PREFABRICATION SPOOLS
- PRODUCT DETAIL
Pipe Fabrication Spools
Description
Pipe fabrication spools are prefabricated piping sections manufactured according to isometric drawings and project specifications for EPC piping systems and industrial projects. Fabrication spools are used to reduce site welding, improve installation efficiency and ensure welding quality and dimensional accuracy.
As an Alloy materials supplier, we supply pipe fabrication spools manufactured from stainless steel, duplex stainless steel and nickel alloy materials for EPC piping systems and industrial projects.
Specifications / Standards
Pipe fabrication spools are manufactured according to international piping standards and project specifications.
Typical standards include:
ASME B31.3 – Process Piping
ASME Section IX – Welding Qualifications
ASME Section V – NDT Testing
ASTM / ASME material standards
EN standards where applicable
NACE MR0175 / ISO 15156 where required
Project specifications, drawings and isometric drawings
Fabrication, welding, testing and documentation are performed according to project requirements.
Material Grades
Pipe fabrication spools can be manufactured using various materials including:
Austenitic stainless steel (TP304, TP304L, TP316, TP316L, TP321, TP347)
Duplex stainless steel (S31803, S32205)
Super duplex stainless steel (S32750, S32760)
Nickel alloys (Inconel 600, 625, Incoloy 825, Hastelloy C276)
Carbon steel and alloy steel where required
Material selection depends on project specifications and service conditions.
Size Range
Pipe fabrication spools can be manufactured in various sizes including:
Pipe sizes from 1/2” to 48”
Various wall thickness according to ASME standards
Fabrication spools according to isometric drawings
Prefabricated pipe sections with fittings, flanges and valves
Shop fabricated piping assemblies
Fabrication dimensions and configuration are based on project drawings.
