The two-post hydro-mechanical cleaning unit is designed for cleaning the internal cavities of the coils of technological tubular furnaces, pipelines for the oil, oil refining and petrochemical industries;
The hydro-mechanical cleaning unit consists of a high-performance centrifugal pump, diesel drive, gearbox, clutch, fuel tanks, buffer tank, strapping, automatic control system
diesel drive, valve system and control panel. The unit also includes all the necessary sensors for monitoring the pressure and pump performance, which allows you to control the cleaning process and objectively evaluate its results. The movement of the scraper in the coil cavity is tracked on the monitor using special software.
Start-up and receiving devices (hereinafter referred to as PPU) are special devices that allow you to connect a hydro-mechanical cleaning unit to the pipeline section to be cleaned, to create a single closed cleaning circuit. Through the starting and receiving devices, the cleaning projectiles are launched and further changed into the pipeline cavity; When cleaning the furnace coil or pipeline, starting and receiving devices of various sizes can be used, as a rule, they are selected from the closest in size
row (up). In some cases, PUF of different sizes can be installed at the entrance and exit to the cleaned area. The standard sizes of the software vary depending on the diameter of the patency of the foam: 100mm (4 inches), 150mm (6 inches), 200mm (8 inches), 250mm (10 inches), 300mm (12 inches). The size of the PUF depends on the limitation of the largest size of the cleaning scraper used; The standard PUF consists of a charger, shut-off valves, a bleed valve and a locking grid.
For cleaning the inner surface of furnace coils and pipelines by the hydro-mechanical method, temporary docking bends with counter flanges of the STD 300 Lbs ANSI/ ASME B 16.5 standard are mounted at access points by the Customer. The temporary branch is mounted so that the flange axis is positioned horizontally, at a height of about 0.8 meters from the zero mark or the level of the technological site. The minimum dimensions of the site where the Contractor's starting and receiving devices will be installed must be at least 2.5x2.0 m, and are agreed with the technical specialists of Krok LLC
The hydro-mechanical cleaning unit is also equipped with:
Our company is always ready to promptly send a technical specialist to inspect the cleaning facility, select the most acceptable options for connecting equipment, and advise Customer representatives on issues of hydro-mechanical cleaning at the site.
