18 Years Factory Flexible Discharge Hose - Expansion Joint with Sanwich Flange – East

Expansion Joint with Sandwich Flange

The expansion joint hose we provide is of complete reliability and safety and can withstand extreme working conditions. In the actual production of kinds we can manufacture any kind of custom hose.
The expansion joint with sandwich flange is be sued in drag head of TSHD and CSD and sand pump. This kind expansion joint can help to dredge pipes to reduce shock absorption. We can manufacture different inner diameter and length according to customer requirements.

INSPECT and 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)
-Vacuum 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 and 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.
The quantity of suction hose is 2 pieces or 4 pieces, so we can can use steel & wood pallet or wood box to pack.

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.
