ASTM A53 Grade B pipe for distributor and fabrication orders
We manufacture ASTM A53 Grade B ERW pipe for distributor stock and workshop fabrication. Selected Schedule 40 sizes run from NPS 2–8, with full lengths, cut pieces and prepared ends available in the same wholesale order.
ASTM A53 Type E pipe is supplied to the specified wall and finished length, with ends prepared for the joining method on your material list.
ASTM A53 Type E identifies the ERW pipe on a utility or mechanical-service material list. Its longitudinal seam, specified wall and required pipe tests stay with that purchase item. Plain, threaded, grooved and beveled ends are compared under end preparation below.
A recurring pipe size is easier to process when length batches and end conditions stay consistent. Full lengths suit a workshop's own cutting plan; cut pieces reduce on-site saw work when the finished dimensions are already fixed.

The table covers selected ASTM A53 Grade B ERW sizes. Grade, wall schedule and quantity identify the rest of the purchase specification.
These A53 Grade B selections pair each nominal size with its actual outside diameter and wall.

Nominal dimensions follow ASME B36.10M. Acceptance tolerances follow the ordered product specification.
Use the size buttons in the table to add selected dimensions. Add lengths and quantities in the inquiry, or attach your complete list.
Add sizeAdded to your inquiry. You can edit the line below.Enter positive dimensions; wall must be less than half the OD and quantity must be a whole number.Full lengths and cut pieces can have plain, threaded, grooved or beveled ends. We complete the specified end preparation after cutting and check the finished length from the agreed reference.
Square cuts provide a starting face for threaded or grooved pieces. Butt-weld pipe needs the bevel geometry specified for the joint, including the root face where required.
An oil film protects during handling but must be compatible with later painting or welding. For a coating order, the preparation and pipe-end cutbacks belong in the coating scope, rather than being inferred from a black appearance.
Strip forming, longitudinal welding, sizing and cutting are followed by checks of the seam, pipe body and prepared ends.
Rolls form the strip into a round section before the edges are resistance welded. Sizing establishes the finished diameter; cutting produces the ordered lengths.
Inspection covers the longitudinal seam, pipe geometry and the tests required for the ordered A53 manufacturing type and grade.
Material references connect the finished pipe batch to its chemical and mechanical records.
OD, wall and end geometry are checked for the ordered connection, including prepared threads or grooves.
The material certificate and applicable test record identify the actual manufacturing type and ordered grade.
The packing list separates size, length and end preparation so receiving can match each bundle to its order line.
Equal-size pipe is bundled by finished length and end type. Cut pieces stay distinguishable from full lengths even when both use the same diameter and wall.
Thread protectors and end caps reduce handling damage and keep loose debris out of the bore. Bundles rest on supports rather than directly on the loading floor.
Bundle weight and length must suit the receiving equipment. We list package quantities so a distributor can book each size into its own inventory line.
Our quotation separates pipe, end processing and shipment. Production timing is stated for the selected sizes and quantity; vessel transit is a separate part of the delivery plan.
Yes. We price each size separately and show its production or processing minimum. Full lengths and cut pieces remain identifiable within the combined order.
We review fire-protection purchases against the specified pipe standard and required product listings. An ordinary A53 order does not by itself include a UL or FM listing.
Yes. The end types are separate order lines, with the size, finished length and piece count retained for each. This keeps fitting-ready pipe distinct from the pieces intended for butt welding.
Send the actual outside diameter and wall, or the NPS and schedule. We return the matching manufacturing and price scope for that item; the selected Schedule 40 rows do not limit your inquiry to those six sizes.
Compare quotations for the same grade, dimensions, end work and tests. Batch quantity and processing can change the price difference, while a seamless-only specification remains a separate purchasing requirement.
A size list is enough to start. Include quantities and destination; add the required end type if the pipe will arrive ready for a particular fitting.
