A Flat welding flange is a kind of flange which is directly connected with equipment or pipeline through fillet weld. The structure is simple and easy to process. Its force characteristics between the whole flange and live flange, flat welding flange is divided into plate flat welding flange and neck flat welding two kinds of it, its cost is low, the production cycle is short, is the most commonly used type of a flange, widely used in a variety of fluid pipelines.
Classification
Flat welding flanges, necked flanges, butt welding flanges, ring joint flanges, socket flanges, and blind plates.
Material
Forged steel, WCB carbon steel, stainless steel, 316L, 316, 304L, 304, 321, chrome molybdenum steel, chrome molybdenum vanadium steel, molybdenum ditititanium, rubber lining, fluorine lining material.
Applications
Flange joints are an extremely common and widely used component in engineering design. It is piping design, pipe fittings valves essential parts, but also equipment, equipment parts (such as manhole, sight glass liquid level meter, etc.) in the necessary components. In addition, other professions such as industrial furnace, thermal engineering, water supply and drainage, heating and ventilation, automatic control, etc., also often use flange joints.

Production process
Production process is divided into forging, steel cutting, casting and so on. Among them, forging quality is the best price is the highest, the quality of steel plate cutting followed by the price is slightly cheaper, casting is the most inferior, the price is the cheapest. But the use of specific look at the use of the environment to purchase the right flange, not the more expensive the better.
What are the characteristics of flat welding flanges?
Flat welding flanges not only save space and reduce weight, the reason for the reduction in compact flange size is due to the reduction in the diameter of the seal, which will reduce the cross section of the sealing face. Secondly, the flange gasket has been replaced by a sealing ring to ensure that the sealing surfaces are matched so that only a small amount of pressure is required in order to compact the seal. As the required pressure decreases, the size and number of bolts can be reduced accordingly, resulting in the eventual design of a new product that is small in size and light in weight (70% ~ 80% lighter than conventional flanges). Therefore, flat welding flange is a high-quality flange product with reduced mass and space, which plays an important role in industrial applications.
What is the sealing principle of flat welding flange?
The two sealing surfaces of the bolts squeeze the flange gasket together to form a seal, but this can also lead to a breakdown of the seal. In order to maintain the seal, a huge bolt force needs to be maintained, so the bolt should be made larger. Larger bolts must be matched to larger nuts, which means that larger diameter bolts are needed to create the conditions for tightening the nut. But the larger the bolt diameter, the larger the applicable flange becomes bent, and the only way around this is to increase the wall thickness of the flange parts. The entire unit would need to be large in size and weight, which becomes a particular problem in the offshore environment, where weight has always been a major concern. Also, fundamentally, a flat weld flange is an ineffective seal, requiring 50 per cent of the bolt load to squeeze the gasket, leaving only 50 per cent of the load to maintain pressure.
