 Low working pressure
DPL 175 Welded Inslated Cylinder's nominal working pressure is 1.4Mpa.Setting pressure is 0.7-0.8Mpa,which are very low from the charging pressure of the high pressure gas cylinder.
Keeping medium's purity
DPL 175 Wwlded Insulated Cylinder prenvents the mixture of water,rust and gaseous impurity inthe ordinary cylinder and the purity is stable,which keeps the high quality of the stored medium.
Significant social and economic benifits.
One DPL 175 Welded Insulated Cylinder equals to twenty two high pressure gas cylinder,the weight ratio of medium to cylinder body decreased from 1:6.99 to 1:0.84,which can save large quantity of steel,decrease transportation fees and minimize pollutions caused by transportation.
