OEM China Grapple Dredger - Tapered Floating Rubber Hose – East

Tapered Floating Rubber Hose

The dredge hose we provide is of complete reliability and safety which can withstand extreme working conditions. In the actual production of kinds we can manufacture any kind of custom hose.
Tapered floating rubber hose is one kind of floating rubber hose. The buoyancy layer reduce down from one side to the other side and it have a good flexible than other floating rubber hose. It is the third piece hose is floating hose pipeline which connect with TSHD dredger bow joint.
This kind hose provide installation efficiency and reduces the impact of wind and waves on the offshore projects. Shanghai Dredging Company, Guangzhou Dredging Company,Jan de Nul,Boskalis,Van Oord and other international dredging companies use this floating rubber hose extensively around the world.

INSPECTION & CERTIFICATES

We use modern technology to design and manufacture, and through rigorous field testing.
The following tests are to be conducted:
-Raw material test including natural rubber,tensile textile,rubber additive(inspection before entering warehouse)
-Hose dimension check including flange size and length
-Weight check
-Working pressure test(if specified,sampling)
-Bending test(if specified,sampling)
-Buoyancy test(if specified,sampling)

Our QC department will inspect each product and offer FACTORY INSPECTION REPORT before delivery. We can also invite the third party inspection agency to inspect according to customer requirements. The usual inspection agency include Classification Society of China(CCS),Norway-German(DNV-GL),United Stats(ABS),United Kingdom(LR) and France(BV).

PACKING & DELIVERY

Advantage: professional,efficient,economical and environmental
Duo to our products are large size and heaviness,normal we do not use packaging during shipping in order to reduce costs. So the professional packing skills are crucial,not only it need to protect our products,but also need to protect the containers,vehicles and personnel. Our core strength comes from years of work experience and a responsible attitude.

APPLICATION

Duo to the continuous development of dredging vessel,Trailing Suction Hopper Dredger(TSHD) and Cutter Suction Dredger(CSD) are the mainly dredgers in the world. Duo to complex construction conditions including coral,reef rock,granite and others,the armored discharge hose effectively solves these problems.The floating hose provide installation efficiency and reduces the impact of wind and waves on the offshore projects.
