Problems solved by technology

[0002] In metallurgy, mining, electric power, building materials, refractory materials, energy and other industrial industries, the transportation of materials is carried by long-distance and powerful pipelines. Unable to meet this requirement, composite piping must be used
At present, composite pipes are mainly divided into steel-plastic composite pipes, which can only work at lower temperatures; self-propagating ceramic composite pipes, which have advantages in preparing straight pipes, and special-shaped pipes cannot be composited as a whole, and the influencing factors of the preparation process of this product are more complicated. , poor quality controllability; cast stone pipe - heavy weight, high brittleness, which brings difficulties to transportation, production, use and maintenance; lost foam vacuum suction casting bimetallic pipe - solves the problem that special-shaped pipes cannot be combined, but the weight is heavy It is the biggest defect of the pipe; the inner ceramic sheet has certain advantages in the preparation of large-diameter pipes, but the preparation of small-diameter pipes is limited to a certain extent
