Product Q&A

Q:What industry standards do your casing couplings comply with?

Our couplings are fully manufactured in accordance with API Spec 5CT (for material and dimensional requirements) and API Spec 5B (for threading specifications). We also operate under an API Spec Q1 certified quality management system, ensuring consistent, reliable performance for oilfield applications.

Q:What types of connections/threads do you support for couplings?

We support both standard API threads (including STC, LTC, BTC) and authorized premium connections . All premium threads are produced with full authorization, ensuring 100% compatibility and interchangeability with premium casing/tubing strings.

Q:What material grades and steel types are available for your couplings?

Standard API grades: J55, K55, N80, L80, P110 High-pressure options: V140, V155 Corrosion-resistant alloys (CRA): L80-13Cr, Super 13Cr, Inconel 718 for sour service and corrosive environments

Q:Can you provide custom non-standard couplings (special sizes/threads)?

Yes. We specialize in precision-machined custom couplings, including non-standard sizes, special thread forms, and modified designs, to match your exact casing/tubing string requirements. All custom orders are processed with strict dimensional tolerance control and full quality inspection.

Q:How can I get an accurate quotation for couplings?

Please provide detailed technical requirements, including coupling size, material grade, thread type, quantity, and any special requirements (e.g., coating, testing). Our engineers will review your needs and provide a formal quotation within 1-2 working days.
