Product Description

Wholesale Drill Rod for Directional Drills Drill Pipes #600 D24*40
 

Quality Control

Our quality team's work begins by ensuring a consistently high standard of raw material: checking every batch on delivery against the technical team's strict criteria for dimensional accuracy and steel chemistry. Once approved for production, every item of material is issued a work number that allows us to track it through every subsequent step of the manufacturing process. The completed product is finally issued and stamped with a serial number that enables 100%
traceability of all that manufacturing data.


We break open samples from every batch of pipe to check the steel's mechanical properties are up to S135
standard. Just as importantly, our trained QC staff carry out 100% physical and non-destructive inspections of every forged end.This ensures there are no internal cracks, sharp transitions or underfills - any of which could lead to rapid propagation of stress cracks. No pipe is released to market without a quality report verifying compliance with all destructive and non destructive testing criteria.
