Product Introduction

Plate Flange
The Plate Flange is suitable for connecting titanium pipes with nominal pressure not exceeding 2.5mpa. The sealing surface of the plate flange can be made into smooth type, concave and convex type, tenon groove type. The smoothed flush welding flange has the largest application amount. It is mostly used in the case of mild-medium conditions, such as low-pressure non-purified compressed air and low-pressure circulating water.

Threaded Flange
The threaded flange is connected with a thread. However, the center of the product has a thread size corresponding to the pipe.Its main advantage is that it can be assembled without welding.
Thread flange nominal size: DN8 ~ DN100 working pressure: 1.0 ~ 2.5 (MPa) plate.
Threaded flange application: applicable to fire, gas, hot and cold water, air conditioning, air pressure pipe, oil pipe, instrument, hydraulic pipe and other industrial.

Blind Flange(BL)
blind flange is the middle of the flange without hole, for sealing the pipe plug.There are many types of sealing surface, including plane, convex surface, concave and convex surface,tenon groove surface and ring connecting surface.

Weld Neck Flange (WN)
Butt flange: Weld Neck Flange is usually called “high hub” flange.Its purpose is to transfer the pressure of the pipe, thereby reducing the high stress concentration in the flange base.However, the price is high, because the production process is complex.

Sliding Flange
The sliding flange has a lower hinge as the pipe enters the single flange before welding.It is welded internally and externally to provide sufficient strength to prevent leakage.The sliding flanges are all bore to match the slightly larger outer diameter pipe.They are superior to the welding of neck flanges, due to the lower initial cost,but the final installation cost will probably not be lower because of the added welding of neck flanges.

Lap Joint Flange
The lap joint flange is actually identical to the sliding flange. Normally, lap joint flanges and lap stubs are together will be the system.

The Socket Welding Flange
The socket welding flange is a similar sliding flange unless it has a hole and reverse hole dimensions.The counter hole matches the pipe so that the pipe is inserted into the flange similar to the sliding flange.The diameter of the smaller hole is the same as the ID of the same pipe match.The limit is a built-in hole that sits at the bottom as a shoulder sleeve for the pipe.This eliminates any flow limitation in the use of socket welded flanges.

The welding ring loosens the flange cover
The welding ring loosens the flange cover is the flange piece that can move, it is form a complete set commonly on water supply and drainage fittings, both ends of the telescopic joint have a Lap joint flange when it be Finished before delivery ,it can connect directly with the pipe in the project, equipment with bolt.The purpose of loose flange plate with flat welding ring is generally to save materials. Its structure is divided into two parts. One end of the pipe part is connected with the pipe, and the other end is made into flanges.Flanges are made of low grade material, while the pipe part is made of the same material as the pipe, so as to save materials.

The welding ring loosens the flange cover:
1. Cost saving.When the pipe material is special and expensive, the cost of welding the flange of the same material is high.
2, not easy to weld or not easy to product.Such as plastic pipe,glass pipe and so on.
3. Convenient for construction.For example, it is not easy to align the flange bolt hole when connecting or prevent the change of the flange bolt hole when replacing the equipment in the future.

Defects of The welding ring loosens the flange cover:
1. Low pressure.
2. Low strength at the welding ring (especially when the thickness is less than 3mm)
