Galvanized pipes for oil and gas

Galvanized steel pipes, specifically known as Hot-dip galvanized pipes, play a significant role in the extraction, transportation pipelines, and storage of oil and natural gas. These Galvanized pipes for oil and gas are crucial in various stages of the industry. In oil well pipelines, the Galvanized steel tube's layer effectively resists the erosion of corrosive substances in the strata, preventing chemical reactions between the inner wall of the pipeline and the transported oil and gas, thereby avoiding corrosion perforation of the pipeline. In the transportation pipeline system, the galvanized layer enhances the corrosion resistance of the steel pipe, extending the service life of the pipeline. In oil tank facilities, Galvanized steel pipes are used for the connection of auxiliary pipelines and the supporting structure of the tank body, effectively resisting the corrosive gas erosion of oil and gas.

Galvanized steel pipes are manufactured in various steel grades to meet different industry standards and performance requirements.
Here are some popular steel grades for galvanized steel pipes:

ASTM A53: This is a standard specification for pipe, steel, black and hot-dipped, zinc-coated, welded and seamless. It is commonly used for general construction and structural purposes.
ASTM A120: This specification covers zinc-coated (galvanized) welded and seamless steel pipe for use in gas or water distribution and other applications where the pipe is subject to external corrosion.
ASTM A123: This specification covers zinc (hot-dip galvanized) coating on iron and steel products, including steel pipes.
ASTM A153: This specification covers zinc coating (hot-dip) on pipe and tubular shapes made of zinc-coated steel.
ASTM A106: This specification covers seamless carbon steel pipe for high-temperature service in NPS 1/8 to NPS 48.
ASTM A139: This specification covers electric-resistance-welded steel pipe used for threaded and coupled applications.
BS 1387: This is a British Standard that specifies the requirements for galvanized and non-galvanized mild steel tubes and tubes for scaffolding and forms.
DIN 2440/2441: These German standards cover the requirements for galvanized steel pipes, including dimensions, tolerances, and mechanical properties.
EN 10255: This European standard specifies the requirements for hot-dip galvanized coatings on fabricated iron and steel products.
JIS G 3141: This Japanese Industrial Standard covers general requirements for galvanized steel pipes.
GB/T 3091-2015: Welded Steel Pipes for Low Pressure Fluid Conveyance" is a Chinese national standard that specifies the requirements for welded steel pipes used for the conveyance of low-pressure fluids. This standard is applicable to steel pipes that are intended for the transportation of water, gas, air, and other low-pressure fluids.
