Poly pipe inspection has become critical in the pipeline and process plant sectors over the last few years.
Some of these industries are shifting towards the use of plastics in lieu of steel.
Technoweld have anticipated this significant shift and the increase in use of plastics, particularly high-density polyethylene (HDPE).
Our staff are now trained and experienced in the inspection of HDPE.
Technoweld’s poly pipe inspection service helps the asset owner understand that HDPE joints are sound by ensuring the following are in place:
- A proven bonding procedure
- Qualified and tested bonding personnel
- Random and statistical sampling
- Supervision and inspection records demonstrating the bonding procedure has been followed
Why Is Poly Pipe Inspection Necessary?
Field poly pipe fusion joints are vulnerable to defects due to operator error and the failure to follow the proven bonding procedure specification.
Some of the typical deviations or errors include lack of or inaccurate scraping, misalignment, not adhering to cool times and contamination.
This is where a poly pipe inspection is necessary.
Due to the lack of reliable NDT methods for butt welding and electro fusion of HDPE, direct inspection is the best method for assuring welded joint quality.
Technoweld have the quality assurance knowledge to complete a poly pipe inspection.
We also have the added advantage of having extensive oil and gas experience. Technoweld can assist you to develop a Bonding Procedure Specification (BPS) to suit your project.
Poly pipe inspection ensures that operators are following the proven bonding procedure, reducing the occurrences of operational errors.
