P110 in the published grade list
P110 is one of the standard grades in the factory's published list, alongside J55, K55, N80 and L80-1; which sections a design assigns to it is the design's decision, taken against that section's load cases. The chromium grades are listed separately from the carbon grades.
The catalogue carries a concrete P110 artefact worth noting: a 13-3/8 in P110 BTC casing coupling listed as a stock entry. That entry shows P110 is a working grade in this factory's coupling programme, not a paper grade, and it names the thread form for that coupling: BTC. Beyond that entry, this page makes no size claim for P110: the grade is named in the published grade list and the sizes are published separately, so a P110 line is specified by size, weight and the thread form the design states — STC, LTC, BTC or a premium pattern — and the combination is confirmed in the quotation.
What changes when you order P110
| Item | P110 practice | Reason |
|---|---|---|
| Thread choice | The form the design states, per line | No default form is assumed for P110 |
| Couplings | The form the design states, stated per line | A weaker coupling caps the whole string |
| Inspection documents | Agree scope and PSL before production | Scope confirmed in the quotation for the order |
| Handling | Protectors on; marking as confirmed for the order | Threaded ends are precision surfaces |
Price follows the same logic: P110 is quoted per specification — size, weight, grade, thread, range and quantity — and never from a generic casing price list. The weight and drift selection guide is worth reading alongside this page: where a design weighs wall thickness against grade, the trade between the options is a collapse, tension and running-weight calculation made by the design, not a price-per-tonne comparison.
P110 and the rest of the string
A P110 section sits within a wider programme. The sections around it carry the grades their designs name; couplings, pup joints and crossovers for the section are named on their own lines — see casing pup joints. Send the whole programme with the enquiry, and ask for grade transitions to be treated explicitly, line by line, in the quotation. Ask for MOQ, packing and lead time to be confirmed for the programme in that written quotation.
How does P110 sit in the published grade list?
P110 is one of the standard grades in the published list, alongside J55, K55, N80 and L80-1. The chromium designations are listed separately; published service data on this site exists only for the 13Cr series, and no duty is assigned to the other chromium grades. Which grade a section takes is set by the design.
Do you hold P110 products in stock?
A 13-3/8 in P110 BTC casing coupling is listed as a stock entry in the catalogue. Ask for the current availability of your size and grade to be confirmed in the quotation — stock moves, and no schedule should rest on an unconfirmed stock assumption.
Can P110 casing be ordered with premium connections?
Name the connection in the RFQ, and ask for premium thread processing on the P110 line to be confirmed for the size in the quotation.
