Import Api 7-1 Casing Cup Tester For Pressure Testing — Buy in wholesale FOB from Supplier in China

The API 7-1 Casing Cup Tester is a pressure verification device used to validate the structural integrity of casing cups during deep well drilling operations. It is built to API Specification 7-1, the standard governing rotary table equipment and related downhole tools. The tester applies controlled internal pressure to casing cup assemblies to detect leaks, deformation, or failure points before deployment in the wellbore. Dongying Lake Petroleum Technology Co., Ltd. manufactures this unit at its facility in Dongying, Shandong Province, a region with established oilfield equipment manufacturing infrastructure.

Construction typically involves alloy steel bodies with hardened sealing surfaces to withstand repeated pressurisation cycles. Standard working pressure ranges for casing cup testers fall between 35 MPa and 105 MPa, depending on casing grade and well depth requirements. The device incorporates precision pressure gauges or digital transducers with accuracy classes of 0.25 percent or 0.4 percent of full scale, calibrated against certified dead-weight testers. Seals are usually nitrile rubber or fluorocarbon elastomer, selected for compatibility with drilling fluid chemistries and temperature exposure up to 150 degrees Celsius in typical service conditions.

Operators purchase these testers for preventive maintenance programmes, pre-run equipment audits, and regulatory compliance verification. Buyers include drilling contractors, oilfield service companies, and equipment rental firms operating in onshore and offshore environments. Trade terms for this category of equipment are typically EXW or FOB Qingdao, with packaging in wooden crates for sea freight.
