This round carbon steel pipe listing records cold-rolled and ERW manufacturing references, with hydraulic, drill and oil applications in the title. A519 is also named, but its applicability to the offered pipe must be established through the selected specification and manufacturing records before technical acceptance.
Clarify the manufacturing condition and governing specification
Request the applicable standard edition, material grade, supply condition and documented production route. The ERW table entry and cold-rolled wording should be explained as part of the actual manufacturing sequence. Confirm the relevant scope and inspection requirements rather than assuming seamless manufacture or substituting another standard.
The table identifies non-alloy carbon steel and lists API and ISO 9001 certificate labels. Obtain the actual documents and their scope where required. Those labels alone do not verify certification of the selected product, and the broad API or EMT special-pipe entries do not establish a service approval.
Define hydraulic bore and dimensional requirements
Available length selections are 6 m and 12 m, each paired with a 6–20 mm thickness entry. The table gives a 219–1066 mm outer-diameter range. Specify the exact outside diameter, wall and length combination, together with bore dimensions, straightness and ovality requirements.
Clarify which measurement the stated ±1% tolerance applies to and how acceptance is determined. Hydraulic use may require particular bore finish, cleanliness or further processing; obtain those requirements explicitly. The listing does not establish a finished cylinder bore or a numerical pressure capacity.
Agree duty, preservation and supply confirmation
Provide the medium, pressure, temperature, cycles and mechanical loads for the intended hydraulic, drilling or oil service. Agree tests, material traceability and project acceptance. Non-oiled supply requires suitable storage and preservation arrangements. Confirm selected availability, the listed 8–14-day delivery wording and actual-weight invoicing terms for the specific order.
