Fixed and adjustable flanges
Flanged joints are rigid and are typically used in above ground applications. Due to the risk of excessive bending moments being imposed it is recommended that flanged pipework is NOT buried.
Benefits:
- Strength of DI supports external bending moment making it ideally suited for above ground applications
- High beam strength accommodates spans up to 16m.
- No risk of performance loss through UV degradation
- Wide range of flanges available in PN10-PN40.
Fixed Flanged Joint Sets:
Joints sets are available to order for use with fixed flanges, these sets contain all components required for fixed flanged joints.
- IBC gasket 80º IRHD hardness
- Mild steel (grade 4.6) bolts, nuts and washers coated to water industry specification (WIS) 4-52-03
EPDM gaskets are supplied for use with potable water and Nitrile for sewerage.
Note that:-
On installations where flanges are required to be assembled in accordance with CESWI 6th Edition it may be necessary that longer bolts may be required. For more information contact:-

Adjustable Flanges
Saint-Gobain are able to offer adjustable flanges on a range of fittings in DN 80 to DN 600. On a selected number of flanged fittings Saint-Gobain will provide adjustable flanges as the standard product range please refer to the product catalogue for detail.
Fittings with adjustable flanges are jointed in a very similar way to fixed flanged fittings. The adjustable flange is mounted on to the main body of the fitting. The flange is then capable of rotation to align bolt holes. Saint-Gobain can also offer an additional range of flange fittings with adjustable flanges, please contact technical sales department for further information on Tel 0115 9300650/700
The key benefits offered by adjustable flanges are time & effort saved on site, particularly above ground or in pumping stations/treatment works.
- Adjustable for easy alignment if flanges are off-set
- Able to quickly change flange to higher/lower rating
- Metal insert gasket
- Mild steel bolts, nuts and washers
- Joints sets are available to order for use with adjustable flanges uti DN 300, these sets contain all components required for fixed flanged joints.
- DN 350 - DN 600 gaskets and bolts supplied separately
