Steel pipe difference:

1. Seamless steel pipe is mainly characterized by no welding joints and can withstand greater pressure.The product can be very rough cast or cold pick.

2. 15-16mm precision steel pipe is a product emerged in recent years, mainly with strict tolerance and roughness of inner hole and outer wall dimensions.

Features of 15-16mm precision steel pipe:

1. Smaller outside diameter.

2. High precision for small batch production.

3. High precision and good surface quality of cold-drawn products.

4. The cross area of steel pipe is more complicated.

5.15-16mm precision steel pipe has better performance and dense metal.

6. Steel pipes have superior performance and dense metal.

15 to 16 mm formula of precision steel pipe: :(outside diameter - wall thickness )* wall thickness * 0.02466 =kg/m (weight of per meter)
