Heat Exchanger Stainless Steel Boiler Pipe
TPCO Boiler Tube and PipeGrade: 304H, 310H, 321H, 347H, 347HFG
Specification:
ASME SA213: Standard Specification for Seamless Ferritic and Austenitic Alloy-Steel Boiler, Superheater, and Heat-Exchanger Tubes
The specifications of ASME SA312, JIS G3459, EN 10216-5, DIN 17456, DIN 17458 are available.
Process Inspection:
1. Inspect single work-piece's dimension, levelness, bend
degree, hole size, hole location, etc.
2. Inspect the work-piece's welding result
Assembly Inspection:
After cleaning inspection is good, then assemble on set to inspect its overall levelness, dimension, etc.Water Test:
Water test is a good way to check the distributor's working performance. The test items includes:
1. Liquid height in trough
2. Used time of one hole to fill the container
3. Calculate the coefficient variance(CV)
