40 MPa water jet
The triplex pump delivers a 40 MPa water jet at up to 30 m3/h, sized to break sediment and scale without the cost and complexity of a heating loop. It is the cold-flushing half of the integrated truck, offered as a standalone unit.

This is the single-purpose water flushing truck, sized at 40 MPa maximum pressure and 30 m3/h maximum displacement, with a booster pump fed at 12 to 16 MPa inlet pressure. It circulates water only, with no heater and no wax-melting loop on board, which keeps the package simpler and cheaper than an integrated flushing-and-paraffin unit for wells that need jet cleaning rather than thermal melting. A built-in decompressor steps inlet pressure down to no more than 0.8 MPa outlet at up to 35 m3/h, so the same truck can both high-pressure flush and low-pressure circulate sand or cuttings. That 40 MPa cold-water head is what clears sediment, scale and residual plugging on standardized post-workover well finishing.
The triplex pump delivers a 40 MPa water jet at up to 30 m3/h, sized to break sediment and scale without the cost and complexity of a heating loop. It is the cold-flushing half of the integrated truck, offered as a standalone unit.
Maximum displacement of 30 m3/h sets how fast fill is lifted out; the decompressor then opens the circuit to up to 35 m3/h low-pressure circulation. The two flow regimes cover both cutting scale and carrying sand to surface.
A booster pump feeds the circuit at 12 to 16 MPa inlet pressure, which stabilizes suction on draws from a nearby line or tank and avoids cavitation at the 40 MPa head. That inlet margin is what keeps the jet steady on long runs.
The on-board decompressor takes inlet pressure up to 40 MPa and steps it to no more than 0.8 MPa outlet at up to 35 m3/h, letting the truck switch from high-pressure jetting to gentle circulation. One chassis covers both regimes instead of needing a second unit.
The medium is water, so there is no burner, no crude-handling loop and no wax-melting function. For wells that need scale and cuttings removed but not thermal cleaning, that omission is the cost saving versus the integrated flushing-and-paraffin truck.
With no thermal module to service, the truck is aimed at repeatable post-drilling and post-workover wellbore finishing: pressure, flow and decompressor settings are documented per job, which is what batch well-maintenance programs need.

Questions about the well flushing truck cover flushing pressure, flow rate and tank capacity.
The Well Flushing Truck is a professional single-function well service equipment, focusing purely on high-pressure well flushing, sand washing and scale dredging with more stable pressure output and higher cleaning efficiency. The integrated model adds wax melting and heating functions. This professional flushing truck is more suitable for standardized, large-batch daily well cleaning operations with lower failure rate and higher cost performance.
It serves 0-6000 m conventional production wells, water injection wells, newly completed wells and recompleted old wells. Its 40 MPa / 30 m3/h water jet is aimed at post-workover well finishing, regular wellbore dredging and pressure testing, and the built-in decompressor adds low-pressure circulation (up to 35 m3/h at no more than 0.8 MPa outlet) for batch well-maintenance programmes.
Yes. The triplex plunger pump holds the 40 MPa / 30 m3/h rating steadily: the booster feeds the circuit at 12 to 16 MPa inlet pressure to avoid cavitation, and the control loop trims pump output against back-pressure, keeping flushing pressure and rate near set point so the jet does not surge or hammer the wellbore while sediment and scale are lifted to surface.
Yes. The truck is specified for continuous flushing service across climates, with the 40 MPa / 30 m³/h pump and 12–16 MPa booster package protected for cold and dusty sites; the decompressor also allows low-pressure circulation at up to 35 m³/h when flushing duty is not required. Confirm the winterising scope with the inquiry so it is included in the quotation.
Yes. The configuration is settled against the flushing programme before the order: working pressure grade (40 MPa rated), displacement range (30 m3/h), booster inlet arrangement (12 to 16 MPa), decompressor settings, explosion-proof specification and monitoring package are matched to well depth, blockage condition and the operator's water-supply standard, then written into the quotation and the factory hydrotest report.
Commercial terms are confirmed in the quotation for the exact configuration, quantity and destination.
Built to API oilfield equipment safety standards at the Jingzhou plant under ISO 9001:2015 quality management; the triplex pump is hydro-tested to its 40 MPa head and 30 m3/h displacement, and the 12 to 16 MPa booster inlet and decompressor step (up to 40 MPa inlet to no more than 0.8 MPa outlet at up to 35 m3/h) are set and recorded before dispatch. Certificate scope and applicable standards are listed in the quotation.
Operation and maintenance manuals, chassis documentation and factory test reports are supplied; the hydraulic and electrical schematics are included for the client's service department.

A boiler truck earns its keep by heat, not by pressure: this unit delivers working water at up to 280 through a fired tube package rated at 6 or 9.8 MPa, at a hot-water or steam output of 1.26, 1.8 or 3.0 t/h.

Three pulling ratings define this coiled tubing line: ZLG155/38 holds 155 kN continuous tension, ZLG225/45 holds 225 kN and ZLG290/50 holds 290 kN, with laying depths of 3600, 4200 and 5900 m on 1.5-inch tubing.

The swabbing unit is rated by a drum-dependent lifting envelope: up to 120 kN at minimum drum diameter, down to 80 kN as the drum fills, with a maximum working depth of 3350 m.
