Polyurethane Spraying Foam Preinsulated Steel Pipe Making Machine Ideal for Preinsulated Pipe Manufacturing

Product Description:

Huashida's Innovation in Polyurethane Sprayed Polyethylene Thermal Winding Preinsulation Pipe Production Line

The thermal winding preinsulation pipe production line independently developed by Huashida is a cutting-edge technology comprising three key components: the External Shot Blasting and Derusting Collector Production Line, the Polyurethane Spraying Production Line, and the PE Winding Production Line. This integrated system has been granted several national patents, and its technological prowess has been acknowledged through a third-party standardized evaluation report, rating it at an advanced level of 5, placing it at the forefront domestically. Notably, it was honored as the first set of technical equipment in Shandong Province.

The production line is distinguished by its utilization of a continuous spraying production process, offering exceptional levels of automation, rapid production efficiency, cost savings through raw material conservation, enhanced foaming and closed cell rates, reduced water absorption, trinity molding, and heightened performance reliability. These features contribute to the creation of products that are not only environmentally friendly and low in carbon emissions but also provide substantial economic and social advantages.

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.
