The company will be quality products DN400 ductile iron pipe, competitive price, good reputation sincerely welcome new and old customers to negotiate orders. After nearly 10 years of development, the domestic sphere cast-iron pipe quality cast-iron pipe is close to the level of developed countries ball. The so-called "near" and not "reach", that there is a gap. The main difference in the quality of the performance of cast-iron pipes inside and outside the ball and finish inside and outside coating. I had a few carefully observed certain production scale and high visibility of the domestic sphere cast-iron pipe manufacturers of products found to have a superficial appearance of slag, porosity and other defects dispersed gas pit DN500 ductile iron pipe, cast pipe wall with cracks, and even slag layer thicker. I believe that such defects ball cast-iron pipe, because the result of a lack of hot metal purity. "Hot metal purification" theory: the purity iron is internal to the product quality that the decisive factor. Therefore, to improve the purity iron ball is the key to producing high-quality cast-iron pipes, while the production of high quality ball prerequisite cast-iron pipe products to international markets.
