Custom S235JR Flanges for Danish Client: Precision & Durability from Haihao Group

At Haihao Group, we take pride in delivering tailored flange solutions that meet the rigorous standards of global industrial partners. Recently, we successfully fulfilled a comprehensive order for a Danish client, providing a full set of DN80 and DN150 S235JR flanges designed for alumina applications. This project highlights our expertise in manufacturing custom components that ensure reliable performance in demanding environments.

Precision Engineering for Every Application

The order comprised a diverse range of flanges, each meticulously crafted to exact specifications: DN80 Series (for steel pipe OD 121 x 4 mm):

Rotating Flange DN80 PN10-PN16 (Alumina): This component, weighing 2.6 kg, features a hot-dip galvanized finish for superior corrosion resistance. With dimensions of Ø200 OD, Ø160 bolt circle, and 8 x Ø18 holes, it is engineered for seamless integration and rotation in critical systems.

Flange Collar DN80 PN10-PN16 (Open & Closed): These collars, weighing 0.5 kg and 0.6 kg respectively, are designed for robust pipe connections. The open collar has an ID of Ø113, while the closed collar features an ID of Ø80, both with a 16 mm thickness and chamfered edges for precision fitting.

Fixed Flange DN80 PN10-PN16 (Alumina – Open): Weighing 2.7 kg, this fixed flange shares the same dimensional standards as its rotating counterpart, ensuring perfect compatibility within the system.

DN150 Series (for steel pipe OD 193.0 x 5.6 mm):

Rotating Flange DN150 PN10-PN16 (Alumina): This robust component, weighing 5.1 kg, boasts a larger Ø285 OD and Ø240 bolt circle, with 8 x Ø22 holes to handle higher pressure requirements.

Flange Collar DN150 PN10-PN16 (Open & Closed): With weights of 0.9 kg and 1.1 kg, these collars are designed with an outer diameter of Ø217. The open collar has an ID of Ø180, while the closed collar has an ID of Ø150, both featuring a 16 mm thickness for structural integrity.

Fixed Flange DN150 PN10-PN16 (Alumina – Open): Weighing 5.4 kg, this fixed flange mirrors the dimensions of the rotating DN150 flange, ensuring a complete and cohesive system.

Every flange in this order is manufactured from S235JR carbon steel, chosen for its excellent mechanical properties and weldability. The hot-dip galvanized coating provides an additional layer of protection against corrosion, making these flanges ideal for the harsh conditions often encountered in alumina processing and other industrial applications. Our strict quality control processes ensure that all surfaces meet a roughness standard of Ra 3.2, and all holes and edges are chamfered by 0.5 mm for safety and precision.
