Steel Pipe Supplier with Welding and Fabrication Services: From Raw Pipe to Installed Spool – PetroleumPipes

Some Pipe Suppliers sell you pipe and wish you luck. Others sell you pipe plus fittings and hope you can put it together. We go further — we supply raw pipe, fabricate it into spools, weld it to your specs, and deliver it ready for installation.

Let’s talk about what a full-service pipe supplier brings to your project.

**What We Mean by “Full Service”**

Here’s the scope of our welding and fabrication services:

– **Pipe supply**: carbon steel, stainless, alloy — seamless and welded
– **Fitting supply**: Elbows, tees, reducers, flanges, caps
– **Cutting**: Saw cutting, plasma cutting, oxy-fuel cutting
– **Beveling**: Pipe end preparation for welding
– **Fit-up**: Aligning pipe and fittings for welding
– **Welding**: GTAW, SMAW, FCAW, SAW — per your WPS
– **NDE**: RT, UT, MT, PT — third-party inspection available
– **coating**: Paint, FBE, galvanizing after fabrication
– **testing**: Hydrostatic testing of fabricated spools

**Why Choose a Supplier Who Fabricates?**

When you buy raw pipe and hire a separate fabricator, you’re managing:

– Two suppliers with different schedules
– quality gaps between pipe and fabrication
– transportation of raw pipe to the fab shop
– Coordination headaches when something doesn’t fit

When you buy fabricated spools from us:

– **One supplier, one schedule**: We manage the whole process
– **Integrated quality**: Pipe and welds inspected to the same standards
– **Less handling**: Raw pipe goes in, finished spools come out
– **Faster delivery**: No waiting for multiple suppliers to coordinate
– **Single accountability**: If there’s an issue, we own it

**Our Fabrication Shop Capabilities**

We operate iso–certified fabrication shops with:

– **Cutting equipment**: CNC saws, plasma cutters, oxy-fuel torches
– **Beveling machines**: Pipe end prep up to 48″ OD
– **Fit-up tools**: internal line-up clamps, external clamps
– **Welding equipment**: TIG, stick, flux-core, submerged arc
– **Positioners**: Pipe rotators, turning rolls for efficient welding
– **NDE equipment**: X-ray, ultrasonic, magnetic particle, dye penetrant

**Welding Qualifications and Standards**

Our welders and procedures are qualified to:

– **ASME Section IX**: Welding procedure and performance qualification
– ** API 1104**: pipeline welding standard
– **AWS D1.1**: structural welding code
– **customer–specific WPS**: We weld to your procedure

**Quality Control Throughout Fabrication**

Every fabricated spool goes through:

1. **Incoming inspection**: Pipe and fittings verified against spec
2. **Fit-up inspection**: alignment, gap, root face checked before welding
3. **In-process inspection**: Visual inspection of each weld pass
4. **Final inspection**: dimensional check, visual weld inspection
5. **NDE**: RT, UT, MT, or PT as specified
6. **Hydrostatic test**: Pressure test of completed spool
7. **Coating inspection**: If coated, thickness and adhesion verified

**Deliverables**

When fabricated spools ship, you receive:

– **As-built drawings**: Red-lined drawings showing actual dimensions
– **Weld maps**: Location and ID of every weld
– **Welder qualifications**: Certificates for each welder
– **WPS and PQR**: Welding procedure specs and performance records
– **NDE reports**: RT films, UT reports, MT/PT reports
– **Hydrostatic test reports**: Test pressure and results
– **Coating reports**: If applicable

**Project Experience**

We’ve supplied fabricated pipe spools for:

– ** Oil & gas**: Pipeline tie-ins, platform piping, compressor stations
– **Power generation**: boiler tubing, steam lines, cooling water
– **chemical plants**: Process piping, utility systems
– **Water treatment**: Intake and discharge piping, process lines
– **mining**: Slurry lines, tailings piping, process water
