Note: 1. the above deviation is not suitable for normalizing, tempering or quenching and tempering of steel pipes.

the general size of the heat pipe is outer diameter: 38.1-273.0mm wall thickness is equal to 3%D (minimum 2.41mm).

3.The outer diameter deviation of the larger size steel pipe is determined by the supplier and the buyer.

Coating

1. When specified, the steel pipe prior to shipment should be greased to prevent corrosion 
2. If shipped predetermined order not coated with anti-rust oil steel, coating layer of oil production should remain on the surface 
3 If the provisions of the order does not need oiling Party shall be liable to rust during transport. unless otherwise specified, any manufacturer can be both inside and outside the steel surface coated with anti-rust oil.

surface quality

No folding, cracks, cracks and other defects are allowed to support inspection.
