamless square tubes and welded square tubes according to the presence or absence of welds. Seamless square pipe is a square steel pipe with four corners. It is a square steel pipe formed by cold drawing and extrusion of seamless pipe. There is an essential difference between seamless square pipe and welded square pipe. Steel pipes have a hollow section and are used in large quantities as pipes for transporting fluids. Welded square tube is a square tube made of steel plate or strip steel after crimping and welding.

carbon steel pipes are divided into general steel pipes, low and medium pressure boiler steel pipes, high pressure boiler steel pipes, alloy steel pipes, stainless steel pipes, petroleum cracking pipes, geological steel pipes and other steel pipes.

Galvanized steel pipe is a welded steel pipe with a hot-dip or electroplated zinc layer on the surface. Galvanizing can increase the corrosion resistance of steel pipes and extend their service life. Galvanized pipes are widely used. In addition to being used as pipeline pipes for general low-pressure fluids such as water, gas, and oil, they are also used as oil well pipes and oil pipelines in the petroleum industry, especially offshore oil fields, and as oil heaters and condensators in chemical coking equipment. Pipes for coolers, coal distillate wash oil exchangers, pipes for trestle pipe piles, and support frames for mine tunnels, etc.
