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 is a kind of seamless cold drawn steel tube which used in construction of boilers, pipe-lines, pressure vessels, and equipment for service up to 600℃. It at simultaneous high pressures, where the total stress and the relevant scaling conditions can raise or lower the temperature limit. Under this standard, it contains carbon steel and alloy steel.
Applications:
1. boilers, boiler flue
2. pipe-lines
3. pressure vessels
4. equipment for service up to 600℃
Competitive Advantage:
Developing technology, advanced equipment. Always put quality on first consideration. Best price and Service!
