ASTM A270 Sanitary stainless Steel pipe is the standard specification for welded seamless, heavy cold work welded austenitic and ferritic stainless steel sanitary pipe.

Spiral steel pipe is a kind of welded steel pipe, is a common building material, suitable for the construction of Bridges, docks, tunnels, etc.

DIN 1629 is the standard for seamless round tubes of non-alloy steel with special quality requirements. It is a German standard that specifies the requirements for non-alloy steel seamless round steel pipes.

Hot rolled seamless pipe is made by calcination of billet at high temperature, perforation, rolling, sizing, straightening and other process steps.

With the development of society and the continuous advancement of the industrialization process, the diversification of pipes has become more and more important.

With the rapid development of social science and technology, the demand for oil and natural gas is increasing day by day, and there are more and more anti-corrosion measures for oil pipelines and natural gas pipelines.

ASTM A106 is the standard specification for high temperature service of seamless carbon steel pipes for high temperature applications, primarily in the oil and gas, petrochemical and power generation industries.

Seamless steel pipes have no welds, high pressure resistance, and high precision, and are used in high-pressure and high-temperature situations; welded pipes have welds, are low-cost, and easy to process, and are used in low-cost, high-volume applications.

DIN 2391 is a German industrial standard that regulates the technical requirements and manufacturing processes of seamless precision steel pipes. With its high precision, good surface quality and excellent mechanical properties, this kind of steel pipe is widely used in automotive, machinery manufacturing, hydraulic system and other fields.

Because of its high strength, pressure resistance, corrosion resistance and good processing properties, seamless steel pipe has become an indispensable material in many industries.

ASTM A519 is an international standard for carbon and alloy steel mechanical pipes used to manufacture seamless cold-drawn or hot-rolled mechanical pipes. The standard covers tubes for machining, structural and pressure applications where high strength, corrosion resistance and dimensional accuracy are required.

Straight seam steel pipe is a kind of steel pipe formed by rolling steel strip or steel plate into a tube at a certain Angle, and then welding the two ends through the linear welding technology. Straight steel pipe is widely used in oil, natural gas, electric power, chemical industry and other fields, especially suitable for high pressure, high temperature conditions of the pipeline.

API 5CT H40 casing is a class commonly used in the oil and gas industry and is designed to ensure well integrity and operational safety. Selecting the right casing grade for the application is critical to the performance and life of the well.
