What This Sector Is Up Against
Petrochemical service mixes acid, alkali and salt in one plant, and the line that is fine on Monday can be thinning by the end of the quarter. Stainless and nickel alloy are specified here because the corrosion resistance and oxidation resistance come from the material rather than from a coating that can be damaged.
Pain Points
- Chloride pitting and stress corrosion cracking in hot process lines
- Hydrofluoric acid units where most alloys have no useful service life
- Weld zone attack on site welded spools that cannot be re-annealed
- Shutdown windows that close before replacement material arrives
What Buyers Need
- Grades stabilised against sensitisation for site welded work
- Nickel alloys for the few streams stainless cannot hold
- Matched pipe, fittings and flanges so a spool completes in one delivery
- Mill certificates and third party inspection the plant inspector will accept

From Enquiry to Container
Step 1
Confirm the medium, temperature and chloride level before the grade is fixed
Step 2
Select the stabilised or nickel grade and the matching filler metal
Step 3
Produce pipe and fittings from matched heats where the order allows
Step 4
Arrange third party inspection and issue the mill test certificate
Step 5
Pack for export and load FCL, LCL or bulk at Shanghai
