What is the difference between Plate Welding Flange and Hubbed Slip on flange?

Slip On Plate Flanges: the sealing surface is raised face, which can be used for general media, medium and low pressure occasions.

Slip On Flanges:The sealing surface can be convex, concave and grooved. The pressure bearing strength varies withthe sealing effect. It is usually used in medium and high pressure occasions, such as corrosive, highly toxic, flammable and explosive occasions.

Plate-type flat welding flange looks like a simple component, but it can be widely used in every field.

What is its role?

Plate-type flat welding flange is generally referred to as tablet computer, and also referred to as lap welding flange. The connection between the flat welding flange and the pipeline is to insert the pipeline into the internal thread of the flange plate to a proper position, and then lap weld.

Plate-type flat welding flange is applicable to pipeline system software with low working pressure level and low fluctuation, vibration and fluctuation of working pressure. The advantages of flat welding flange depend on its easy alignment during electric welding and installation, and its cost is relatively cost-effective, so it is widely used.

A good feature of plate flat welding flange is its strong sealing characteristics. Sealing characteristics combing refers to the result that every object has a certain type of characteristics based on certain things, and then release such things have such characteristics.
The small structure of plate-type flat welding flange can have key parts, which can be trusted.

The raised face of the flat welding flange can be made into three types: smooth type, convex and concave type and tenon and groove type; The use of smooth flat welding flange is large. It is mostly used in situations where the material standard is relatively relaxed, such as bottom pressure non-purified air compression and bottom pressure cooling circulating water. Its advantage is that the price is more cost-effective.
Butt-welded steel flange plate: It is welded with flange plate and pipeline by professional butt welding. Its structure is reasonable, its compressive strength and bending rigidity are large, and it can withstand ultra-high pressure, continuous bending and temperature fluctuations, and its tightness is reliable. The butt welding flange with the pound grade of 0.25~2.5CPa adopts convex and concave raised face.

Plate flat welding flange and neck flat welding flange are different in application, so we need to compare them:
The slip-on welding flange with neck is imported from overseas, and is mainly used for natural gas valves, natural gas pipelines, etc. Because there is a short neck, it can improve the bending rigidity of the flange and improve the bearing capacity.
Plate type flat welding flange is used for general materials.
The flat welding flange with neck is suitable for flammable materials, corrosion, toxic side effects and aspect ratio sites
Raised faces of plate-type flat welding flanges are all convex faces (RF). Raised faces of neck flat welding flanges can be convex faces, convex concave faces and tenon and groove faces.
The structure of the two is different, the actual sealing effect is different, and the compressive strength is also different.
