3 / 8 * 0.035 合金 825 Downhole Chemical Injection Tubing ASTM B704

Baosheng offers a variety of duplex stainless steel, super duplex stainless steel welded and seamless tubing, depending upon the properties the tubing is required to exhibit. Other alloys and sizes are also available upon request. Duplex stainless steels (named for their austenite and ferrite compositions), has greater yield strength than austenitic stainless steel.

 

It is mainly used in flue gas desulfurization spray towers, reverse osmosis seawater desalination equipment and pumps, chemical reaction kettles and pipelines, heat exchangers using seawater media, crude oil separation distillation towers and metal fillers, marine oil and gas extraction equipment as well as scrubber drums, pressure rollers, tanks, 管道, 等. in the pulp bleaching systems.

We have a mature quality control system to ensure a 100% qualified delivery rate:

Chemical composition analysis

Tensile testing

硬度

Flattening

燃烧

Hydrostatic testing

Eddy current testing

Our products have complete specifications and can meet all working conditions. Our outer diameter range of Alloy 825 tubing is from 1/8to 1/2″. All dimensions and corresponding parameters are listed in the table below, we can also customize it according to customersspecial requirements.
