Oilfield Plastic BTC Casing Thread Protectors API Standard For Drill Pipe
PP BTC Casing Thread Protectors for Oilfield Pipe Handling
PP BTC casing thread protectors cover casing connections during transport, yard storage and handling before installation. Order the protector against the exact buttress casing connection drawing, nominal casing size and pin or box end. Drill pipe connections require their own matching protectors; a BTC casing designation does not establish drill pipe compatibility.
Specification review: material listed for this product is polypropylene (PP), with grade and service conditions to be agreed. For size enquiries from 2-3/8 to 20 inches, identify the pipe type and connection separately; NC and REG references belong to other connection designs. For this BTC enquiry, submit only the required casing size and BTC connection dimensions for availability review. Protector diameter, depth and engagement length must come from the approved drawing rather than nominal pipe size alone.

Our company
Shanghai Qinuo supplies molded plastic parts and oilfield accessories. This enquiry focuses on PP protectors matched to BTC casing ends, with separate identification for each casing size and end orientation.
Send the casing connection drawing or representative sample, required coverage and storage conditions. Confirm starting engagement, seating and removal before approving the protector for batch production.
For a custom BTC design, agree critical dimensions, PP grade, molding finish and identification marks. Keep tooling and samples associated with the specific connection revision.
ISO 9001 concerns the quality management system. Connection compatibility and any requested impact, ingress or environmental tests should be defined for the ordered protector; an API product certification is not implied.
FAQ
1. Is BTC the same as a drill pipe connection?
BTC refers to a buttress casing connection. Select a protector for that casing connection and end geometry.
For drill pipe, provide its own complete connection designation and drawing instead of ordering a BTC protector by nominal diameter.
2. What should a BTC protector purchase specification include?
a. Nominal casing size and complete BTC connection reference.
b. Pin or box end and the drawing revision used for fit review.
c. Engagement length, seating position and required thread coverage.
d. PP grade, color and storage exposure requirements.
e. Clearance around the casing end and coupling, where applicable.
f. Quantity and packing identified by casing size and end type.
g. Any agreed acceptance tests and sample approval requirements.
3. How can the fit be checked before delivery?
1. Compare the protector with the approved connection drawing.
2. Check starting engagement on the intended casing end.
3. Confirm seating without forcing or cross-threading.
4. Inspect coverage and clearance around the protected thread.
5. Verify removal and inspect the protector for cracking or distortion.
4. What matters during storage and reuse?
1. Keep BTC items separate from STC, LTC, NC and REG protectors.
2. Label each batch by casing size and pin/box orientation.
3. State outdoor exposure and storage duration when selecting material.
4. Inspect for damaged engagement, loose fit and contaminated threads.
5. Reuse only when the protector still meets the agreed fit and coverage checks.
Other oilfield accessories require their own connection, dimension and material specifications.
