1. Special Coating Technology
By 1998, we developed a special coating technology, which coats a metallurgical melting bond to steel pipe inner surface, thus increases heat resistance, anti-corrosion, and life time.
By specially developed raw materials, and by our new coating technology, our Laying head pipe has the following features:
a) Anti-wear out
b) Wear out format is LINE wear, which will decrease the Laying head vibration, and form a better coil shape.
c) High temperature resistance
e) Extra long life, up to 12,000 tons, for dia 5.5mm, at 115m/s, steel grade s235jr.
f) Weight difference between each laying head pipes are less than 100 g, so the pipes are easy to be balanced.
g) Pipes are one-step formed with standard shapes, prefect smooth surface.
h) Roughness USA Standard: 3.2 to 5.0 or China Standard GB 3505, 3.2.
a) Suitable to horizontal and vertical laying head.
b) Suitable to ALL laying head with speed up to 120 M/S
c) Suitable to Wire Rod Mill supplied by Morgan, Danieli, Pomini, SMS, with better life over OEM's.
