Description
TP full flexible central drainage hose
Flexible Steel Pipe Systems for the Petrochemical and Refining Industry
The central drainage system refers to the equipment that discharges the accumulated water on the floating roof to the outside of the oil tank during the operation of the outer floating roof tank. The central drainage system is the most important part of the oil tank accessories.
TP full-flexible central drainage hose consists of a single hose, that is, from the float sump connecting pipe flange to the flange at tank wall drain outlet is a whole continuous drainage hose. Its structural characteristics are as follows:
The hose is vulcanized from nitrile rubber, spring steel wire and polyester fiber：
A: The outer layer of the hose is black synthetic rubber, which has good wear resistance, oil resistance and corrosion resistance.
B: Polyester fiber, wrap-around distribution ensures hose strength.
C: Two layers of spring wire wrapped around the hose to pre-deform the hose. It can conduct static electricity.
D: Polyester fiber, wrap-around distribution ensures hose strength.
E: The main material of the hose is black nitrile rubber. The nitrile rubber has good water and oil resistance and can work continuously in medium of -40℃- 100℃.
F: Stainless steel protective cover or polyester wear-resistant protective cover, free to bend and stretch, to ensure the safety of the outside of the hose.
