Everyone knows that ductile iron pipe is a very good quality pipe, because it has the essence of iron, the performance of steel, which also makes its anti-corrosion performance very effective, the hardness is very good, and its ductility is also very Not bad. There are a lot of merchants selling spheroidal cast iron pipes in the market, and there are many counterfeit and shoddy products. How do we identify good ductile iron pipes? As a Ductile Iron Pipe and Fitting Supplier, we will share a few methods. To identify the advantages and disadvantages of ductile iron pipe.

1. Compared with a good drain pipe, the inferior pipe is mostly rust or reddish brown with no metallic luster. Moreover, the surface is prone to cracks or crusting. The main reason is that the material used is adobe, and the adobe has many pores. Once it receives the influence of external heat, it will be easy to crack.

2. Inferior cast iron drainage pipes are relatively weak and easily scratched. And there are often pockmarks. According to Shinko Casting, it refers to the fact that the groove is seriously worn, which causes defects on the surface of the drain pipe. Usually due to the blind pursuit of profit by Ductile Iron Pipe Fittings Factory, the rolling mill is over-standard.

3. Drain pipes with poor quality are prone to fold marks. It is a variety of fold lines formed on the surface of the drain pipe, which often runs through the entire product.
