Frequently Asked Questions

What is the main advantage of the "loosing flange" design?
The loosing flanges can be freely rotated around the pipe axis before jointing, which makes alignment and installation much easier and more flexible compared to fixed flanges.
What materials are used in these fittings?
Both the body and the loosing flange are made from high-quality Ductile Iron grade 500-7 or 450-12 in accordance with the ISO 1083 standard.
Which international standards do these fittings comply with?
Our fittings are manufactured in strict accordance with ISO 2531, EN 545, and EN 598 standards, with flange drilling following ISO 7005-2/EN 1092-2.
What types of surface coatings are available?
We offer Zinc and Black Bitumen coating, Red or Blue Epoxy coating, and PU (polyurethane) coating to ensure maximum corrosion resistance.
Are accessories like bolts and gaskets included?
Typically, gaskets, bolts, and nuts are supplied separately from the fittings unless specifically requested otherwise in the requirement.
Do you perform pressure testing on all products?
Yes, we conduct a 100% water pressure test on all fittings to ensure integrity and compliance with safety standards before they leave the facility.
