Stainless Steel Lap Joint Flange

Because stainless steel has good corrosion resistance,  it allows structural components to maintain the integrity of their engineering designs permanently.

Elite Piping Manufacture Co is a company specializing in loose flanges of stainless steel. Our products are of high quality and our services are in place. We are your best choice. You are welcome to communicate with us on related matters at any time.

Stainless Lap Joint Flange Composition

The ss lap joint flange can be decomposed into three parts: lining ring (flange), nozzle, and flange ring. The connection between the lining ring (flange) and the nozzle can be in many forms, including the overall flanging and welding connection of the lining ring and nozzle.

The Connection Of Stainless Lap Joint Flange

The stainless lap joint flange is just a loose flange on the flange or flange, so it is also called a free stainless steel flange. The loop stainless steel flange is not directly connected to the container or pipe. This connection method does not achieve the same strength as a one-piece connection. Loop stainless steel flanges are often used in small-size applications.

 Usage Of  Stainless Lap Joint Flange

The lap joint flange is a loose flange. When the flange ring deforms, it does not produce additional torque on the container or nozzle. It is easy to manufacture and install. It can be made of different materials from the container or nozzle, such as zirconium, which cannot be welded to steel. It is widely used in containers and heat exchangers. The flange ring can be made of carbon steel or low alloy steel, which can save precious metals.

However, the flange ring of the looper flange is thicker and can only be used in situations where the pressure is not high.

 Installation Of Stainless Lap Joint Flange

The new stainless lap joint flange has a simple structure and is easy to install. This flange structure is mainly composed of a looper flat bearing, a spring snap ring and a looper flange. The looper flat bearing and looper flange are both provided with grooves corresponding to the spring snap rings, and the edges of the slots are provided with smooth rounded corners to facilitate the installation of the looper flange.

When not working, the looper flange can be pressed down. At this time, the spring snap ring is compressed and retracted due to the force, and the looper flange slides out of the groove due to the force.

In the working state, the looper flange is lifted upwards, and the spring snap ring is compressed in the groove and contracts until the slot of the looper flange matches the spring snap ring, and it is installed in place.

Sealing Surface Type

The sealing surface types include basic types such as flat surface, raised surface, concave and convex surface, tongue and groove surface, and ring connection surface blue cover.

 Types Of Stainless Steel Lap Joint Flanges

Assembly of welding ring loop flange and pipe. When assembling, first put the flange on the pipe, then put the welding ring on the pipe end and weld it with the pipe.

Assembly of flange loop flange and pipe. During assembly, the flange is first placed on the pipe, and then a flanging ring is welded to the pipe end, or flanging is performed directly on the pipe mouth.

 Stainless Lap Joint Flange Advantages

The metals in contact with the medium are relatively precious (for example, zirconium, titanium, aluminum). If all precious metals are used, the cost of the equipment will increase significantly.

 The materials included in the flange pressure-temperature table are limited. Some materials cannot be found in the table, or their allowable stress is extremely low (such as non-metal), and there is no suitable flange size to choose from.

The body requires special processing and installation techniques, and the flange must be installed later. For example, glass-lined equipment, floating end flange, hook ring, etc. of floating head heat exchanger.

The Installation Precautions Of Ss Lap Joint Flange

 Be sure to put the flange on the pipe, and then flange or weld the ring, otherwise the flange will not be installed, resulting in wasted rework.

The chamfered side of the inner hole of the flange must be pressed against the flange or the welding ring, and cannot be installed backwards;

The sealing surface of the welding ring should face outside the pipe mouth and cannot be installed backwards.

 Application Of Stainless Steel Lap Joint Flange

The looper flange is a movable flange piece, which is usually matched with water supply and drainage fittings (the most common on expansion joints). Equipment is bolted.

 Maintenance Service

Stainless steel flanges will cause damage to the end face or sealing groove during long-term production and operation, resulting in leakage accidents.

Slinlik flange repair technology and high-precision fully automatic professional equipment are used to completely eliminate leakage points and leave no safety hazards. And the repair time is short; the use of polymer composite materials can be repaired directly on-site to make the sealing surface meet the technical requirements of sealing, reducing disassembly, transportation time and costs.
