Crystal Industrial from India: Supporting a wide range of industries with advanced steel rolling method.
Two of the growing needs globally today are for removal of natural gas to satisfy clean energy demands, and for desalination plants to address the worldwide deficiency of water resources. Using our advanced steel rolling procedure, we are producing clad steel plates and pipings to help satisfy these necessities.
Highlights
Crystal Industrial’s Clad products from India are composite materials merging diverse amalgams with steel, and have a number of special features not found in standard steel. These products routinely feature the blend of carbon steel or low-alloy steel to ensure toughness with stainless steel or high-amalgam steel to incorporate corrosion resistance.
Subjected to strict quality controls and accepted by customers for many years, our clad steel items have a sound reputation for safety supported by an increased level of corrosion resistance and usefulness accomplished through the perfect mix of materials.
Economy
The thickness of the expensive corrosion resistant metal is made as thin as it can be with the desired sturdiness being given by the backing steel. The cladding proportion and the size of the clad plates can be fabricated to satisfy customer’s requirement. In other words, flexibility of materials and made-to-arrange sizes of the cladding metal and backing steel raises the possibility of diminishing the material cost.
Excellent heat conductivity
Normally, clad plates have preferred thermal conductivity over the solid plates and this similarly broadens the application range where higher thermal conductivity is required.
Higher design stress
Extremely good mechanical features of clad plates are obtained by selection of chemical compositions and heat treating states of the backing steel. Thus, it is useful to raise the design stress and decrease the plate thickness.
High security component
Right when stress corrosion cracks on solid wall vessels of stainless steel or distinctive metals, such breaks would transmit through the wall. Regardless, the use of clad plates will increase the security component as spread of such breaks is turned away by the bond zone and backing steel and Ni-plating stops the corrosion of backing steel.
1. Preparation
The attachment surface of both cladding metal and backing steel are ground and totally cleaned. The holding surface of the cladding metal is nickel-plated to ensure metallurgical bond. The back of the cladding metal is secured with an infusible isolating compound.
2. Assembly
Two sets of plates, each with the backing steel outside and cladding metal internally are coordinated together to make a composite assembly and after that fitted along the edges by welding. The welding is done to protect the corrosion resistant amalgam from possible impurity by revelation to surroundings while heating before rolling.
3. Rolling, Heat-Treating and Cutting
The intricate assembly is heated to the suitable temperature in a warm heater and rolled to the given sizes in order to connect the cladding and backing materials metallurgically. Consequent to rolling, the assembly is dealt with thermally as required considering the mechanical features of the backing steel and corrosion resilience of the cladding metal. The assembly is then separated into two clad plates to be cut as per the given measurements.
4. Surface Finishing and Packaging
Both cladding and backing plates are surface-cleaned to preclude destructive deformities. In particular, the corrosion-tolerant surface of the cladding metal is ground by harsh belt and pickled. The cleaned clad plates are dispatched with the surfaces properly protected against damage while transportation.
5. Testing and Inspections
To assure and endorse the standard of the clad plates, ultrasonic examination and mechanical testing are carried out with the assistance of a computer system.
