DELIVERY CONDITION:
+N: after the final cold drawning, operation the tubes are normalized in a controlled atmosphere.
INSPECTION AND TEST:
CHEMICAL COMPOSTION TEST. MECHANICAL PROPERTIES TEST(tensile strength, yield strength, elongation, flaring, flattening/drift expanding, hardness, etc). SURFACE AND DIMENSION CHECK. NON-DESTRUCTIVE TEST(eddy current test/ultrasonic test), HYDRAULIC TEST.
Description:
EN10305-4 is seamless cold drawn steel tubes of circular cross section used in hydraulic and pneumatic power systems. Tubes according to this part of EN 10305-4 are characterized by having precisely defined tolerances on dimensions and a specified surface roughness. The allowed pressure rates and temperatures are the responsibility of the customer in accordance with the state of the art and in application of the safety coefficients specified in the applicable regulations, codes or standards.
