Frequently asked questions

Are the flanges compatible with Russian DN standards?
Yes. We machine PN16 flanges to EN 1092-1 with the same bolt circle as GOST 12820, and can supply DN-from-DN15 with matching gaskets.

Can I replace the seats without removing the line?
On flanged two-piece bodies the centre section splits after the flange bolts are released, so seats and seals can be exchanged with the pipe supported in place.
