| Specifications︰ | A clad metal plate is manufactured by laminating two metal plates or more and joining the laminated metal plates to each other. This clad metal plate is excellent in corrosion resistance, wear resistance and heat resistance, and has a high strength. Therefore, the clad metal plate is widely used as an inexpensive material.
As the methods for manufacturing clad metal plate, an explosion bonding process, a surfacing process and a rolling process are common. The rolling process, which can manufacture the clad metal plate of large area with high efficiency and at low cost, is most generally used.
Clad steel plate is produced to exact customer specifications. It is used to manufacture vessels or structures used in heavy industry projects where corrosion resistance qualities are essential. The main end users of clad steel plate include petrochemical companies, the shipbuilding industry, electric utilities,pulp and paper companies, and other users of industrial equipment like food, pharma etc. The petrochemical industry, specifically the hydrocarbon processing industry which includes petroleum refining and petrochemical and chemical processing, consistently has been the largest market for clad steel plate.
Rolling Process
--------------------------------------------------------------------------------
A method of manufacturing clad metal plate products by assembling in a stacked array a bottom base plate, a first cladding plate, a second cladding plate and a top base plate, with a separator compound layer between the first and second cladding plates. The peripheral dimensions of the cladding plates being less than the peripheral dimensions of the base plates. A metal rail is welded between the base plates and circumferentially of the cladding plates to form an assembly having a closed environment encompassing the cladding plates. Substantially all water and oxygen are removed from the closed environment. The assembly is then heated to an initial temperature of at least about 1850° F. and, while heated, is rolled or hydraulically pressed to cause the first cladding plate to bond to the bottom base plate and the second cladding plate to bond to the top base plate. Separating the assembly at the separator compound layer provides a first and a second clad plate. In the preferred application of the method, a cladding activator is electrolessly deposited onto the surface of each of the cladding plates that contact a base plate to incorporate liquid interface diffusion bonding of the cladding plates to the base plates.
Explosion Process
--------------------------------------------------------------------------------
The explosion bonding process, also known as "cladding by the explosion welding process", is a technically based industrial welding process. The process uses an explosive detonation as the energy source to produce a metallurgical bond between metal components. It can be used to join virtually any metals combination, both those that are metallurgically compatible and those that are known as non-weldable by conventional processes. Furthermore, this process can clad one or more layers onto one or both faces of a base metal, with the potential for each to be a different metal type or alloy.
Due to its use of explosive energy, the process occurs extremely fast; unlike conventional welding processes, parameters cannot be fine-tuned during the bonding operation. The bonded product quality is assured through selection of proper process parameters, which can be well controlled. These include material surface preparation, plate separation distance prior to bonding, and explosive load, velocity, and detonation energy. Selection of parameters is based upon the mechanical properties, mass, and acoustic velocity of each component metal being bonded. Optimum bonding parameters, which result in consistent product quality, have been established for most metals combinations. Parameters for other systems can be determined by calculation using established formulas.
Clad steel plate offers a low cost and highly effective solution in industrial sectors such as construction, shipbuilding and the manufacture of certain types of industrial tanks including pressure vessels.
Clad product manufactured in compliance to ASME SA 263, SA 264, SA 265 & B 432 under TPO LRIS / BVIS / TUV / ABS / Equivalent.
We can offer Dished Ends & Rolled Shell constructed form Explosion Bonded plates in the thickness range of 10+3 to 120+3 mainly SA 516 Gr. 40/65/60 + SS 316 L / 304 L.
All the clad metal materials would be used in the fields of petro chemical industry, salt industry, chlorin-alkali, food machinery, aviation and aerospace industry, medical machinery, light industry, heavy industry, cookware industry, ship building industry, electric industry， cryogenic industry and so on.
The interface strength between the dissimilar materials explosively welded on is strong enough to keep away from separateness, which it may be endure some external stress such as heat, bending, vibration or hard impact, in the late process.
According to the customer’s request, we, Runbang, absolutely comply with the manufacturing specification.
Such clad metal plates would be used in chemical vessels, reactors, heat exchangers, condensers, storage tanks etc.
For base materials mainly structural steels, pressure vessel steels and fine grain structural steels are used; they have proper weldability and workability.
For clad materials we offer ferritic and austentic stainless steels, nickel and nickel-based alloys, copper and copper-nickel-alloys as well as titanium, which are characterized by their corrosion resistance properties.
For detaillied information on steel grades please look into the brochure attached below.
The surface of the base material is normally "as rolled" or shot blasted.
The surface of the clad material is normally ground with a grain size of 80. Other grain sizes are available on request.
