Equipped to meet the demands of today’s offshore and power generation industries
Weld Surfacing and Inlay QAWT has developed an extensive range of procedures and techniques for weld inlay applications for the Offshore, Petrochemical and Power Generation industries. They include computer controlled hot wire TIG inlay of bores from 40mm diameter and up to 1.5 metres long. Dedicated hot wire TIG pipe cladding machines, automatic submerged-arc and Electro-slag strip cladding are available to complement QAWT’s full range of inlay capabilities.
Weld inlays can be carried out on components for final machining by customers or within our extensive machining facility. NDT, post weld heat treatment and final certification are available to meet customer requirements and specifications.
Flowspool & Pigging Loop Manufacture As a leading supplier of flowspools to the offshore oil industry QAWT combine a wide experience of the industry’s requirements to provide a complete project management service embracing all aspects of production and testing to certification and documentation. Flowspool manufacture is carried out by dedicated Induction Bending machines with capacity induction coils used for bending within 2’ - 8”, 2” - 18” and 10” - 30”. All flowspools are jig built to close industry tolerances. Over 400 approved welding procedures are also available for an extensive range of materials.
QAWT also have extensive bore and RTJ inlay capacity expertise using computer controlled Hot Wire TIG cladding machines. NDT, post weld heat treatment and hydrostatic pressure testing is available to meet customer specification and API codes.
In-line & Flanged WeldLink joining of PE lined water injection pipe ™
WeldLink™ was an innovation by British Gas for a method of joining PE lined pipe. QAWT was invited by British Gas to develop the procedures and techniques for this patented weld joint. Having manufactured WeldLinks™ for global customers, QAWT are now the nominated world-wide manufacturer for the Licensee. QAWT continue to develop new and innovative procedures to meet global customer demand.
WeldLinks™, along with Compression Rings form an integral part of a jointing system for connecting PE (Polyethylene) lined Water Injection pipe and are a are a cost effective alternative solution to Duplex or Inconel clad pipe for Water Injection Pipelines
