一步法生產線產品介紹：

該作業線是把絕熱層和防腐層同時包覆在鋼管外表面上，從而形成管道的保溫防腐層，
屬國內首創。與其他方法相比，具有連續作業、生產效率高、成本低、節約能源、無污
染環境等突出優點，經過技術升級，達到國際先進水平。 
工藝特點： 
1.可連續作業，生產效率高、成本低、 節約能源 
2.全自動糾偏，精度高、工作穩定、糾偏效果好 
3.作業線全部采用膠輪傳送，以防止對鋼管防腐層的損壞。 
4.夾克層與泡沫層粘結，泡沫層與防腐層粘接，防腐層與鋼管粘接牢固 
用一步法成型工藝成的管道絕熱防腐生產線自動化程度高，絕熱防腐層的質量完全符合
國家標準。 
該技術自研制成功以來，經過升級改進完善，目前已形成作業管線范圍達φ48mm～
φ426mm。主要用于原油輸送管道、直埋式供熱管和制冷系統管道的絕熱防腐，應
用前景十分廣泛，投資回報率極高，可應用于集中供熱單位、遠距離輸油、供水、供
氣等工程。 
One-step polyurethane insulating pipe production line
Product introduction:
The line is the insulation layer and anti-corrosion layer coated on the external surface 
of the pipe at the same time, so as to form a thermal insulation pipe anti-corrosion layer, 
a domestic initiative. Compared with other methods, with continuous operation, high 
production efficiency, low cost, energy saving, no environmental pollution and other 
outstanding advantages, through the upgrading of technology, reached the international 
advanced level.
Process characteristics:
1  Continuous operation, high production efficiency, low cost, energy saving
2  automatic correction, high precision, stable operation, good correcting effect 
3  Line all use rubber tyred transport, to prevent damage to the steel pipe anticorrosion layer.
4  Bonded jacket layer and the foam layer, adhesive foam layer and the coating, 
coating and steel bondingUsing the adiabatic anti-corrosion pipeline one-step 
molding process into the production line a high degree of automation, quality insulation 
coating in full compliance with national standards.Since it was developed, after upgrading
 to improve, currently has a range of working pipeline of phi 48mm phi 426mm. Mainly 
used for insulation and corrosion resistant pipeline, directly buried heating pipe and the 
cooling pipe system, has a very broad application prospect, high return on investment, 
can be applied to the central heating unit, oil, water, gas and other remote engineering.
