INSPECTION AND TEST:
CHEMICAL COMPOSTION TEST. MECHANICAL PROPERTIES TEST(tensile strength, yield strength, elongation, flaring, flattening,impact, etc). SURFACE AND DIMENSION CHECK. NON-DESTRUCTIVE TEST(eddy current test/ultrasonic test), HYDRAULIC TEST.
Description:
Mainly used in the construction of boilers, pipe-lines, pressure vessels and equipment for service up to 600℃ and at simultaneous high pressures, where the total stress and the relevant scaling conditions can raise or lower the temperature limit.Boiler tube and superheater service. Boiler flue, air preheating pipe line, superheater, etc.
Applications:
1. construction of boilers,
2. pipe-lines,
3. pressure vessels
4. equipment for service up to 600℃
