    摘要: To provide a multiple coat metal pipe and its fabrication method having excellent corrosion resistance without deteriorating chipping resistance or splashing resistance, capable of being fabricated easily and capable of simply carrying out peel off operation owing to a weak peel off strength wherein corrosion resistance of an end working portion is not deteriorated, there is provided a multiple coat metal pipe which is a metal pipe constituted by multiplexing and coating a first layer including a resin having an adhesive force in respect of a surface treatment layer formed on an outer peripheral face of the metal pipe and capable of being extruded and a second layer provided on an outer peripheral face of the first layer, having a chipping resistance and capable of being extruded, wherein a peel off strength between the first layer and the second layer is 75 g/cm or less.

    摘要: An improved anti-corrosive material used to protect buried conduits from corrosion. The material is a multi-layered co-extruded, calendered, or laminated polyolefin. The material has an outer layer, or environment contacting layer, preferably comprised of a low density polyethylene having characteristically strong tensile strength and elongation properties to provide conventional protection from soil, water, air, or other potentially damaging elements. The material has a center layer preferably comprised of a high density polyethylene having superior tensile strength to provide a high density barrier between the outer layer and an inner layer. The inner layer, or conduit contacting layer, is preferably comprised of a low density polyethylene impregnated with a biocide, a volatile corrosion inhibitor (VCI), or both. The biocide and VCI are able to migrate through the low density polymer matrix but the rate of migration of the biocide is considerably slowed through the high density polymer and the VCI is essentially unable to penetrate it. Thus, the biocide and VCI are substantially prevented from escaping into the surrounding environment, but rather, are trapped within a “protection zone” immediately adjacent the conduit surface to provide extended protection against corrosion.

    摘要: Conventional coating compositions have the disadvantage of being insufficiently coatable and having an unsatisfactory environmental stress cracking resistance. Now a coating composition has been found which has both good coating processability and environmental stress cracking resistance. It comprises a multimodal ethylene polymer, which contains from 80 to 100% by weight of ethylene repeating units and from 0 to 20% by weight of C3-C10 &agr;-olefin repeating units, has a density of between 0.915 g/cm3 and 0.955 g/cm3, and is a blend of at least a first ethylene polymer having a first average molecular weight and a first molecular weight distribution and a second ethylene polymer having a second average molecular weight, which is higher than said first average molecular weight, and a second molecular weight distribution, said blend having a third average molecular weight and a third molecular weight distribution.
