HICL 10inch HDPE dredge pipe/hose

 General Description:

• The HDPE pipe for discharging sand/clay is a special plastic pipe, using high polymer and high density polyethylene (pressure-resistant, folding-resistant material), pressure-resistant material, anti-aging and uvioresistant material. It is most suitable for slurry discharging.

Advantage:

• The weight of HDPE pipe is light, only one-eighth of steel pipe. The pipes are connected with flanges, which makes the assembly, disassembly and transportation easier, shortens the starting time, raises the efficiency and avoid the troubles in replacement like the welded pipes.

• The HDPE pipe has good flexibility, tension, strength and elasticity. It doesn’t break after folding, extruding, or internal or external force impact. The pipes are connected directly and can be bended in water. The bending degree of 4 to 8 pcs of pipes can be 360 degree. It is of good resistance of storm and waves. On hand, the pipes can be connected even in area with 30 degree unevenness.

• The HDPE pipe has good wear-resistance, which is 4 to 8 times of steel pipe. so it lasts longer. The material is of high corrosion resistance to be float in sea water for 50 years, also it is uvioresistant, anti-aging and it can be used for five to eight years.

Dredger Launching Site is Available in our Shipyard 

In order to guarantee good performance and safety of our cutter suction dredger, all our products will be tested at the launching site before ex-factory, it is tested like the machine working in the customer’s working site. Performance and safety will be tested and recorded in the testing process. Usually, the buyer can also supervised the testing process before dismantle the dredge.

A. Preparing work before Dredger Testing

1)  Customers will be invited to watch dredger test , radio and pictures will email to buyers.

2)  Every parts and connections of dredger should be checked strictly before test. 

3)  Oil and cooling water should be ready for dredger test.

B. Dredger Test Contents 

1). Work condition of electricity connection of dredger should be checked .

2). Emergency pump to check operation conditions of hydraulic controlling system, 3). The speed and power of diesel engine should be tested 

4). Dredging pump will be tested and rotates at different speed with fresh water.

5). In order to check the operation of various hydraulic machinery and values, the main hydraulic pump will be opened and hydraulic system load performance should be tested.

C. After Testing   

    1).  All equipment performances and testing recorded will be printed as report for customers' reference.
