Flange connection is an important connection mode in pipeline construction. The flange connection is easy to use and can withstand greater pressure. In industrial pipelines, flange connections are widely used. 321 blind flange is without bolt hole, malleable cast iron, it is not carbon steel flange.

For more than 100 years, construction organizations have relied on the unique experience of assembling ductile iron pipes more precisely, fittings, and other components when installing pipelines. The range is now supported by the needs of engineers around the world. Distribution of malleable iron products, fittings, and other pipe fittings are purchased by customers in more than 180 countries around the world who know they can trust the quality and range of threaded fittings and superior complement to construction organizations even if brass and bronze or stainless steel fittings, threaded fittings are a large assortment.
