This P11/P22 steel pipe listing addresses petrochemical refinery enquiries with A335, chrome-moly and high-temperature wording. Its title also says carbon steel, while the table identifies alloy steel. Obtain a precise material definition before adopting either classification or the combined specification for an order.
Resolve material and manufacturing scope for the enquiry
Select P11 or P22 with its required full supply condition and governing document. Request chemistry, properties, treatment and heat traceability records for the offered pipe. The two grade names do not establish equivalence or confirm that both are available in every listed dimensional combination.
ERW is recorded in the title and technique field. Ask how that actual manufacturing route meets the proposed A335 scope, supported by the applicable edition and inspection evidence. Do not declare combined conformity or substitute a different manufacturing route solely to reconcile the source wording.
Specify dimensions and selected inspection criteria
The outside diameter range is 219–1066 mm. Thickness is listed as 6–20 mm, with either 12 m or 6 m length in the two variants. Choose the complete diameter, wall, length and end configuration and obtain confirmation of that specific supply.
Define the dimensional basis of ±1% and the accepted weld, end and geometry inspections for the chosen specification. Confirm round section, cold-rolled surface and non-oiled condition. The EMT option is not represented by a separate variant or qualification record, so clarify it independently if relevant.
Assess the refinery temperature and process exposure
Provide process medium, composition, temperature, pressure, cycling and loading for selected material, joint and rating review. High-temperature wording provides no numerical limit or corrosion guarantee. Agree project testing and material documentation, and verify actual API or ISO 9001 certificate scope and validity where applicable to the proposed supply.
