Description

Flat welding flange refers to a flange connected with vessels or pipes by fillet weld. It is an optional flange. According to the integrity of the connection between the flange ring and the straight cylinder section, the design shall be checked according to the integral or loose flange. There are two types of flange ring: with neck and without neck. Compared with the neck butt welding flange, the flat welding flange has simple structure and less material, but its rigidity and sealing are not as good as the neck butt welding flange. Flat welding flanges are widely used for the connection of medium and low pressure vessels and pipelines.

Applications

Purpose and advantages of flat welding flange:

1. It is applicable to the connection of steel pipes with nominal pressure not exceeding 2.5MPA.

2. It is applicable to the connection of ordinary steel pipe or low alloy steel pipe with nominal diameter not exceeding 40mm.

3. It is applicable to low temperature pressure vessels with working temperature ≤ - 40 ° C~+400 ° C (L-NPS).

4. It is applicable to various industrial plants and production sites where the medium is non-toxic, non-corrosive and non-radioactive, and where corrosion and leakage prevention are required;

5. It is used to transport expensive, flammable, explosive media or media containing high concentration of hydrogen sulfide, carbon dioxide, water gas and other harmful gases.

6. For long-distance pipelines of combustible gas or liquefied petroleum gas that are not suitable for threaded connection in flammable and explosive places, directly buried prefabricated insulation pipes can be used.

7. It is applicable to galvanized plastic spiral corrugated compensator for water supply in high-rise buildings and indoor hot water pipeline system.
