Product Description Product DescriptionIndependently developed by HUASHIDA company, this polyurethane spraying and polyethylene winding pre-insulated steel pipe production line holds multiple national patents. Third-party standardization evaluation confirms its advanced technical level at Level 5, reaching the domestic advanced standard. This unit has been recognized as the first set of technical equipment in Shandong Province. It utilizes a continuous or intermittent spraying production process, characterized by high automation, rapid production efficiency, raw material savings, increased foaming closed-cell rate, reduced water absorption, integrated molding, and enhanced reliability, contributing to low-carbon environmental protection and improved economic and social benefits.Our company's independently developed Polyurethane Spraying Foam Preinsulated Steel Pipe Making Machine comprises three main sections: Steel Pipe Shot Blasting Machine, polyurethane spray production line, and PE winding production line.Production Steps:Steel pipe External shot blasting ----> PU foam spraying ----> PE film wrapping ----> water cooling ----> cutting down pipeline ----> trim end of pipe ----> printing mark & loading down finished pipe ----> sealing end of pipe1 Features Dust removal meets environmental standards:By adopting an intelligent shot blasting and rust removal scheme, the equipment can be opened sequentially and self-locked, the shot blasting motor can save energy through frequency conversion, the sand volume can be set according to the pipe diameter, the air washing system can clean the shot sand, and the plug type can quickly change specifications. The three-level dust removal meets environmental protection standards.Suitable for the production of large-diameter insulation pipes:By adopting a high load-bearing spiral conveyor line, the polyurethane foam spraying and polyethylene winding processes are continuously carried out, which has the advantages of high efficiency, energy saving, speed, and stability. It is suitable for the continuous production of large-diameter insulation pipes and saves investment in transportation equipment.Automated operation of production lines:Realizes automatic processing of upper and lower pipes. The conveyor line is equipped with upper pipe sensors, automatic acceleration tracking sensors, automatic acceleration detachment sensors, detachment confirmation sensors, and automatic descent sensors to ensure the automated operation of the production line.Spraying saves materials:The online spraying speed of pipelines is fast; Constant intermediate frequency power, infrequent on/off, minimal impact on the power grid, balanced temperature, and energy conservation; Continuous spraying saves raw materials, and the head and tail of the steel pipe are automatically connected to ensure consistent surface thickness during spraying.Efficient extrusion of pipelines:Utilizes efficient and energy-saving extruders for extrusion, and employs mechanical clamping devices for winding and compacting; Automatic cutting, triple cutting of anti-corrosion coating, automatic pipe removal during offline production, accelerating detachment.Automated precision machining of pipeline interfaces:Centralizes multiple processing steps on a single device for automated processing, achieving precise control over the size, angle, and blunt edge dimensions of the pipe opening.
