Thread Both Ends Pipe Nipple

1.Before any steel pipes leave our facility, our team carries out practical inspections step by step.

2.We first check the raw steel we receive. We review material certificates and chemical analysis reports, so we know the base material is what it should be.

3.Our workers manually measure outer diameter, wall thickness, pipe length and pipe‑end condition piece by piece. Every pipe gets a close visual look; we watch out for cracks, scratches and any surface damage that shouldn't be there.

4.According to different product specifications, we conduct hydrostatic test, hardness test and non‑destructive inspection as required.

5.We save inspection records for each batch. Should you require test documents for your project, just let us know and we will send them over.
