Heavy Duty Plastic Drill Pipe Thread Protectors , OCTG Screw Protectors Black
PP Drill Pipe Thread Protectors for Handling and Storage
These polypropylene (PP) drill pipe thread protectors cover tool joint connections during transport, rack storage and handling before use. Match each protector to the full connection designation, pin or box end and tool joint drawing. Specify handling duty through agreed coverage, retention and impact checks rather than treating a heavy-duty description as a tested rating.
Connection references include NC26, NC38, NC50 and selected REG sizes from the original product range. Confirm availability against the required tool joint drawing. The broader nominal pipe size list from 2-3/8 to 20 inches and BTC, STC and LTC casing references do not define a drill pipe protector fit. State thread geometry, engagement length and shoulder clearance for the ordered design.

Our company
Shanghai Qinuo supplies molded plastic parts and oilfield accessories. For PP drill pipe protectors, provide the tool joint connection schedule and the intended transport and storage conditions.
A drill pipe enquiry should identify pin and box quantities separately. Review thread engagement, body clearance and the area to be covered on each end before confirming production.
Custom protector tooling should follow the approved tool joint drawing. Agree PP grade, molded dimensions, identification marks and sample fit checks for each connection.
ISO 9001 applies to the quality management system. Any requested impact, retention or environmental performance must be defined and verified for the ordered design; product-specific API certification is not implied.
