FAQ
Can EN standard flanges and national standard or American standard flanges be used interchangeably?
Cannot be directly used interchangeably. The European standard implements the EN1092/DIN system, and the outer diameter, thickness, bolt hole spacing, and sealing face dimensions are completely different from national standards and American standards. Forced installation will result in problems such as incorrect hole positions, poor sealing, and equipment mismatch. Foreign-related projects and imported equipment must use dedicated European standard pipe fittings.
Which countries and regions are European standard pipe fittings suitable for?
Suitable for projects in EU countries as well as countries and regions in Southeast Asia, the Middle East, Africa, and elsewhere that adopt the European standard EN/DIN system. They are the mainstream standard pipe fittings in global foreign trade. If the country where the project is located adopts another standard system, please contact us to confirm whether production according to the corresponding standard is possible.
Can European standard flanged pipe fittings be customized with non-standard dimensions and special pressures?
Yes. We support customization of DN10 to DN4000 full-diameter European standard non-standard dimensions, special thickened wall thickness, irregular angles, and special reduction ratios, and the pressure rating can be customized across the full PN2.5 to PN100 series. Materials can be customized to European standard grades such as S235JR carbon steel, 304/316L stainless steel, and ductile iron. Please provide drawings or technical agreements, and we will assist with confirmation.
What are the delivery time and minimum order quantity for conventional specifications?
Conventional European standard general stock specifications support a minimum order of 1 piece, including PN10, PN16, and PN25 mainstream pressures and conventional DN small and medium diameter standard pipe fittings.
