Api 5ct Oil Casing And Tubing Seamless Oil Pipe
Api 5ct Oil Casing And Tubing Seamless Oil Pipe from Tianjin Dalipu Oil Country Tubular Goods Ltd. is manufactured in grades H-40, J55, K-55, N-80, C-75, L-80, C-90, T-95 and Q-125, covering both ERW and seamless processes. Casing outer diameters range from 4 1/2" to 20" (114.3mm to 508mm) while tubing spans 2 3/8" to 4 1/2" (60.3mm to 114.3mm), with wall thickness options from 0.205" to 0.635". Lengths are supplied in R1 (4.88m to 7.62m), R2 (7.62m to 10.36m) or R3 (10.36m or longer) as per API 5CT standards for wellbore integrity.
The material composition includes carbon and alloy steel, with heat treatment applied via normalization or quenching and tempering to meet mechanical and technical properties. Connection types for casing include LTC, STC and BTC, while tubing uses NUE or EUE, with beveled or square-cut ends and protective caps. Surface treatment involves corrosion-proof water-based paint, and each pipe undergoes rigorous testing, including chemical analysis, tensile and yield strength checks, flattening, flaring, bending, hardness and impact tests, as well as hydrostatic and non-destructive inspections using ultrasonic and eddy current flaw detectors.
These pipes are primarily used in petroleum and natural gas extraction, where they must withstand extreme pressure and corrosive environments, particularly in sour service conditions. Buyers typically include oilfield contractors, drilling operators and energy sector suppliers sourcing bulk lots for global projects. Tianjin Dalipu Oil Country Tubular Goods Ltd. bundles the pipes in hexagonal bundles of up to 2,000kg, wrapped in waterproof paper, PVC sleeves and sackcloth, with plastic plugs at both ends and steel strip reinforcement for safe transport.

Sourcing Api 5ct Oil Casing And Tubing Seamless Oil Pipe from Tianjin Dalipu Oil Country Tubular Goods Ltd. - China Import Guide
Before ordering Api 5ct Oil Casing And Tubing Seamless Oil Pipe from Tianjin Dalipu Oil Country Tubular Goods Ltd., verify the exact steel grade and heat treatment process to match your wellbore conditions. Confirm that the connection type (LTC, STC, BTC for casing or NUE, EUE for tubing) is compatible with your existing equipment and operational requirements. Request documentation for the mechanical properties, including tensile strength, yield strength and elongation, as these are critical for ensuring the pipe’s performance under pressure.
Discuss logistics details such as lead times, which may vary based on the grade, size and quantity ordered. Clarify Incoterms, with FOB Tianjin or CIF to your nearest port being common options for bulk shipments. Payment terms typically include a percentage deposit with the balance due upon inspection or before shipment, so ensure these align with your procurement policies. Packaging should be confirmed as hexagonal bundles of up to 2,000kg, with waterproof wrapping and protective caps to prevent damage during transit.
Quality checks should include a review of the hydrostatic test results, which confirm the pipe’s ability to withstand internal pressure without leaking. Request certificates for non-destructive testing, such as ultrasonic and eddy current inspections, to verify the absence of defects. Inspect the surface treatment and packaging upon arrival to ensure the pipes are free from corrosion and physical damage. For sour service environments, confirm that the selected grade (e.g., Q-125) meets the required sulfide stress cracking resistance standards.
