Matured processing craft ship

1. The equipment welds are manufactured in strict accordance with the welding process requirements. The welding personnel are certified welders for special equipment. The welding shape is beautiful and the quality of the welds is guaranteed.

2. The heat exchange tank pipe head is welded with an automatic tube plate welding machine, and the welds are inspected by PT-100% or MT-100%.
3. For pipe heads that require strong expansion joints, the pipe holes are grooved using CNC grooves to ensure the accuracy and surface quality of the grooves. The expansion joint adopts hydraulic expansion pipe, which ensures tight connection and reliable quality.

3. The tube sheets and baffles are processed using a CNC machining center with drills to ensure the position and size accuracy of the tube holes, and remove burrs at the tube mouth to minimize scratches on the heat exchange tube wall during the tube penetration process.
Heat exchangers are designed, manufactured, inspected and accepted in strict accordance with industry standards. Equipment that requires manufacturing and inspection requirements such as base metal test plates, welding test plates, material retests, heat treatment, non-destructive testing, hydraulic and air pressure tests, air tightness tests, leakage tests, etc. must be implemented in accordance with the standards to the letter. Each process of heat exchanger design, manufacturing, inspection and acceptance has witness data and is compiled into factory data.
