Packaging of Flat Flanges
Packaging: Flat Flanges is sleeved into plastic bag individually, ten pieces wrapped with water-proof material, bundled with nylon rope. Clear labels are tagged on the outside of the package for easy identification of the quantity and product I.D. Great care is taken during operation and transportation.
Prevent any damage.
During transportation items are tagged, packed in plastic bags and closed in carton boxes or seaworthy wooden cases.
plywood case,pallet and according to customer’s requirment
Marking:Flat Flanges are marked with alloy name, outside diameter, wall thickness and heat number. Additional information like standard and alloy numbers can be added on request.
flat flanges are used in less arduous applications, like low-pressure water piping. They are commonly used in low temperature and pressure environments such as pump suctions or water treatment flanges.
