Why do gas pipelines use seamless steel pipes?

Update time : 2023-10-11 15:39:31

　　1. Seamless Steel Pipe has better pressure resistance

　　Compared with welded pipes, seamless steel pipes can withstand greater pressure because there are no welds on the inner wall of the pipe, thereby ensuring the stability and reliability of the pipeline.

　　2. Seamless tube has better corrosion resistance

　　Seamless tubes have a smooth surface, stable molding, and good corrosion resistance. However, welded steel pipes require the addition of welding materials during welding, which may cause various defects in the welding joint and make them susceptible to corrosion and other factors, causing problems such as pipeline leakage.

　　3. Seamless tube processing with high precision

　　During the production process of seamless tubes, due to the higher production pressure and temperature, a uniform, weld-free organizational structure can be formed inside the material, thereby greatly improving the production process and processing accuracy, and is more suitable for manufacturing high-quality steel tubes. Strength pipe.

　　To sum up, the use of seamless tubes in gas pipelines is to ensure the high strength, corrosion resistance and stability of the pipelines, thereby ensuring the safety of gas transmission.

ASME B31.3 Steel Pipe Pressure and Wall Thickness Calculation

Oct .29.2026

　　The ASME B31.3 wall thickness of a steel pipe is directly related to its pressure-bearing capacity. Generally, the greater the wall thickness, the greater the pressure the pipe can withstand. this relationship is not a simple direct proportion; it requires precise calculation using standard formulas.Shengtian Group will introduce the most commonly used wall thickness calculation formulas in the American and Chinese standard systems, as well as the key parameters to consider during the calculation process.

ASME B36.10 / B36.19 Steel Pipe Dimensions & Sizes Chart

Oct .27.2026

ASME/ANSI B36.10 & B36.19 Steel Pipe Dimension 3 Characters:A completely description for steel pipe dimension includes outer diameter (OD), wall thickness (WT), pipe length (Normally 20 ft 6 meter, or 40 ft 12 meters).

EN 10219 S460MH Steel Pipe: Selection & Application

Oct .22.2026

EN 10219-1 is the European standard for cold-formed welded structural hollow sections. S460 is the high-strength grade within this standard. The “S” stands for structural steel, “460” means a minimum yield strength of 460 MPa, “M” means thermomechanical rolling, and “H” means hollow section.Shengtian Group this guide covers S460MH under EN 10219-1, as well as S460NH and S460NLH under EN 10210. You will find material data, size ranges, selection logic, driving suitability, and certification requirements.

How to Choose Carbon Steel Pipe Size?

Oct .20.2026

When selecting carbon steel pipe (CS Pipe) size, pipe diameter (NPS/DN), wall thickness (Schedule Number), and pressure rating are three interrelated core parameters. Their selection requires comprehensive calculation based on the system design pressure, flow rate, and medium characteristics.
