Anson steel tubes for transportation of flammable media - line pipes

Tianjin Anson International Co., Ltd steel tubes for transportation of flammable fluids are produced by hot rolling. The semi-finished product used for these tubes is continuously cast bloom. This group of tubes is mainly set for high pressure gas pipeline to deliver gases, oil and other flammable fluids in the mining, chemical and energy industry. Line pipes are made from carbon and alloyed steel. Overview of the dimensional standards and technical-delivery conditions by which line pipes are manufactured and supplied is shown in a separate overview.

Line pipe - dimensions

The outside diameter of the tubes for transportation of flammable fluids ranges from 0.405 to 4.5 inches (10.3 to 114.30 mm), wall thickness from 0.068 to 0.531 inches (1.7 to 13.5 mm). More detailed dimensions are shown in tables and they are according to the EN standards and API standards. Preferably the tubes are supplied as hot rolled. Dimensions 0.405 inches, 0.540 inches, 0.675 inches and they are supplied as cold drawn

Line pipe - types of steel.

Tubes for transportation of flammable fluids are made of the following steels, according to EN 10208-1: L210GA, L235GA, L245GA, L290GA, L360GA, according to EN 10208-2: L245NB, L290NB, L360NB, L415NB and according to API 5L: Grade A, Grade B, Grade X42, Grade X46, Grade X52, Grade X60. Additional types of steel (according to DIN 2470-1/1629 and 2470-2/17172 and UNI 7088) together with its chemicals composition and mechanical properties are shown in a separate overview. Steel is made in the electric arc furnace and it is fully killed.

Line pipe - delivery condition and surface

Usually the tubes are supplied as hot rolled. Only tubes with DN 6 -10, perhaps tubes of other dimensions are supplied as cold drawn and after forming they are heat treated. This is done as per precious agreement. The tube surface meets corresponds to the means of manufacturing.
