There is no universal method: the choice depends on the equipment design, material, access to surfaces, and the composition and amount of deposits. We select the method after an inspection and agree it with the customer.
How we choose the method
- equipment design and access to contaminated surfaces;
- material: carbon and stainless steel, copper, brass, aluminium;
- composition of deposits: scale, corrosion products, organics, petroleum products, soot, coke;
- whether the equipment can be dismantled and how long the shutdown can last;
- requirements for the result and for subsequent coating.
Cleaning methods
- Chemical flushing — deposits are dissolved by chemicals circulated through the internal cavities of the equipment, followed by neutralisation and passivation of the metal; used where tools cannot reach.
- Hydrodynamic cleaning — deposits are broken up by a high-pressure water jet using high-pressure units, sewer-cleaning hoses and special nozzles; for tubes, channels and vessels accessible to a nozzle.
- Mechanical cleaning — removal of hard and fully blocking deposits with manual and power tools; as a rule, requires dismantling or opening the equipment.
- Dry ice blasting (cryoblasting) — gentle cleaning of accessible surfaces with solid carbon dioxide pellets, without chemicals, water or abrasives.
- Laser cleaning — non-contact removal of rust, mill scale, carbon deposits and coatings from accessible metal surfaces.
The suitability of a method for specific equipment is determined after inspection and agreed with the customer; methods are often combined. To get a quote, use the form below or write to zakaz@bxk.ru.
