Quality Control for Pipe Products

Pipes are necessary for a variety of liquid systems including, water, sewage and reuse installations. Pipes are essential components for dependable fabrication and it’s critical that any weak or failure-prone pipes are detected and removed before they are introduced at work sites.

Pipes come in various types of materials, enabling them to cater for a range of intended purposes, mainly including:

  • Cast Iron Pipes/ Ductile Iron Pipe
  • Asbestos Pipe
  • PVC Pipes
  • Galvanized Steel (GI) Pipes
  • Concrete Pipes
  • HDPE Pipes

The Importance of Quality Control for Pipe Products

Quality control for pipe products is important for safety, the economy and regulatory compliance. Many variables should be taken into consideration during the quality control process including, the dimensions, hardness and edge condition of the incoming materials, the power delivered to the welding unit, as well as the condition of tooling surfaces, bearings and any other components.

Pipe failure may result in loss of product and cessation of production while the pipeline is repaired. A pipe failure may also result in costly cleanups and waste remediation’s. 

The inspection process for pipe products is aimed to carry out independent assessments of pipe products, and evaluate the quality of workmanship and dimension condition, including:

  • Factor/supplier audit
  • Development and review of inspection and testing protocol
  • Pre-production inspection (PPI), during production inspection (DUPRO), pre-shipment inspection (PSI)
  • Loading / unloading supervision (LS / US)
  • Production monitoring
