Products introduction

??

1. They are applied to the pipe network system whose transmission medium temperature is not higher than 120℃, accidental peal value is not higher than 140℃?and working pressure is not more than 2.5Mpa. Polyurethane thermal insulation pipes can work for at least 30 years continuously under the environment of 120℃.

?

2. The products are widely applied to the fields of heating and cooling, anti-corrosion and thermal insulation pipes engineering in the field of crude oil transportation.?

??

Production capacity

?

1. 5 polyurethane prefabricated directly buried thermal insulation pipe production lines, and they can produce 7000km DN20-DN1600mm polyurethane thermal insulation pipes each year;

?

2. 2 'one step' workmanship polyurethane prefabricated directly buried thermal insulation pipe production lines, can produce 3000 km DN30-DN300mm one-step polyurethane thermal insulation pipes each year.

?

Note: φ159, 3m/min, 8h each shift, each shift can produce 1440m; φ76-89, 5m/min, 8h each shift, each shift can produce 2400m;

?

3. The yearly production capacity of polyurethane prefabricated directly buried thermal insulation pipe fittings (elbows, tee joints, reducer pipes, fixed knots, etc.) is 10,000 pieces each year, and the production range is DN20-DN1600mm.

?

?Products advantages

?

1. The thermal insulation is good, the thermal loss is low, the thermal loss is only 25% of traditional pipes, a great amount of resources can be saved and the energy costs can be decreased significantly when running for a long time;

?

2. The products can have very strong waterproof and corrosion resistance capacity and relatively high mechanical strength, which can satisfy the thermal stress requirements of directly buried and laid installation without compensation;?

?

3. The operation and service life is more than 30 years, and correct installation and use can make the network maintenance costs extremely low;

?

4.??Piping trench doesn't need to be laid, and they can be buried underground directly. The construction is convenient and efficient, and the comprehensive cost is low;

?

5. The products can be directly buried underground, which is advantageous to the landscaping and town planning.?
