Casting Products – Dynamic
CASTING PRODUCTS - DYNAMIC
We have two main foundries for casting products: one is static fine casting for heat resistant grid, basket, loading rail, etc.; another is dynamic casting for centrifugal casting tube and accessories.
Complete service from consulting, engineering, manfacturing to after-sales.
PRODUCTS DETAILS
Manufacturing for heat-resistant centrifugally cast tubes:
– Small diameter ethylene tubes (Ø 50-100 MM), large diameter reformer tubes (Ø 100-300 MM), tubes for continuous annealing / galvanizing lines, furnace rollers and radiant tubes.
– Elbows, return bends, Wye-pieces, Tee-pieces, Tetra fittings, bottom manifolds, reducing cones.
Radiant Coil Assemblies, Reformer/Catalyst Tubes, Radiant Harp Assemblies, Radiant Tubes and Furnace Rolls, Tube sheets, Catalyst Grids
– Reformer furnace applications including ammonia, hydrogen, methanol and DRI
– Cracking furnaces of ethylene and naphtha gas
– Convection Zones
– Steel Industry
Radiant Coils, Finned tubes, Studded tubes, Convections Zones, Drawn pipes (Seamless), Tube sheets, Accessories.
In cracking furnaces raw materials such as ethane, liquefied petroleum gas (LPG), naphtha, atmospheric gas oil (AGO) and hydrocracker residue are converted into ethylene and valuable by-products. Modern cracking furnaces have capacities of over 250,000 MTA of ethylene and fired duties of over 100 MW per furnace in short residence times. Operating temperatures even exceed 1000-1150° C. Thermal cracking processes need radiant coil systems – essentially consisting of high-alloy tube assemblies, fittings or bent tubes – all welded, gas-tight constructions.
Complete radiant coil systems, tube assemblies, fittings as spare parts are regularly changed in existing crackers and installed in new capacities. Global demand of ethylene is continuously growing.
For pre-assembling and final assembling we are trusting in experienced professionals. Utilising manual welding techniques of proven and repeatable quality, we are meeting with the most stringent of specification requirements. Qualified welding procedures are certified to ASME/EN/BS standards, covering all materials from cast alloy range and materials including stainless steels and carbon steels, Cr-Mo and Nickel-base alloys.
Manufacturing standards: HG/T 2601, ASTM A608, DIN 10295, JIS G5122, etc.
Tests: Chemical analysis by spectrometer for each casting, eddy current test, water pressure test, thickness test, PT (penetrant test), VI(visual inspect), X-ray test, dimensional check.
