These API 5CT K55 casing pipes are manufactured for oil and gas drilling operations, available in seamless and electric resistance welded (ERW) variants. The pipes comply with API 5CT and API 5B standards, ensuring structural integrity for borehole support and collapse resistance in high-pressure environments. Outer diameters range from 4 1/2" to 20" (114.3 mm to 508 mm), with thread types including LTC, STC and BTC for compatibility with standard drilling equipment.
K55 grade steel is selected for its balanced strength and ductility, with a minimum yield strength of 375 MPa (54,400 psi) and tensile strength of 552 MPa (80,000 psi), typical for shallow to medium-depth wells. The pipes undergo hydrostatic testing at pressures up to 70% of specified minimum yield strength and are inspected for dimensional accuracy, wall thickness and thread integrity. Standard lengths are 8 to 13 m, with custom lengths available upon request.
These casing pipes are primarily used by oil drilling contractors and gas extraction companies to line boreholes, prevent cave-ins and isolate different geological formations. They are supplied in bulk for wholesale distribution, with applications in onshore and offshore drilling projects. Buyers typically specify outer diameter, wall thickness, thread type and length to match their drilling rig requirements.

Before ordering, verify the grade (K55) meets your project’s depth and pressure requirements, and confirm the thread type (LTC, STC or BTC) matches your drilling equipment. Request mill test reports and hydrostatic test certificates to validate compliance with API 5CT standards, as these documents are essential for quality assurance and regulatory compliance.
Discuss logistics details such as Incoterms (FOB or CIF are standard for Chinese suppliers), lead times for production and shipping, and payment terms (L/C or T/T are common). The port of loading is likely Cangzhou or a nearby major port, so factor in shipping routes, transit times and customs clearance procedures. For bulk orders, confirm packaging options to prevent damage during transit, especially for threaded ends.
Quality checks should include dimensional inspection for outer diameter, wall thickness and length, as well as visual and non-destructive testing for defects. Request a pre-shipment inspection by a third-party agency like SGS or Bureau Veritas to ensure the pipes meet API 5CT specifications. Verify that all documentation, including packing lists, certificates of origin and compliance, is complete and accurate for smooth customs clearance and project approval.
