1.Good thermal stability ,considering sudden heat and cold working condition,we apply special raw materials.
2.Good ablility to anti corrosion.impact to ensure reliabiliyt of product quality.
3.Anti-strong acid ,anti strong alkali .impact resistance:graphite crucible can with stand strong heat impact ,therefore your can use it fore any workmanship process.
4.Good thermal conductivity:Due to its high thermal conductivity ,you can shorten melting time, saving energy.
5.Ash contents is less than lting metal can not be polluted during melting process.
Application:All kinds of round complex geometric gasket is widely used in pipes, valves, pumps, pressure vessel, heat exchanger, condenser, generators, air compressor, the exhaust, chiller, etc.
Usage:Various shapes are available, used in petrochemical, mining, vessels, boilers, piping and duct, pumps and valves, flanges etc.
