Cangzhou Bohai ocean with strong innovative design and technology R & D strength, first-class product performance, strong marketing capabilities, perfect after-sale system, pipeline transport all kinds of granular media are susceptible to wear and tear, especially in mining, coal and other industries, There transporting tailings and cinder high abrasion media work, must be used with anti-wear properties of the pipe. Current common wear pipe there are many, today briefly, wear the cast stone pipe tubing. Cast stone pipe manufactured from cast stone or cast stone and metal made of composite, cast stone pipe products mainly include cast stone pipes and cast stone composite pipes. ˉ pipe used in cast stone, is an artificial crystalline silicate processing, and it has good wear resistance, corrosion resistance, toughness and impact resistance but the performance is poor. Cast stone pipe advantages: cast stone pipe hard, Mohs hardness factor of up to 7-8 Mohs hardness, wear coefficient reached 0.09-0.14g / cm 2. Forming cast stone pipe in hardness only to wear-resistant ceramic pipe, its abrasion resistance higher than ordinary steel 5 to 10 times, can be used in various industrial sectors abrasive media delivery. Cast stone pipe has good corrosion resistance, particularly acid and alkaline corrosive media, the ability except hydrofluoric acid and a variety of other hot phosphoric acid and alkaline substances, more than 96% acid resistance, alkali resistance is higher than 98%, can be adapted to a variety of strong acid and alkali corrosion work environment. Cast stone pipe is made of industrial waste or natural rock as raw material manufacturing, raw materials rich in natural resources, low cost, and the production process is simple, there is a very good price. Cast stone pipe Disadvantages: ductile cast stone pipe drawback is poor molding process is not high, difficult to process. Cast stone pipe larger proportion of higher weight, for installation and maintenance have caused some difficulties. In addition, cast stone pipe thermal shock resistance is poor and can not be used for temperature changes in the workplace. www.hbthgg.com www.thgangguan.com www.naimoguanjian.com www.hbbgc.com www.naimogd.com www.hbbengguan.com www.bengguan168.com www.pvdfgc.com www.hbguandao167.com www.zgyhgd.com
