This API 5CT seamless casing pipe from Oasis Oil Tools Co., Ltd is available in a 6 5/8 inch diameter, with wall thicknesses ranging from 5.12 mm to 16.13 mm and lengths in R1 (4.86 - 7.62 m), R2 (7.62 - 10.36 m), or R3 (10.36 - 14.63 m) ranges. The material options include carbon steel grades such as J55, K55, L80, N80, and P110, as well as stainless steel 304/304L and 316/316L for corrosion-resistant applications. Connection types for casing include STC, LTC, BTC, and EUE, while tubing connections are available in EUE and NUE.
The pipes undergo standard surface treatments such as blank oil painting with colour-coded ends (e.g., green, red, white, or brown) for easy identification. Packaging typically includes bundling with steel strips and plastic thread caps to protect the ends during transit. Third-party inspection by agencies like BV or SGS is available upon request, ensuring compliance with API 5CT standards for dimensional tolerance, material properties, and pressure integrity.
These casing pipes are primarily used in oil and gas well construction to prevent cave-ins, isolate formations, and facilitate fluid extraction. Buyers in the upstream oil and gas sector source them for both onshore and offshore projects, where the casing’s strength and corrosion resistance are critical. The supplier’s offerings also extend to custom sizes and connections, such as threaded flange ends, to meet specific project requirements.

Before placing an order, verify the material grade and connection type to ensure compatibility with your well design and downhole conditions. Confirm the pipe’s pressure rating and yield strength, as these are critical for well integrity. Request mill test certificates and, if applicable, third-party inspection reports to validate the pipe’s compliance with API 5CT standards.
Logistics arrangements should include clarification of Incoterms (e.g., FOB Xinxiang or CIF destination port), lead time, and packaging specifications. For international shipments, ensure the supplier provides all necessary export documentation, including a commercial invoice, packing list, and certificate of origin. Buyers should also confirm whether the supplier can arrange marine insurance for the cargo.
Quality checks should focus on dimensional accuracy, thread integrity, and surface condition. Inspect the pipes for defects such as cracks, pitting, or improper threading, which could compromise performance. For stainless steel grades, verify the passivation treatment to ensure corrosion resistance. If possible, arrange a pre-shipment inspection by a recognised agency to confirm the pipes meet your project’s technical and regulatory requirements.
