Cold Cutting
Hydro Abrasive-Cold Cutting
Cutting steel in hazardous areas.
BDS Contracts (MH) Ltd offer effective and safer alternative to hot cutting methods by using high pressure water jets mixed with abrasive. By using abrasive water jet cutting, it means that if heat and spark free cutting is required in a potentially explosive atmosphere.
Advanced cold cutting has gained a wealth of experience on decommissioning, shutdowns, demolition and salvage projects over the past twenty five years. This along with our excellent safety record, state of art equipment and dedication to customer care, makes us leaders in our field.
Abrasive water jet cutting or hydro abrasive cutting is a proven cold cutting method with the following unique properties and distinct advantages:
- Totally cold cut for use in hazardous environments
- Drastically reduces the need for costly plant shutdown & preparation time for hot work
- No heat generation maintaining material properties/structure
- Capable of cutting virtually and material or thickness
- Jet cut creates its own start point so does not require an edge or need to overrun
- Cutting Head and manipulators are portable and versatile – ideal for restrictive areas
- Cut can be completed in a single pass but with a multi pass option if required
- Shock free cut can be used for controlled demolition
- Good quality angled cut leaves the surface already prepared for re-welding
- Remote operation eliminates operation exposure at cut face
- Non contact blade i.e. no snagging or need for support
- Environmentally friendly as uses no hazardous materials and creates no gases or dust
Case Study
The images above where taken during de-commisioning a refinery where the steel was 10mm thick with 100mm refractory lining, these had to be accurately cut as the plant was being re-assembled in India. Cold cutting as you can see achieved everything we promised the client and with its remote operation these 20 tonne sections where safely craned away on completion of cut with the operator at a safe distance.
