Spetech® Weld Ring Gasket RM4

Full size hollow lip weld-ring gasket (inside weld seam only available to flanges). Advanced construction recommended especially for large diameter joints. SPETORING® RM 4 is capable to compensate great axial and radial differential expansions; extremely resistant to thermal and pressure shocks.

If crevice corrosion is an important issue – than auxiliary inside seal should also be used. Typical thickness is 2x15mm (30mm for full seal). Customised crosssection and diameters are available (which allows to install this adopted/ customized weld ring seal using existing flanges with shapes ready for other types of seals: spigot recess, delta shape, double cone, etc...). Rewelding up to 4times (easy to dismantle with 2mm cut-off disc). Radial compensation up to 5.0mm. spetech.com.pl
