PLUNGER

METAL SPRAY PLUNGER

Complete line of spray metal plungers with the hardest most corrosion resistant metals available. Each plunger and/or plunger component must meet corresponding metallurgical and precision standards, as well as the dimensional standards of API 11AX latest edition.

Specification: 1.1” (φ28mm) –6.3” (φ160mm)

Regular Plunger Length: 1ft-6ft (Can be customized)

The metal spray plunger Using oxygen, acetylene spray welding technology, spray the nickel base alloy powder to pass through the surface of the coarsening and activation of matrix, and then heated to the temperature range of solid liquid phase line to melt and tile alloy materials and get the modified surface welding layer, thus transforming the anti-wear & corrosion performance of the workpiece. The spray metal thickness can be subject to the working condition of the actual requirements, the minimum thickness 0.203mm, welding layer and base metal metallurgy brazing, the bonding strength can be up to 200 ~ 300 Mpa. The Nickel base alloy powder and base has good bonding strength, better shock resistance, higher hardness, wear & corrosion resistance, anti-oxidation can be up to 650 ℃, which can make good friction pair with pump barrel.

NITRIDE PLUNGER

Nitriding is a heat-treating process that diffuses nitrogen into the surface of a metal to create a case-hardened surface. Nitriding Plunger applies gas nitriding surface hardening process, where nitrogen is added to the surface of plunger using dissociated ammonia as the source. The nitriding plunger increases wear resistance, surface hardness, fatigue limit and corrosion resistance.

METAL SPRAY LONG PLUNGER

The long plunger sand pump with short pump barrel, Long plunger, sinking sand and lateral inlet structure is a more widely used sand control pump, through up and down strokes of plunger, the liquid will flow to the ground through duplex connector and double-stage standing valve, at the same time, part of sand that doesn’t carrying up in the tubing string will sink into the grit tail pipe through the annulus between pump barrel and grit tube as well as duplex connector.

Type:

1. Long plunger connected by a 1.2m or 1.5m long short plunger

2. Integral long plunger with metal spray, straightening and whole grinding

Features：

1. The outer surface is adopted metal spray technology, which can ensure that the plunger has the characteristics of corrosion resistance, wear resistance and size stability for a long time.

2.The long plunger with high precision size, good straightness and concentricity, small flow resistance coefficient and smooth surface, is not easy to scale and stuck pump.

EQUAL DIAMETER PLUNGER

Structure:

Equal diameter plunger is composed of upper and lower equal diameter connector, plunger and traveling valve cage.

Features:

1. Sand control, sand control grinding, effectively extend the production cycle of oil Wells

2. Low price, high efficiency.
