Pipe welding & fabrication calculators

Quick, mobile-friendly tools for pipe fitters and welders in the field. Free to use, no signup, no math tables.

Pipe Weight Calculator

Weight per foot and total weight for any steel pipe. Enter OD, wall thickness, and length — get pounds. Handy for rigging and load planning.

Enter wall thickness, bevel angle, and land to get bevel depth, width, and face length for consistent weld prep.

Cut angle and cutback for mitered pipe elbows. Enter OD, turn angle, and number of pieces — get your layout marks.

Set, roll, and fitting angle in — true offset, travel, and run out. Decimal and fraction results with a visual of the offset box.

The classic set / travel / run triangle for 45s, 22.5s, and more. The most-used calculation in pipefitting, instant and mobile-friendly.

ASME B16.9 takeouts for 90 and 45 elbows, long and short radius, plus cut lengths between fittings. Real table values, not rules of thumb.

Estimate weld metal and rod needed per pipe joint by size, wall, and process. Useful for bidding pipeline jobs.

These tools are free because we make the TNB roll out wheel — a truck-mounted pipe positioner that lets you weld solo, in the field.
