This well flushing truck combines two duties in one unit: a triplex plunger pump rated up to 35, 40 or 70 MPa at 50, 60, 80 or 100 m3/h for cold high-pressure flushing, and a fired heater that delivers hot wash at 20 MPa and 160, at no less than 22.5 m3/h and still 4.9 m3/h at peak temperature. Because it circulates crude or water through a closed loop, it melts paraffin and jets scale in a single mobilization rather than sending a flushing truck and a boiler truck separately. The 70 MPa cold-flushing head clears hardened scale; the 160 loop melts wax a cold jet cannot, which is why the integrated truck is the standard for long-producing wells where deposition and blockage arrive together.
The triplex plunger pump, driven directly off the truck engine, reaches 35, 40 or 70 MPa at 50 to 100 m3/h. That cold jet breaks hardened scale and sand fill that a heating-only circuit would not dislodge, which is the high-pressure half of the integrated job.
The fired heater delivers hot wash at 20 MPa and 160, circulating at least 22.5 m3/h and still 4.9 m3/h at peak temperature. That thermal half is what melts tubing-wall wax into a flowable state instead of scraping it.
Cold flushing and hot wax removal share one chassis, one pump and one loop, so a deposition-and-blockage well is cleaned in the shift one truck is on site. The 70 MPa head and the 160 loop are two modes of one vehicle, not two vehicles.
The loop handles produced crude and water, not only fresh water, which lets the truck circulate well effluent for wax melting without a separate supply. The burner runs on diesel regardless of which medium is circulated.
The triplex plunger pump takes power from the truck engine through a 24 VDC control circuit, so pressure and flow are adjusted from the cab without a separate power pack. The 35/40/70 MPa ladder is set by pump spec, not by auxiliary power.
Both halves are regulated: cold flush pressure against the 70 MPa ceiling and hot wash against 160 and 20 MPa. The closed loop modulates burner and pump so the run does not overshoot either rating, which matters when wax and scale must be cleared without tubing damage.

Buyers evaluating the flushing and paraffin removal truck usually ask about pump rating and wax-removal scope.
It is a multi-functional oilfield well maintenance unit integrating high-temperature paraffin removal and high-pressure well flushing. It removes downhole paraffin deposition, sediment and scale blockages, dredges wellbore flow channels, restores formation permeability and oil well productivity, and ensures stable and efficient operation of production and water injection wells.
It serves conventional production wells, water injection wells and recompleted old wells across the 0-6000 m depth window, with the 70 MPa cold-flushing head for scale-blocked bores and the 160 °C hot-wash loop for tubing-wall wax. It is the standard choice for long-producing wells where wax deposition, settled silt and declined output arrive together, and for batch maintenance of cluster-well groups.
Yes. The truck runs a closed-loop heated fluid circuit combined with high-pressure jet flushing: the hot loop softens solid paraffin and the jet washes silt and scale from the tubing wall. The firing rate and flushing pressure are set against the well history rather than run at a fixed value, which is what prevents the repeat blockage that comes from one-size-fits-all cleaning.
Yes. The truck is built for year-round flushing and paraffin service, with the triplex pump and fired heater package protected for cold and dusty conditions; the 70 MPa cold-flush head and the 160 °C hot-wash loop are the figures that do the work in winter. Confirm the site climate and the winterising requirement in the inquiry so the provisions are quoted explicitly.
Yes. The integrated truck is specified per program: the cold-flushing pressure grade (35, 40 or 70 MPa) and displacement (50, 60, 80 or 100 m3/h) are chosen against the well's scale severity, while the hot-wash side is fixed at 20 MPa and 160 with circulation of no less than 22.5 m3/h (4.9 m3/h at peak temperature). We set whether the loop circulates produced crude or water, and the triplex pump and diesel burner are matched to that choice; the selected configuration is recorded in the factory hydrotest and burner test report.
Commercial terms are confirmed in the quotation for the exact configuration, quantity and destination.
Built to API oilfield equipment specifications at the Jingzhou plant under ISO 9001:2015 quality management; the triplex pump is hydro-tested to its 35/40/70 MPa rating and the fired heater to its 160 °C outlet and 20 MPa hot-wash limit before dispatch.

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.
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.
