PP Plastic Screw Tubing Thread Protectors REG IF HT FH API Standard

1. What information distinguishes REG, IF, HT and FH orders?
Provide the complete connection designation and size, drawing revision, end orientation and quantity. Abbreviations without dimensions are insufficient for fit approval.
Where HT appears on an existing specification, send its full meaning and a mating drawing or sample rather than substituting another connection code.
2. How should pin and box protectors be specified?
a. List pipe-pin and mating-box ends separately.
b. Assign a distinct part number to each connection and end orientation.
c. Define engagement geometry, required coverage and acceptable clearance.
d. Review installation and removal on the actual mating part.
e. Specify identification marks and packaging labels.
f. State PP grade, colour and exposure conditions.
g. Agree sample and inspection requirements before production.
3. Does a connection code establish an API rating?
1. A connection reference identifies the intended mating geometry; it does not establish certification.
2. State the applicable specification and revision if conformity is required.
3. Define dimensional and handling acceptance criteria for the protector itself.
4. Provide any required tests and inspection documentation with the enquiry.
5. Approve each configuration against its own mating drawing or sample.
4. What should a mixed-connection purchase order contain?
1. Separate quantities for every size, connection and end orientation.
2. Approved drawing revision and sample reference.
3. PP grade, colour and marking requirements.
4. Packing labels that prevent mixing similar-looking protectors.
5. Delivery and inspection requirements agreed for the order.
For other oilfield accessories, specify their own model and mating dimensions separately.
Send the connection list, drawings or original samples for a configuration-specific quotation.
