What are the characteristics of a flat welding flange?

Flat welding flanges are those connected to vessels or pipes through angular welding. Flat welding flanges are widely used for the connection of medium and low-pressure vessels and pipes. The production process of flat welding flanges includes pure material forging, wool forging suitable for flat welding and butt flanges, steel plates for flat welding flanges, and centrifugal casting and cast flanges.

The flat weld flange saves space and weight completely, and most importantly, it ensures that the joints do not leak and have excellent sealing performance. The diameter will re-seal the cross-section of the face.

Next, the法兰垫圈 has been replaced by a sealing ring to ensure a perfect match between the sealing surfaces. As a result, only minimal pressure is needed to compress the cover. This reduction in pressure allows for the downsizing of bolt dimensions and the quantity required, leading to the development of a new product with a compact size and light weight (up to 70%-80% lighter than traditional flanges). Consequently, the flat welding flange is a relatively high-quality flange product that reduces both weight and space, playing a crucial role in industrial applications.
