Our Service
Drilling
BK metal offers drilling and machining service for steel tube and plate production, drilling is a critical fabrication in manufacturing boiler, cylinder and exchangers.
The accuracy of tube and plate processing, especially tube hole spacing and tube diameter vertical tolerance, surface finish are greatly affected by the above listed chemical equipment and practical performance.
BK metal is able to complete this job with high accuracy; we can handle any size and shape of tube and plate, round, half round, rectangular,etc.
U Shape Bending
BK metal offers tube bending service for heat exchanger project where U shape tube is used, tube can be bend to various radius configuration including 180°; tube ends are cut and trimmed; tube body is washed before packaged into wooden crate.
U shape tube shall go through tests stated by ASME and other specifications for wall thinning, The final quality of U tube is decided by both the quality of the steel tube and bending process.
Cutting
BK metal offers steel tube and plate cutting service for general needs for customized length and shapes, we can do both precise cutting for steel tube and plate that can be used directly in your project and cut to length with acceptable error range. CNC cutting and water jet cutting equipment are used to processing various tube and plates.We will fabricate and deliver you the work piece that can be used directly in accordance with your drawing, without extra processing.
Beveling
BK metal offers beveling fabrication for steel plate and pipes that need to be welded, beveled edges provide weld space for supporting weight and load on machine structures, bevel cutting equipments has various options: laser, plasma, oxyfuel, and waterjet, thermal cutting, abrasive cutting, and machining all take completely different methods to produce bevel cuts on plate, tube, or pipe.
CNC Processing
BK metal offers processing service by CNC machine tools,control part and tool displacement with digital information,to solve the problem of variable parts variety, small batch, complex shape, high precision and to achieve high efficiency and automatic processing.
Powder Spraying
Powder spraying The dry powder is adsorbed on the steel pipe using the principle of electrostatic spraying. After the high temperature barbecue of more than 200°, the powder solidifies into a solid and bright coating about 60 microns thick. Make the surface of the product smooth and uniform color with strong acid resistance, alkali resistance, collision resistance, wear resistance can withstand the erosion of strong ultraviolet radiation and acid rain for a long time without coating powder, fading, falling off and other phenomena.
