RPM pushing pipe
For RPM pushing pipe,fiberglass as the reinforment material,the thermosetting resin as the matrix,and the high quality silicon sand or nonmetal granule as filler its connection type is equal diameter inserting type or steel sleeve type or steel sleeve type，and formed by fixed length winding process.
1. The excellent characteristics of RPM pushing pipe
(1) Light weight,high strength
(2) Installation easily,the pushing force of the pushing pushing pickax is decreased comparatively.
(3) No sinkage of the end of the RPM pushing pipe,easier to correct the deviation.
(4) High production efficiency with low cost.
2. Classification
2.1 Basic classification method
The classification of the products is performed according to
the nominal diameter,pressure class,hoop stiffness and axial
pushing force,etc.
2.1.1 Classification based on the nominal diameter( DN )
Nominal diameter: DN 400 mm、DN 450mm、DN 500 mm、DN 600 mm、DN 700 mm、DN 800 mm、DN 900 mm、DN 1000 mm、DN 1200 mm、DN 1400 mm、DN 1600 mm、DN 1800 mm、DN 2000 mm、DN 2200 mm、DN 2400 mm、DN 2600 mm、DN 2800 mm、DN 3000 mm、DN 3200 mm、DN 3400 mm、DN 3600 mm.
2.1.2 Classification based on the pressure class (PN)
Pressure class: 0.25MPa、0.6MPa、1.0MPa、1.6MPa、2.0MPa.
2.1.3 Classification based on the hoop stiffness class (SNh)
Hoop stiffness class: 5000 N/m2、7500N/m2、10000N/m2、12500N/m2、15000N/m2.
2.1.4 Classification based on the axial pushing force class( FD )
Axial pushing force class: 30t、50t、80t、100t、120t、150t、2000t.
Note: For the special requirement is agreed by the purchaser and the seller.
