Product Q&A
Q:What industry standards do your pup joints comply with?
A:
Our pup joints are fully manufactured in accordance with Spec 5CT (the international standard for casing and tubing products). We also operate under an Spec Q1 certified quality management system, ensuring consistent quality for oilfield applications.
Q:What types of connections do you support for pup joints?
A:
We support both standard threads and authorized premium connections. All premium threads are produced with full authorization, ensuring 100% compatibility with premium casing strings.
Q:What material grades and steel types are available for your pup joints?
A:
We offer a wide range of grades to meet diverse well conditions:
Standard grades (J55, K55, N80, L80, P110)
High-grade options (V140, V155) for high-pressure wells
Corrosion-resistant alloys (L80-13Cr, Super 13Cr, Inconel 718) for sour service and corrosive environments.
Q:Can you provide custom non-standard lengths for pup joints?
A:
Yes. We specialize in precision-machined custom lengths, including non-standard sizes, to match your exact casing/tubing string requirements. All custom orders are processed with strict dimensional tolerance control.
Q:Are your pup joints suitable for HPHT or sour service wells?
A:
Yes. For HPHT (High Pressure High Temperature) and sour service wells, we use CRA (Corrosion Resistant Alloy) materials like 13Cr and Inconel 718, combined with high-pressure rated premium connections, to ensure reliable performance in extreme conditions.
