Plastic injection molded drill pipe thread protector for sale
Injection-Molded Plastic Drill Pipe Thread Protectors for Sample Approval
Injection-molded plastic drill pipe thread protectors cover matching tool-joint threads during transport and storage. Select HDPE or ABS as an approved material grade for the item, then match the molded engagement geometry to the connection drawing. The material alternatives are not automatically interchangeable.
Sample approval should establish fit, seating, coverage and removal on the intended pin or box end before production quantities are ordered. Include the complete connection designation and drawing revision so the sample can be identified again in later batches.
All-plastic and metal-plastic composite designs require separate specifications. For this molded plastic selection, agree dimensional tolerances and inspection points on the actual protector. Appearance, a shared size label or a material-family name alone cannot establish fit or handling performance.
Connection references include NC26, NC38, NC50 and REG designations, subject to connection drawing and availability review. The broader 2-3/8 to 20 inch pipe range and BTC/STC/LTC casing references describe separate items. For the selected drill pipe protector, specify thread profile, engagement length, seating clearance, coverage, polymer grade and quantity.

Our company
Shanghai Qinuo supplies molded plastic components and oilfield accessories. For injection-molded drill pipe protectors, link sample approval to the selected connection and material specification.
Provide the pipe-end drawing, protector requirements and an identifiable reference sample where available. Agree which dimensions and fit checks will be used for approval.
Review tooling against the current drawing revision before production. Record approved color, markings, packaging and inspection points for subsequent batches.
ISO 9001 applies to quality management. Any additional exposure or handling tests should state the method, conditions and acceptance criteria for the ordered material and geometry.
