Novel polyvinyl chloride (PVC) pipe

Abstract

The invention discloses a novel polyvinyl chloride (PVC) pipe. In four surfaces of the square cross section of the PVC pipe, one surface is a plane, and at least one of the other three surfaces is a corrugated surface. A fire retardant and a flexibilizer are coated on the outer wall of the PVC pipe. The novel PVC pipe has the benefits that the PVC pipe is provided with the marble pillar-like cross section, so the current situation of the conventional round pipe or rectangular pipe is completely broken through, and the novel PVC pipe has small occupied space and can be perfectly combined with buildings.

Description

technical field [0001] The invention relates to a novel PVC pipe material. Background technique [0002] At present, with the development of science and technology, PVC materials are also widely used in many fields, such as drainage pipes, door and window profiles, etc., because of their light material, flame retardant, good acid and alkali resistance, low price, and convenient installation. , At present, it has gradually replaced metal pipes. However, the cross-sections of existing PVC pipes are all circular or rectangular. The circular pipes take up a lot of space and have different architectural styles from the flat walls. The cross-sectional forms of the rectangular pipes are too monotonous to match the increasingly rich architectural shapes. Contents of the invention [0003] The technical problem to be solved by the invention is to provide a new type of PVC pipe. [0004] In order to solve the problems of the technologies described above, the technical solution ado...

Problems solved by technology

However, the cross-sections of existing PVC pipes are all circular or rectangular. The circular pipes take up a lot of space and are different from the architectural style of the flat wall. The cross-sectional form of the rectangular pipes is too monotonous and cannot match the increasingly rich architectural shapes.
