Cladding can be described as the welding of two materials with different qualities. A high-quality material can be clad on a cheaper base material in order to increase the erosion and corrosion resistance of a product: this is a good alternative for expensive duplex materials. Cladding (surfacing) is also applied to increase the mechanical qualities.
Delta Controls started with cladding of Stellite on valve parts for the petrochemical industry. This to increase the durability of the parts. We now have many years of experience in cladding for the petrochemical industry and also in the steel, paper, glass (fibre) producing and supplying industries.
The quality requirements on cladding are usually very high because it is mostly safety related. Delta Controls has the experience and knowledge to meet the highest standards of TÜV, ASME and Stoomwezen and the specifications of the customer. For example: degree of binding, percentage ferrite, hardness, chemical composition, cracking.
Delta Controls applies cladding mainly on:
- Valve parts
- Heat exchanger parts
- Nozzles for (petro)chemical barrels
- Bearing bushes for all industries
- Axle journals
- Wearing plates for concrete and sand industries.
New parts and repair
Cladding is applied on new parts as well as to repair old parts. Worn out parts can be used for a second lifetime by applying the right cladding materials. Repairing old parts instead of buying new parts, is both economically and qualitatively a very interesting option.
