Our company produces ductile iron pipe can withstand high internal pressure during pressure testing, the experimental pressure than the international scale and European scales are higher than 1MPa. Ductile iron pipe also has good resistance to external pressure, can reduce tube bed and require the production of a protective layer, so that pipeline economical and reliable; another dn200 ductile iron pipe, zinc spray, spray paint asphalt, cement and other measures lining guaranteed within the casting, the external corrosion resistance. Zinc spray quality of my company's compliance with ISO8179 delineated, per square meter of the pipeline for the minimum amount of zinc spray 130g dn300 ductile iron pipe, asphalt paint thickness not less than 70μm dn400 ductile iron pipes, cement mortar lining comply with ISO4179 quality zoned fixed, guaranteed strong mortar chamber, smooth, strong adhesion. Ductile iron pipe, ductile iron pipe, ductile iron pipe applications where nature has iron, high performance, corrosion resistance of steel, ductile iron pipes can be a good, easy to install, mainly for municipal, industrial and mining water, gas, oil and other ductile cast iron pipe production technology since the 1990s from abroad, after digestion, absorption, improvement and innovation, are our high ductile iron pipe production specifications, to meet the diverse needs of customers, products, long service life, environmental health, is water pipes and more choice. dn400 ductile iron pipe, ductile iron pipe, dn500 ductile iron pipe is provided by virtue of Liaocheng Industry Co., Ltd.
