DIN 86037 Flange : A Comprehensive Guide

DIN 86037 Flange Introduction

COPPERRY With 20+ years of manufacturing, we are industry-leading specialists in producing DIN86037 flanges. Having served numerous shipyards across China and worldwide.

Applications in Shipbuilding

The copper-nickel inner flange is designed for protection against seawater corrosion. Ensuring long service life and reliable performance.

Protection of Steel Flange:

It is treated with a hot-dip galvanizing process to shield it from the salty air onboard,  to hasten the rusting process.

Assembly and Sealing

DIN86037  inner flange and the hot-dip galvanized steel outer flange – are securely fastened with bolts, creating a superior seal.  DIN 86037 flange offers an efficient, durable, and cost-effective solution for shipbuilding requirements.   promise not only quality and performance but also the guarantee of longevity.

DIN8037 flange benefit

DIN86037 flanges are cheaper than copper nickel high neck flanges. DIN86037 flanges are loose-fitting flanges, the outer flange can be rotated , you can easily install the flange on site.

DIN86037 Flanges need to be insulated with gasket?

The din86037 flange is recommended to be fitted with an insulating liner. Copper nickel inner flange and carbon steel outer flange are two metals. Contact between two different metals will produce potential difference corrosion.

ps: potential difference corrosion is more serious than seawater corrosion.
