Thread Cold Drawn Pipe for Electric Submersible Pump Motors

THREAD cold drawn pipe for Electric Submersible Pump Motors (commonly referred to as threaded cold-drawn tube) is a critical precision component specifically engineered for harsh downhole oil well environments. Unlike conventional pipes that have built-in threads, this specialized tube is manufactured --through cold-drawing technology and primarily serves motor housing sections requiring threaded connections (such as API threads).

The core function is to provide a robust, sealed, and efficient protective casing for the core --motor --of an electric submersible pump (ESP). Operating at depths of thousands of meters underground, the motor endures extreme challenges including high temperatures, high pressure, and corrosive fluids such as oil, gas, water, and hydrogen sulfide. This casing must effectively isolate well fluid from entering the motor, preventing short circuits and burnout, while also demonstrating superior mechanical properties to withstand extreme external pressures.

THREAD cold drawn pipe for Electric Submersible Pump Motors is a high-performance tubular product specifically designed for the demanding environments of submersible pump systems. Manufactured from superior steel grades such as 16Mn, E355, 25Mn, 20#, 45#, stainless steel 316L, 304, and specialty alloys including 13Cr and Super 13Cr, this pipe ensures excellent mechanical properties and corrosion resistance.

The cold drawing process guarantees strict dimensional accuracy, uniform diameter, and outstanding straightness, which are critical for the reliable operation of ESP motors. Available in common types such as 338, 400, 513, 538, 562, 675, 862, and 950, with lengths ranging from 3 to 12 meters, the product can also be customized in terms of cutting, threading, and end finishing-such as threaded ends or protective caps-to meet specific customer requirements.
