OCTG & Tubular Handling
Tubing and Casing Couplings
Tubing and Casing Couplings for well construction, production tubing strings and drillstring components, with quotation fields for outside diameter, weight per length, grade, wall thickness, range, connection, drift, end finish, quantity, coating and mill documentation.
RFQ selection reference
Reference fields for quotation comparison. Final values must be confirmed in the signed manufacturer datasheet.
| Parameter | Reference value | Notes |
|---|---|---|
| Size and weight | OD, wall and nominal weight | Use the project tubular schedule |
| Grade and connection | API or proprietary connection | State coupling and special-clearance needs |
| Documentation | MTC, inspection and traceability | Define heat/lot traceability before order |
Product scope
Tubing and Casing Couplings is presented as a quotation-ready equipment family for well construction, production tubing strings and drillstring components. The page is intended to help buyers define a technically comparable request, not to promise one fixed model or universal specification. Final configuration, dimensional fit, pressure or load rating, material, documentation and compliance must be confirmed against the selected manufacturer's signed datasheet and the purchase specification.
Selection basis
The main selection fields are outside diameter, weight per length, grade, wall thickness, range, connection, drift, end finish, quantity, coating and mill documentation. For replacement work, include the installed equipment maker, model, serial number, original part number, clear nameplate photographs and a dimensioned sketch. Similar-looking oilfield parts are frequently non-interchangeable, so appearance alone is not an adequate purchasing reference.
Reference configuration table
The table above lists common RFQ fields rather than guaranteed stock models. Values shown as ranges or options are preliminary screening information. The buyer, supplier and final manufacturer should close every open item during technical clarification before a commercial order is released.
Documents and quality checks
Define the required document package at quotation stage. Typical requests may include a signed datasheet, dimensional drawing, material certificate, pressure or functional test report, NDT report, certificate of conformity, packing list, marking photographs and preservation procedure. Ask for API or other certification only when the specific product and manufacturing facility must hold it; a website reference is not proof of certification.
RFQ checklist
- Product name, equipment model and required quantity
- Operating pressure or load, temperature, media and service environment
- Size, connection, material, tolerance and applicable standard with edition
- Existing part number, nameplate photos, drawings or technical specification
- Required inspection, testing, traceability and third-party witness points
- Delivery destination, Incoterm, requested delivery date and packing method
- Target price or budget range, plus whether technically equivalent alternatives are acceptable
Upload the specification sheet with the inquiry. We will use it to organize the technical comparison and identify clarification points before quotation.
Technical reference trail
These public references support the equipment family and selection context. They do not imply dealership, authorization or a guaranteed order specification.
Frequently Asked Questions
What information is needed to quote Tubing and Casing Couplings?
Provide outside diameter, weight per length, grade, wall thickness, range, connection, drift, end finish, quantity, coating and mill documentation, quantity, destination, delivery target and the required document package. Attach the governing datasheet or drawing whenever one exists.
Are the displayed ranges guaranteed for an order?
No. They are selection references only. The final manufacturer quotation, signed datasheet and purchase specification control the ordered configuration.
Can I upload a specification or replacement-part photographs?
Yes. The RFQ form accepts technical files and photographs. Include a target price when available so unsuitable options can be screened earlier.
