1.Advanced Technology of Cold drawn machine.
70 meters long cold drawn machine can produce 53 meters long for each pipe.+ Advanced technology for South Korea and Japan.It makes the more close dimension controls.
2.Advanced annealing Machine
A special bright annealing process,the heat treatment is performed in a so called closed furnace.The heat treated material is protected by an inter gas atmosphere,Which guarantees the Oxygen can not enter the furnace to contact with the materials.and react to form scale on or tarnish the materials.The surface finish is clean,bright and precision even for the tube with more than 24 meters.
3.Perfect Inspection Method &Equipment.
100%Inner cleaned by sponge
Detection equipments Max.30m
