Duplex Stainless Steel Pipe and Tube
Property:
The duplex material is a kind of ferrite-austenitic duplex stainless steel, which is intergrated conducived properties both of ferrite and austenitic and provided with higher intensity as well as tenacity.
On the base of high content of chrome and molybdenum, the duplex material is endowed with all sorts capability of corrosion.
The duplex material possess low heat expanding while its conductivity is higher than austenitic stainless steel.
The duplex material owns good jointing property.
Product major application:
Exchangers and pipelines used in the equipment of petroleum production, processing and transportion/Crude oil, natual gas and sea water desalination/chemicals processing and transportation equipment/chloride solution processing treatment and transportation/chemical tankers, oil tankers and water processing pipelines.
