Prefabrication and Spooling

Sigma Composites provides engineering services through our in-house capabilities and in collaboration with our specialized Engineering Partners. Some of the services we offer to our Clients are:

  • Consulting and providing technical advice and review on the design, manufacturing, testing, fitness-for-purpose, and acceptance of composite piping components form various suppliers​

  • Client project representation at Manufacturer or Job Sites

  • Engineering Drawings covering Alignment Sheets, Isometric generation and mark-up, Spool Sheets, and Shop Floor Production Drawings

  • Stress Analysis verification of piping system structural integrity using CAESAR II

  • Surge Analysis verification of internal pressure and unbalanced forces using PIPENET

  • Pipe Support Packages covering primary supports as well as thrust block design

  • Design verification using 3D Finite Element Analysis

Sigma Composites experienced and certified Project Managers are on hand to assist with managing all execution aspects of composite piping projects covering all phases from design to commissioning.

Our team will handle interfacing with the Client and Suppliers Engineers during the design phase, oversee supply chain management of components up to site delivery, and coordinate with the Site Services team for the installation, testing, and commissioning activities.

Project Management

Once a problem is identified, our Engineers will propose the most optimum solution to be promptly deployed to Client site. Our Site Services team is committed to completing the repair work within the required period as defined in the service level agreement of each contract.

Sigma Composites provides prefabricated spools to suit project requirements when the application supports this type of supply such as in-plant piping systems and modular process skids.

 Prefabrication takes place at Sigma Composites yard by certified and experienced bonders. All spools with suitable ends shall be hydrostatically tested before being shipped to the Client site.

Engineering and Technical Support

Sigma Composites provides regular inspection of piping systems that allows monitoring the health of the piping system and the conditions of its components. This enables the identification of possible failure locations for immediate repair or replacement thus protecting Clients from expensive unplanned shutdowns and repairs.


​​Long- and short-term maintenance and service contracts are available providing regular inspection activities covering composite piping and pipeline installations. Our Site Services team employs traditional industry standard as well as advanced inspection and NDT methods to assess the health of the piping system.

A shop fabricated, or pre-fabricated, piping system is delivered to the Client as assemblies or "spools" of pipes and fittings bonded together by shop joints. Fittings, such as flanges, elbows, reducers, tees, and saddles are joined to the pipe in the shop forming these spools that match the routing of the pipeline in the field.

 Supply of prefabricated spools has many advantages as the end result is a more cost-effective fabrication and erection of the piping system. Often 50-90% of all joints can be performed in the shop at a faster rate and at a lower cost when compared to field joints.
