Audited Supplier Audited by an independent third-party inspection agency
It won the title of the first set of technical equipment in Shandong Province. The unit adopts continuous spraying or intermittent spraying production process. High degree of automation, fast production efficiency, saving raw materials, foaming closed cell rate increased, water absorption reduced, trinity molding, more reliable performance. Low carbon environmental protection and higher economic and social benefits.
Our company independently develops Polyurethane Spraying Foam Preinsulated Steel Pipe Making Machine, which consists of three parts: Steel Pipe Shot Blasting Machine, polyurethane spray production line, and PE winding production line.
Production steps:
Step 1: Rust removal on the outer wall of the steel pipe
Step 2: After rust removal, the steel pipe is lifted to the pipeline rack - it is transported to the spraying conveyor line by a pipe transport cart - the steel pipe is heated - polyurethane spraying - it is transported to the storage platform by a lifting cart - PE layer winding - water spray cooling - connection incision - finished pipe offline - finished pipe inspection - port repair - spray code packaging offline
1. 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.
2. 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.
3. Automated operation of production lines
Realize 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.
4. 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.
5. Efficient extrusion of pipelines
Using efficient and energy-saving extruders for extrusion, and using mechanical clamping devices for winding and compacting; Automatic cutting, triple cutting of anti-corrosion coating, automatic pipe removal during offline production, accelerating detachment.
6. Automated precision machining of pipeline interfaces
Centralize 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.
