5 Process Pipe Welding Techniques for Industrial Construction

Posted on | Leave a Comment

What Is Process Piping?

Process Piping is critical to the operation of many manufacturing and processing facilities. Typical plumbing systems are used to move liquids and gases for heating and cooling processes or are used to move water and waste through a building. However, process piping is used to convey liquids, chemicals, fuels, gases and other raw materials used in manufacturing enterprises into an end product.

Process piping consists of any piping and components not part of the facility’s mechanical systems. These piping components move, mix, distribute, and control the flow of fluids commonly used in many industries, such as the manufacturing of semiconductors, chemicals, paper processing, petroleum products pharmaceuticals, and textiles. These systems require the skill and attention of an expert to ensure they are installed and maintained properly and provide flawless operation.

Base Construction has over two decades of experience with process piping. We are experts in general, specialty, industry-specific, and site-specific safety services for manufacturing facilities that utilize process piping as a primary part of their production processes. Our team of highly qualified pipefitters ensures all applicable code requirements are met and provides clients with a diverse range of process piping services, including:

  • Pipe routing design and implementation
  • Pipe design support and installation
  • Piping and instrumentation diagram development and implementation

  • Pipe insulation and heat tracing

Process Piping Welding Techniques​

Butt Welding

Butt welding is one of the most commonly used welding techniques and can be performed either manually or automatically. Butt welds are used to join pipes together as well as joining them to fittings, flanges, valves, and other equipment. This welding technique is widely used in applications that require a high-quality weld and is usually inspected by X-ray to ensure the quality of the weld.

Socket Weld Threaded

A socket weld is primarily used for small diameter pipes and is a joint used to insert the pipe into a recessed area of a flange, valve, or fitting. Socket welded joints provide high leakage integrity and great structural strength and are one of the best techniques for most mechanical joining methods.

Soldered End

Soldered end joints attach components with the use of a metal filler or solder. The solder has a lower melting point than the adjoining metal, and the joint is created by melting the solder into the joint, permanently attaching the components.


A flange joint connects pipes, valves, pumps, and other equipment to a piping system with the use of flanges welded or bolted together with a gasket between the components to prevent leakage. Flange joints provide easy access for cleaning, inspection, or modification.

Mechanical Joint Fusion

A mechanical joint is a compression joint designed for underground connections of pipes, valves, and fittings. Mechanical joints are both socket and butt joints and allow for some deflection at the joint to accommodate slight misalignments, due to installation issues, while still maintaining a seal under pressure.

Hydraulic Coupling

A fluid coupling or hydraulic coupling is a device used to transmit rotating mechanical power from one shaft to another through the acceleration and deceleration of hydraulic fluid. Hydraulic coupling is based on hydro-kinetic principles and requires that the output speed is less than the input.

  • Slip-on Glued
  • Grooved
