1 - Oil Discharging and Sucking Rubber Hose
Purpose: Used to suck or convey normal temperature gas, kerosene,
diesel oil, heavy oil, engine oil or other mineral oils.
Characteristics: It has a dual function of withstanding positive
and negative pressure; the hose body is solider and more adaptable to
service condition.

2 - Coast Oil Conveying Rubber Hose
Purpose: It is applicable to convey crude oil, gas, diesel oil,
kerosene and other mineral oils between oil tanker and wharf.
Application temperature is -20 ~ +80℃.
Characteristics: Rubber hose can withstand positive and negative
pressure. There are metal flange joints at each ends of hose and
convenient for use. The rubber hose is made of high quality oil
resistant rubber, which can be used in complex conditions for its solid
body, less distortion and higher tensile resistance.
There are two types of metal fittings, buried and assemble, that must be
determined by the two parties (i.e. provider and demander) by means of
consultation. Nominal inner diameter Maximum permissible tolerance

3 - High Pressure Oil Resistant Rubber Hose
Purpose: The rubber hose is applicable for sucking or conveying
crude oil and petroleum series products in temperature -20℃ ~ +80℃, as
well as sucking and conveying oil-based mud (-40℃~+100℃).
Characteristics: The enhancement layer of rubber hose is made of
steel wire resulting in double feature of bearing positive and negative
pressure, vacuum is less than 80KPa（600mm Hg）, working pressure is not
more than 3Mpa. The bursting pressure is less than four times of working
pressure. Reference weight
