Import Esp Cable Protector Cross Coupling — Buy in wholesale FOB from Supplier in China

The ESP cable protector cross coupling is a precision-cast downhole component designed to shield electrical submersible pump cables from abrasion and mechanical stress during deployment in oil and gas wells. It is manufactured using high-grade alloy steel with a tensile strength of 758 MPa, as confirmed by the supplier's internal testing, and features a threaded body with standard API 6A thread profiles for secure connection to tubing and casing. The internal bore diameter is 38.1 mm, and the outer diameter measures 76.2 mm, matching common ESP cable diameters used in high-temperature, high-pressure environments.

The casting process uses sand mold technology with controlled cooling to minimize porosity and ensure structural integrity under downhole pressures up to 15,000 psi. The surface finish is machined to a Ra 3.2 µm tolerance, and the material composition typically includes 0.35% carbon, 1.2% manganese, and trace chromium for wear resistance. These characteristics align with standard industry requirements for downhole protection tools, where material consistency and dimensional accuracy are critical to prevent cable shearing and premature failure.

This component is primarily purchased by oilfield service companies and well completion contractors operating in mature fields with long production strings, particularly in the Middle East, North Africa, and Southeast Asia. Buyers typically order in batches of 50 to 200 units, packaged in steel crates with foam inserts to prevent transit damage. Trade terms are commonly FOB Qingdao or CIF Rotterdam, with lead times averaging 4 to 6 weeks after deposit. Certification documentation for material traceability is available upon request.

Puyang Zhongshi Group Co., Ltd is a manufacturer based in Mazhaungqiao Industrial Zone, Puyang City, Henan Province, China, with operations focused on downhole oilfield tools since 1997. The company produces cementing heads, stage collars, float equipment, and downhole cable protectors using casting and machining processes. Their profile confirms production capability and direct manufacturing, but does not state annual output, workforce size beyond a general reference to nearly 400 workers, or client names.

The supplier responds to inquiries via email and WhatsApp, indicating active commercial engagement, but has no verified third-party audit or certification listed in the source data. Their product range is specialized, with no indication of broad distribution or retail presence. They do not claim ISO certification, API monogram licensing, or export volume data. All claims are limited to their own production descriptions and contact details.
