Carbon Alloy Steel Tube Precision Seamless Steel Tubes En10305-4 E235 Cold Drawn Piping
TORICH, located in Ningbo, Zhejiang Province, is a rich experienced maker in precision steel tube for standard of EN10305-1, EN10305-52, EN10305-4,etc.
1.Brief introduction od precision seamless steel tube:
Delivery: The tubes shall be delieved in the delivery consition +N which means that after the final cold drawing operation the tubes are normalized in a controlled atmosphere.
Production way: cold drawn seamless
Test: Tensile test, drift expanding test, dimensional inspection, roughness measurement, visual examination, leak tightness test.
2.Our main feature of carbon alloy steel tube precision seamless steel tubes:
Excellent brightness,
No oxidization on outer and inner walls after heat treatment,
High cleanness of inside wall,
No deformation after clod bending.
No crack after flaring and flattening.

6.Our packing ways of precision steel tubes:
Wooden case packing: it's the est way to ship precision steel tubes. They can anti-squeeze, anti-rain, anti-collision, etc by using wooden case.
Woven bags packing: The woven bag is usually packed in the shape of a hexagonal package, which is more stable and not easy to move in the container.
