  ERW

This ERW welded carbon steel pipe enquiry covers oil, hydraulic fluid and gas conveyance. The listing records round, non-alloy steel with cold-rolled processing and non-oiled supply. Its ASTM reference remains generic, so the specific material and acceptance requirements must be agreed for the actual order.

Define the fluid and connection requirements

Identify the transported medium and its composition, contaminants and operating conditions. Provide pressure, temperature, cycling and external loads for assessment of the selected pipe and joints. Oil, gas and hydraulic labels do not establish identical compatibility requirements or a common allowable pressure.

Specify the required end arrangement, joint preparation and inspection criteria. Hydraulic applications may also need defined bore finish and cleanliness. Those details should be stated explicitly; the catalogue does not establish a honed bore, sour-fluid qualification or a particular finished hydraulic supply.

Confirm the actual specification and dimensional selection

Ask the supplier for the numbered ASTM specification, edition, grade and condition applicable to the offered pipe. Obtain chemical, mechanical, ERW weld and traceability records, and clarify the cold-processing sequence. A standard used for another product should not be imported into this enquiry.

The variants offer 6 m or 12 m length with a 6–20 mm thickness entry, alongside a 219–1066 mm outside-diameter field. Select one exact diameter, wall and length combination. Define the dimension covered by ±1%, the measurement method, straightness and ovality limits and actual availability.

Agree preservation and inspection before delivery

Cold Rolled does not specify a protective coating. Agree storage, preservation and any required treatment for non-oiled supply. Request certificate documents and scope where API or ISO 9001 evidence is required, then confirm tests, project acceptance, actual-weight invoicing and the listed 8–14-day delivery wording for the selected pipe.
