Precision Steel Tube Production and Precautions

Precision steel tube is a kind of steel tube with high precision and high surface quality, which is widely used in petroleum, chemical, electric power, automobile and other fields. Due to its high pre

High-Pressure Seamless 12Cr1MoVG Tube: Heat Treatment and Service

High-pressure seamless 12Cr1MoVG tube is produced by hot working a solid round, so the pressure boundary carries no weld seam. This article covers the melting and rolling route, the normalising and te

Japanese standard seamless pipe standard

Japanese standard seamless pipes refer to seamless steel pipes that comply with Japanese industrial standards and are widely used in petroleum, natural gas, chemical industry, shipbuilding, nuclear en

European standard seamless pipe standard

The standards followed by European standard seamless pipes mainly include EN 10210, EN 10216 and EN 10219. EN 10210 is used for manufacturing non-alloy seamless steel pipes for structures, EN 10216 is

Welding Specifications for Thermal Pipelines

Thermal pipeline welding follows a standard three-stage process: argon-arc bottoming, interlayer filling, and cover welding.

Natural gas pipeline structural characteristics

Natural gas pipelines refer to pipelines that transport natural gas (including associated gas produced in oil fields) from mining sites or processing plants to urban gas distribution centers or indust

How to install and connect natural gas pipelines
