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:
DIN17175 seamless cold drawn steel tube (carbon steel, alloy steel), applies to seamless tubes including tubes for headers of heat-resistant steels which are 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.
Applications:
1. construction of boilers, boiler flue
2. pipe-lines
3. pressure vessels
4. 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.
5. superheater service
6. air preheating pipe line
7. superheater
Competitive Advantage:
