? application:
? after jackup rig finishes well drilling, pile shoes should be pulled out f moving the pile leg, mud around pile shoe should be flushed off by using high-pressure seawater so as to facilitate pile pulling. jetting hose is high-pressure flexible connection between main deck of platfm seawater pipe line among pile legs.
? hose structure:
inner rubber: synthetic rubber mainly consisting of nitrile rubber which is oil resistant, seawater resistant, high temperature resistant ageing resistant
reinfced layer: high-intensity steel wire
outer rubber: synthetic rubber mainly consisting of chloprene rubber which is antiflaming, wear resistant, oil resistant, ozone ageing resistant ultraviolet light applicable to marine environment
? temperature range: -30℃ to +100℃
