Chrome Plating Heavy Walled Oil Well Sucker Rods Tubing Type

Chrome Plating Heavy Walled Tubing Type Downhole Pumps

Heavy walled tubing type downhole pumps Description

Tubing type pumps' barrel is heavy walled. For some large production wells, larger bore of tubing pump can be worked if the on-off connector is installed. Tubing pump is the strongest pump. It has large flowing area for fluid and it is suitable for producing viscosity oil.

In the process of production, when traveling valve and standing valve appear problems,we can pull the traveling valve and standing valve out the well through the sucker rod string, plungerand the puller ,instead of pull the whole pump and tubing string out of the well, reduce the labor intensity of operation, reduce the operation cost.

Some pump technical parameters:

Material selection:

API Spec. 11AX was modified to add not only new sizes and types of pumps with new quality, inspection, and tolerance requirements, but also standardized, widely used pump-component materials. Various material descriptions, their API identification symbol, surface condition, base core hardness, base material, and base-material minimum yield strength for plated barrels, are shown in Table A of Spec. 11AX. Similar tables in Spec. 11AX (B through I) are incorporated for case-hardened barrels, nonhardened barrels, balls and seats, cages, pull tubes, valve rods, fittings, seating cups, spray-metal plungers, and plated plungers. These changes have incorporated the prior information in API RP 11AR^[2] and the NACE International MR 01-76^[3] for materials to be used in most production environments.
