EXPANSION JOINTS
Expansion Joint 'O' Ring Type (Class 150)
PTFE Expansion Joint “O” ring type
Flange Material:Forged as per ASTM A105, DI Casted as per ASTM A395
"O" Type ring Material: S.S.316
Limit bolt material: Carbon steel
All Dimensions are in mm and as per ANSI B 16.5 #150
PTFE as per ASTM D4895
Lining and testing as per ASTM F1545-15a
Roll Test:
Duflon Expansion joints are 100% roll tested before molded into convoluted form
In this test, the liner is compressed to 50% of its diameter in two different planes to detect liner defects
Hydro Test:
Duflon expansion joints are 100% hydrostatically tested prior to shipping
This ensures that the final product is free from defects
All expansion joints are hydrostatically tested at 1.5 times their pressure rating
Product Performance Testing
Flex Life Test: One expansion joint of each size is installed at neutral length on the flex tester and is flexed at
allowable compression and extension. One cycle is defined as neutral-compression-neutral-extension-neutral
Paint:Heat resistant black paint
We also offer Expansion Joint in Stainless Steel flange material
Neutral length dimension from PTFE face to face
Note:Maximum (axial) travel is based on installation with no misalignment or angular deflection
WARNING:
1. Safety shields must be used at all time in hazardous service to protect against serious personal injury, in the
event of expansion joint failure.
2. Liner sleeves must be used in abrasive service or where sharp- edged solids are or may be presentWarranty:
All goods sold here under are warranted to be free from defects in materials and workmanship for a period of one
year from initial use but not exceeding 18 months from date of shipment
