We have completed a large-scale API 5CT oilfield casing pipe supply project for GLOBAL OILFIELD EQUIPMENT SUPPLY LIMITED, supporting oil and gas field development in Nigeria. The total supply capacity reaches 2220.67 tons, covering three mainstream casing grades: N80Q-BC, L80-1-BC and K55-BC. All oil casings adopt unified standard dimensions: 339.72mm outer diameter and 12.19mm wall thickness, which are widely used in onshore oil well drilling and completion projects. As essential downhole tubular goods,BC grade casing pipes feature outstanding wellbore support, pressure resistance and formation protection performance. With stable mechanical properties, excellent collapse resistance and good adaptability to harsh environments, these oilfield casings perfectly fit Nigeria’s complex geological and downhole conditions. This large-volume export project strengthens our market competitiveness as a professional West Africa oilfield casing supplier and builds long-term cooperative ties with local oilfield equipment enterprises.
2220.67T API 5CT Casing Pipe Supply | N80Q-BC/L80-1-BC/K55-BC for Nigeria Oilfield
Project Challenge
This multi-grade and large-volume casing project posed core challenges in technical precision, mass production and cross-border export: 1.Multi-Grade Precision Control: Three casing grades (N80Q-BC, L80-1-BC, K55-BC) share identical dimensions but differ in technical standards, requiring strict classified production to avoid mixing errors. 2.Strict Oilfield Standard Requirements: All API 5CT casing pipes must pass professional hydrostatic, collapse resistance and dimensional tests to meet Nigeria oilfield safety operation standards. 3.Mass Production & Delivery Pressure: The 2220.67-ton bulk order required stable continuous production and flexible batch shipment to match the client’s construction schedule. 4.Complicated Nigeria Customs Clearance: Oilfield tubular goods face strict import inspection rules, requiring complete and standardized certification documents for smooth customs release.
