Frequently Asked Questions About Lined Reducers & Flanges
Which lined reducers and flanges does Ambica Machine Tools manufacture?
We manufacture concentric and eccentric lined reducers, lined reducing flanges, lined blind flanges and gasket / spacers. A jacketed option is available for the reducers.
What is the difference between a concentric and an eccentric lined reducer?
An eccentric reducer has an offset between its major and minor ends, shown as E in our dimensional table, while a concentric reducer sits on the same centre line.
What size range is available for lined reducers and reducing flanges?
Lined reducers and reducing flanges are made from 25 NB up to 250 NB on the major side, with many major and minor size combinations such as 100 x 80, 150 x 100 and 250 x 200.
Which sizes can I get in lined blind flanges and spacers?
Lined blind flanges and gasket / spacers are available from 15 NB to 350 NB. Spacers can also be supplied in various lengths.
Which lining materials are used for lined reducers and flanges?
Lining options are PTFE, PFA, FEP, PVDF, HDPE and PP, with a minimum lining thickness of 3 mm. Please mention your chemical and operating conditions when you enquire.
What is the maximum temperature for each lining?
PTFE and PFA are suitable up to 200°C, FEP up to 160°C, PVDF up to 130°C, PP up to 90°C and HDPE up to 70°C.
What materials are used for the body and flanges?
The body is available in DI, CF8 or CF8M. Fabricated bodies use IS 2062, ASTM A105, SS304 or SS316 for the flange, and WPB, SS304 or SS316 for the reducer.
What flange standard and test pressure do your lined reducers follow?
Flange connections are as per ANSI B16.5, #150 or as per customer requirement. Lined reducers and reducing flanges are hydraulically tested at 20 kg/cm² and all lined items are spark tested at 15 KVDC.
What are gasket / spacers made of?
Gasket / spacers are available in PTFE, PP or ETFE, in sizes from 15 NB to 350 NB.
Can you make custom reducers, flanges or spacers?
Yes. Special finishes, non-standard dimensions and custom requirements can be considered as per your application needs. Please share your drawing or requirement with us.
