Notes
For PP / HDPE lined products medium duty ERW steel pipes conforming to IS: 1239 'B' class are normally used. Seamless pipes are used on special request.
Flanges are drilled to ANSI B 16.5 ASA 150 class dimensions. Other drilling standards are available on request at extra price.
Thickness of flanges is as per house standard.
Tolerance
Flange drilling dimensions + 1.5mm Dimensions of pipes and fittings + 3mm Flange thickness + 1mm
