One-Minute Overview

Seamless pipe delivered with weld bevels already cut on both ends.
Bevel angle 30 degrees per ASME B16.25, with compound bevels on thick walls.
Sizes 1/2 to 24 inch, schedules Sch 40 to XXS, carbon and alloy grades.
Protected with end caps so the bevel face survives shipping and storage.

A bevel end seamless pipe leaves the mill ready to butt weld. The end is machined to a weld preparation — usually a 30-degree bevel with a small land, per ASME B16.25 — so the welder fits up without cutting the prep in the field. On heavy wall schedules the bevel goes compound, with a steeper second angle, so the root pass is deposited in controlled beads instead of one oversized pour. Carbon and alloy grades are available, from general line pipe grades to chrome-moly for hot service. Sizes run 1/2 to 24 inch, Sch 40 to XXS.

Bevel geometry is what makes fit-up fast. The standard 30-degree angle, a root face of a couple of millimetres and a clean land give the welder a gap he can control. Mismatched OD and a bellied bevel are the usual complaints, so check the first and last pipe of every bundle. On thick walls, order the compound bevel your welding procedure expects; a straight bevel on a heavy wall forces a wide groove and a slow, expensive fill.

Protect the faces. Bevels travel with plastic caps and end protectors because a chipped or rusted bevel means grinding before every weld. Store the pipe capped and off the ground, keep alloy grades segregated and dry, and weld with the preheat and consumables the grade requires. Where the code asks for it, add radiographic or ultrasonic examination to the butt welds and keep the traceability chain — heat number on the pipe, weld map on the spool — intact from goods receipt to hydrotest.

FAQ

Q1. What bevel preparation does ASME B16.25 define?

ASME B16.25 defines butt welding end preparation: bevel angle, root face and bore alignment across the wall thickness range. Commonly the bevel is 30 degrees with a small land, with compound bevels on heavy walls. The exact geometry should match the qualified welding procedure for the grade and thickness you order.

Q2. Why pay for factory bevels instead of cutting them on site?

Time, consistency and cleanliness. A factory bevel is machined square and uniform, so fit-up is quicker and the welder works with a known geometry. On site, beveling means more cutting, more grinding and more chances to nick the pipe. Caps are cheap insurance either way.

Q3. What usually ruins a perfectly good bevel end?

Forklifts, rain and optimism. Bevels chip when bundles are dropped, corrode when stored uncapped, and get ground flat when they arrive mismatched. Caps, dunnage and a quick check at receiving prevent most of it. The welder will thank you — probably with fewer complaints.

Q4. What's the minimum I can order?

Standard flange insulation gasket kits start at one set, and standard gaskets, studs, washers and sleeves start at one piece. Kits made to your drawing or for a non-standard bolt pattern are quoted individually, because the minimum really depends on the material and the tooling involved.
