Shanxi Chenhui Sinuoer Pipe Industry Co., Ltd

Shanxi Chenhui Snorre Casting Group Co., Ltd. is a large group company integrating mining, ore dressing, sintering, ironmaking and casting, with three smelting blast furnaces, twenty centrifugal units, five annealing furnaces and five automated finishing lines, and a total investment of two billion RMB. The company mainly produces ductile iron pipes, flexible cast iron drainage pipes, ductile iron fittings and ductile iron manhole covers. The overall annual production capacity is more than one million tons. Among them, the annual production capacity of ductile iron pipe is 500, 000 tons, specification: DN80mm-DN2600mm; The annual production capacity of flexible cast iron drainage pipe is 200, 000 tons, specification DN50mm-DN300mm; The annual production capacity of ductile iron fittings is 200, 000 tons, specification DN80mm-DN2600mm; The annual production capacity of ductile iron manhole cover is 100, 000 tons. Covering an area of 55, 000 square meters, the company has more than 4, 000 employees, with more than 1, 000 professional and technical personnel.

In order to ensure product quality, we have invested heavily in the establishment of a casting product testing center with metallographic room, spectral room, physical room, high temperature room, which is capable of comprehensive testing of casting pipes and fittings according to GB/13295-2019 and 1S02531, and the testing facilities and technology are at the leading level in the country. Scientific management, modern equipment, resulting in excellent quality, excellent products, can not be separated from scientific management, the company successfully passed the ISO9001 quality management system certification and product quality certification, but also passed the IS014001 environmental management system certification and OHSAS18001 occupational health and safety management system certification.

The company's products have been exported to the Middle East, Southeast Asia and South America market, at present, no matter the product quality, or after-sales service, are in the forefront of the industry. Our company produces centrifugal ductile iron pipe advanced technology, after annealing the outer surface of the pipe spraying anti-corrosion zinc layer, according to the international 1S08179 standard, the purity of 99.99% zinc wire hot-melt, curing spraying process, the thickness of 130g per square meter, by the national standardization committee of the professional laboratory test, the service life of up to 100 years. According to the international standard IS04179, choose common silicate 52.5 cement, quartz sand as raw material, add drinking water for mixing, using cement centrifuge high 2 speed rotating dewatering, so that the cement mortar in the inner wall of the pipe once curing molding, and quickly put into the steam pool for 8 hours of maintenance, so that the product to reach a higher standard. External anticorrosive asphalt paint coating according to 1S08179 or GB/T17456 requirements for control, the average thickness of not less than 70um, the wet state using a standard measurement card, the dry state using a thickness gauge measurement. The appearance of asphalt paint layer is required to be uniform, in line with the relevant provisions, according to different customer requirements, the company can be tar pitch spraying, epoxy asphalt spraying, epoxy resin spraying, polyurethane spraying and a variety of options, polyurethane is a new type of green special coatings to adapt to the needs of environmental protection and research and development, there is a good abrasion and corrosion resistance, to achieve the effect of double-layer corrosion, so that the ductile iron pipe in the underground by the The service life of the ductile iron pipe is doubled in the case of humidity corrosion.
