Containerized pipe coating material |
摘要 |
An improved containerized pipe coating including coating material and the container therefor is the subject of the present invention. An asphalt coating material comprising 10% to 25% by weight asphalt and 75% to 90% by weight sand-lime aggregate is used to coat the weld joints of pipe previously coated with similar material along its length for corrosion protection. The weld joint coating material is delivered to a coating station in easy to handle small size containers. The containers comprise no more than about 5% of the weight of the material contained thereby and are constructed primarily from a material containing at least one of the members of the group consisting of polyethylene, polypropylene and polyethylene-polypropylene copolymer. The containerized material is placed in a chopper where it is reduced in size. The chopped mixture of particles are then melted and stirred until a relatively even mixture of a flowable liquid is presented. The mixture has enhanced physical properties as a coating material.
