Application
♦ Chemical
♦ Medicine
♦ Beverage
♦ Iron and steel
♦ Water supply
♦ Electricpower
♦ Water treatment
Installation Notice
Installed at the lowest point and vertical upward direction Install exhaust valve at the downstreat of flow meter
Don’t install at the highest point and vertical downward diection when drop is more than 5m
Installed at the lowest point when used in open drain pipe Need 10D of upstreat and 5D of downstreat
Dont’ install it at the entrance of pump, install it at the Installed at the rising direction

Applications
|
|
Stainless Steel 316L
|
Applicable in water,sewage and corrosive mediums.Widely used in industries of petrol,chemistry,carbamide,etc
|
|
Hastelloy B (HB)
|
Having strong resistance to hydrochloric acid of any consistance which is below bioling piont.
Also resistable against vitriol,phosphate,hydrofluoricacid,organic acid etc which are oxidable acid,alkali and non-oxidable salt.
|
|
Hastelloy C (HC)
|
Be resistant to oxidable acid such as nitric acid,mixed acid,as well as oxidable salt such as Fe+++,Cu++aStnd sea water
|
|
Titanium
|
Applicable in seawater,and kinds of chloride,hypochlorite salt,oxidable acid (including fuming nitric acid),organic acid,alkali etc.
Not resistant to a pure reducing acid(such as sulphuric acid,hydrochloric acid corrosion.
But if acid contains antioxidant is greatly reduce corrosion.
|
|
Tantalum
|
Having strong resistance to corrosive mediums that is similar with glass
Almost is applicable to all chemical mediums.
Except for hydrofluoric acid,oleum and alkali.
|
|
Platinum-iridium
|
Almost be applicable in all chemical mediums except for ammonium salt.
|
|
Stainless Steel Covered
Tungsten Carbide
|
Applicable in mediums of no corrosive and low abrasion.
