Custom Pipe Spooling & Prefabrication Services in Houston, TX

Plant work in Houston runs on tight deadlines. Whether you’re managing a major outage, planning a unit upgrade, or responding to an unexpected failure, delays and misaligned pipe cost serious time and money. Field work isn’t the place to catch errors.

That’s where we come in. Weldit provides custom pipe spooling and prefabrication services across Houston. We craft pipe spools in our shop to your drawings and specs, and deliver them ready to fit, weld, and go. With Houston’s heat, limited space, and strict schedules, our approach saves crews time and keeps jobs safer.

Houston-Focused Prefabrication That Works Where You Work

Every jobsite in Houston has different challenges. One day you’re bending around tight mechanical rooms in downtown buildings. The next, you’re threading pipe through racks at a terminal along the Ship Channel. Each job needs pipe that fits those physical limits—not just the design on paper.

We take your drawings, models, and field info, then break the system into spools that match real conditions. We handle fits, welds, and prep work in a clean, well-equipped shop. When the spools arrive, they’re labeled, organized, and built to install fast and clean.

Construction moves easier when your crews don’t have to measure and cut pipe in the rain or heat. With our spools, they spend less time sorting and more time setting and welding.

Stop Field Welding from Slowing Down Your Build

 Trying to cut and weld pipe in the field slows everything down. Crews juggle permits, fight for space with other trades, and dodge weather delays. Even small issues like wrong-facing flanges or out-of-square joints can throw off your entire line.

Weldit moves that risk into our shop. We cut and assemble with precision fixtures, maintain centerline alignment, and follow approved weld procedures. You don’t waste hours grinding mismatched joints or chasing scrap after a bad cut. You get pipe that fits and stays where it belongs—no second guessing.

Houston jobs come with tough rules and tighter margins. You need less risk, not more. Our custom pipe spooling gives you better odds of finishing on schedule—without cutting corners.

Our Expertise

What You Get with Our Custom Pipe Spooling

Fully Built Spools from Your Design

We start with your P&IDs, isos, and any 3D models. From there, we plan out your system, define spool breaks, and lay out the fabrication process. Our teams support full system installs, tie-ins, replacements, or one-off solutions.

Each spool gets labeled and packaged by line number, install order, or area. Your crews don’t have to dig through a pile of steel to find what they need. It all shows up ready to stage and install.

Materials and Sizes That Fit Your Project

We work with the materials used throughout Houston—carbon steel, stainless steel, and higher alloys for severe conditions. Whether it’s for process service, utilities, HVAC, or water, we fabricate large- and small-bore piping in a range of thicknesses.

Our welders follow both industry codes and your project specs. We apply your fit-up rules, procedures, and inspection plans, so the finished product folds right into your plant’s standard.

More Than Just Pipe—Full System Support

We don’t stop at elbows and straight runs. We prebuild headers, valve assemblies, tees, flanges, tie-in points, and other specialty layouts. Our shop also prepares skids and steel supports when needed.

This approach means your system shows up more complete from the start. Fewer missing parts. Less sorting. Faster builds.

Precision and Welding That Hold Under Pressure

Exact Machining and Fit-Up

Great spooling starts with tight cuts and perfect fits. Weldit uses live tooling, turning, milling, EDM, and drilling machines to get every cut right. We clamp pipe into custom fixtures while building spools, which ensures angles and centers match across the whole project.

Certified Welders and Trusted Procedures

Our welders run GTAW, SMAW, GMAW, and FCAW—what Houston’s plants expect for carbon, stainless, or exotic metals. We keep field repairs low by sticking to proven welding techniques and clean prep.

Inspection and Tested Readiness

You can’t wait until the jobsite to find out something went wrong. We check critical measurements, confirm weld integrity, and prep clean documents at every step. Expect weld logs, heat numbers, drawing sets, and inspection results that help back up your project file with confidence.

Our Approach to Pipe Spooling in Houston

Scope Review and Drawing Review

We study the drawings, line services, schedules, and field limits. We talk through install conditions, tie-ins, and access. That helps us pick the best spool breaks and plan how they’ll move through our shop.

Step 1

Prefab and Spooling Plan

We lay out cut lists, define break points, and build shipping maps for install order and fit-up. Our project manager matches shop flow to your site’s work plan, so material delivery lines up.

Step 2

Build and Weld

We cut, square, and prep each length. Then our welders fit spools with control and measure clearances. We attach flanges, valves, taps, or shoes as needed.

Step 3
Step 4

Inspect, Test, and Log

Each spool gets reviewed for dimension, fit, and weld quality. When pressure testing or other steps are required, we document results and prepare packages for site handoff.

Step 5

Load and Deliver in Sequence

We protect pipe ends, label each spool by zone, install order, and spec, and package by area. Our team delivers right to your Houston jobsite, ready to install from the first lift.
