Description

Technical Field

[0001] The utility model relates to the technical field of polyurethane spray-wound thermal insulation pipe production, in particular to a pipe body stabilizing device used in a polyurethane spray-wound thermal insulation pipe production line. Background Art

[0002] Polyurethane spray-wound insulated pipe consists of a working steel pipe, a spray-coated polyurethane rigid foam insulation layer, and a wrapped polyethylene outer sheath. The process features a polyurethane insulation layer sprayed onto the steel pipe surface, followed by a polyethylene outer sheath secured to the outer surface by wrapping. This process not only improves insulation effectiveness but also enhances pipe durability and environmental friendliness. During production, the pipe body needs to be supported and rotated to facilitate the application of the polyurethane rigid foam insulation layer and the wrapping of the polyethylene outer sheath. Existing pipe support devices typically support the pipe body at both ends, then rotate it during processing to facilitate wrapping. However, this approach is inconvenient for processing at the ends and can easily contaminate the support components at the ends. To address this issue, a pipe stabilization device for polyurethane spray-wound insulated pipe production lines has been designed that supports and rotates the pipe body from the center of its interior. This solves the problems of supporting the pipe body from both ends, which makes processing difficult and easily contaminates the support components, thereby improving processing convenience and maintaining cleanliness.
