Pipe Spool Drawing Services in the USA

We break your piping into fabrication-ready spools. Isometrics, cut lists, and weld maps that your shop can build and your field can install.

Prefabricating pipe in the shop, instead of welding it in the field, is where the schedule and the margin are. Excelize breaks your coordinated piping model into spools your shop can build and your crew can install.

What It Is

What are pipe spool drawings?

A pipe spool is a prefabricated section of piping, built in the shop and installed as a unit. A spool drawing is the instruction set for that piece: the isometric, the dimensions, the materials, and the welds. Excelize breaks coordinated piping models into spools for U.S. mechanical, plumbing, and process contractors, with isometrics and cut lists ready for fabrication.

What We Deliver

What our spool drawing service includes

Spool drawings and isometrics

Each spool drawn as a clear isometric with dimensions and materials.

Cut lists and BOMs

Pipe, fittings, and material lists per spool, pulled from the model.

Weld maps

Shop and field welds identified and mapped.

Spool numbering and tagging

A numbering system your shop and field can track.

Coordinated to the model

Spooled from piping coordinated to the construction model.

QA-checked

Checked against the model and your standards before issue.

Why It Matters

Why prefab spools pay off

Field welding is slow, costly, and weather-dependent. Move that work to the shop and you cut hours, control quality, and protect the schedule. Spool drawings are what make it possible, clear, numbered, and coordinated, so the right piece shows up ready to install.
