What Is Pipe Fabrication?

Pipe fabrication is the process of cutting, beveling, and welding piping components like metallic pipes, tees, elbows, flanges, reducers, etc. Pipes can be made from various different materials like stainless steel, duplex steel, carbon steel, and other alloys. Pipe fabrication is a critical component of numerous industries.

Piping fabrication is a highly critical activity and complex process requiring a high level of precision, involving hundreds of components and thousands of steps.

You should ensure maximum quality of work in a pipe fabrication facility to maintain the system integrity and minimize accidents.

Where Does Pipe Fabrication Take Place?

Sometimes pipe spool fabrication will occur in an industrial facility, and sometimes a project will need a field construction solution.

The size and scope of the project will determine whether it's more efficient, effective, or appropriate to fabricate pipe in the fabrication shop or on-site.

It's also influenced by other factors, like:

  • Availability of on-site support personnel
  • Required welding facilities and resources
  • Time requirement and availability
  • Scheduling and collaboration with other trades
  • Weather
  • Pipe material and dimensions
  • Access to raw materials
  • Accessibility and safety concerns
  • If the project is for existing or new piping systems
  • Environmental and quality control needs



What Are The Types of Piping Fabrication?

Pipe fabrication work is divided into two groups:

  • Shop Pipe Fabrication
  • Field Pipe Fabrication

Several factors will determine whether pipe material will be fabricated in a shop, in the field, or if both methods will be utilized.

Both shop and field pipe fabrication will be used more often than not.

The type and size of the project, piping material, post-fabrication surface treatment, time requirement and availability, environmental condition, and skilled personnel availability all help determine where projects will take place and the installation processes.

Small-bore pipes, threaded and socket welded pipes are field fabricated.

Butt-welded pipes, pipe bending, modular items are typically shop fabricated.

With the shop pipe fabrication process, pipe fittings and components are assembled with a quality weld to spool assemblies at the pipe fabrication shop.

The spools are labeled with an identifier and transported to the construction site to be installed.

All the assemblies are completed at the construction site with field pipe fabrication.

What's Involved In The Pipe Fabrication Process?

The pipe fabrication process is very detailed from beginning to end, no matter what size project it is.

Engineering information like drawing specifications, design requirements, inspection and testing requirements, and applicable codes and code standards related to the project, are contained in a single document.

This document is called the Pipe Fabrication Specification.

Every pipe and its fittings should be manufactured and assembled according to the spool drawings in the pipe fabrication specifications.

Steel Pipe fabricators also need to consider the size of the assembly for transportation purposes.

It's often helpful to have subassemblies to separate large projects into more manageable elements when transporting piping materials between the shop and the project site, especially when being given a time requirement.

When Pipe Fabrication Specifications are completed, the pipe fabrication process looks like this:

  • Marking: Pipe materials are marked and verified.
  • Tagging: Pipe materials are tagged with paint or a stamp to ensure pipe heat numbers are displayed before cutting.
  • Cutting: Pipe cutting methods like saws, gas torch, grinding, or plasma cutting are chosen according to the type of steel pipes or other metal being used.
  • End preparation: Beveling and fit-ups are completed.
  • Welding: Pipe welding planning ensures that pipes are positioned correctly during the welding process. Welding piping components according to the design documents and customer specifications.
  • Pipe and Fitting Welding: Piping and fittings are supported for a fit-up inspection.
  • Details Marking: Identifying attributes of the piping system, like inspection details, are marked near joints.
  • Heat Treatment: Preheating and post-weld heat treatment may be completed
  • Inspection: Non-destructive testing ensures that all fabrication process steps are complete and meet or surpass the project requirements and codes. If the piping that passes is released for painting or construction. If it doesn't pass must be repaired and reinspected. Piping that is to be painted will be inspected again before being released for construction.


Tools And Equipment used for Pipe Fabrication

Pipe fabricators use various advanced equipment to complete jobs safely and efficiently.

Pipe fabrication companies use equipment designed to handle medium to large-scale projects that is only used in the workshop.

It needs appropriate space, weather protection, reliable security, and complete quality control capabilities.

Many pipe fabrication tasks for small-volume projects and piping spools or those with logistical limitations can be completed in the field.

No matter where the work is done, several essential tools allow steel pipe fabricators to create the complex precision piping systems that surround us.

 The widely used equipment is listed below:

  • Chain Clamps/ C Clamps
  • Pipe Fit-up Tools
  • Pipe Purging Equipment
  • Pipe Cutting and Bevelling Equipment
  • Torque Wrench/Adjustable Wrench/Combination Wrench/Hammer Wrench
  • Flange Alignment Tools and Pins
  • Pipe Jacks
  • Adjustable Pipe Rollers
  • Welding Machine
  • Pipe Rigging and transport equipment
  • Center Punch
  • Compass/Contour Marker
  • Pipe Threader
  • Fork Lift
  • Grinder
  • Wraparound Tapes
  • Hydraulic Crane/Tower Crane
  • Pipe Bending Machine, etc
