| Application |
Because the flange has good comprehensive performance, it is widely used in basic projects such as chemical industry, construction, water supply, drainage, petroleum, light and heavy industry, refrigeration, sanitation, plumbing, fire fighting, electric power, aerospace, shipbuilding, and so on. |
Face : Can be raised face ( RF ), full face ( FF ), Ring joint ( RTJ ), Groove , Tongue , or customized .
Bevel end as per ANSI B16.25
CNC fine finished .
Face finish : The finish on the face of
flange is measured as an Arithmetical Average Roughness
Height ( AARH ). The finish is
determined by the standard used . For example , ANSI B16.5 specifies face finishes within a range 125AARH-
500AARH(3.2Ra to 12.5Ra). Other finishes are available on requst , for example 1.6 Ra max ,1.6/3.2 Ra ,
3.2/6.3Ra or 6.3/12.5Ra. The range
3.2/6.3Ra is most common .
Marking _ and Packing
Each layer use plastic film to protect the surface
For all stainless steel are packed
by plywood case . For bigger size
carbon flange are packed by plywood pallet . Or can be customized
packing .
Shipping mark can make on request
Markings on products can be
UT test
PT test
MT test
Dimension test
