Lap Joint Flanges

Lap Joint Flanges:  Promoting connections and enhancing performance by the use of technology which leads to the provision of more inclusive and effective arts and cultural scenes.

Lapping joined Flanges is the flange type typically seen in industrial pipeline engineering mainly due to their very peculiar design and function. They consist of two main components D-shaped flask with a flatchfaceed flange ring and a stub end. The inner surface of the lap flange ring is curved, and that of an illustration of the stub end is flat. When these two, subject to primitive handcraft, are interconnected, the result is quite a loosely joint that can be tightened or loosen.

Benifits of Lap Joint Flanges

Cost-Effective Solution: Becoming more main stream, Lap Joint Flanges Supplier are usually less expensive than other flange types. Removing stub end and re usage during the job of replacing or modifying pipes may be a cause of significant expenses saving.

Lower Stress Concentration: The slip fit which the flange ring has in a lap joint flange is meant to spread the bolt load over the entire area as opposed to stress accumulation in one locality. This mechanism provides the additional integrity and a longer-life span to the tire.

Applications of lap joint flanges

Following are applications of Lap Joint Flanges:

  • Transporting materials
  • The Automotive Industry
  • Homes and Buildings
  • Sewerage systems and an industrial water lines installation system.
  • Heating and air-conditioning equipment
  • Plumbing
  • Food Processing Industry
  • Paper & Pulp Industry

To name just a few we have the Food Industry, Retail, and Clothing.

Properties of Lap Joint Flanges

Easy Alignment and Installation: Bringing under the spotlight the characteristic of known lap joint flanges, which is the possibility to make the assembly easy, is another facet of this advantage. The inclusion of a lap joint feature which enables rotational adjustments ensures correct positioning of bolt holes and thus simplifies the process.

Flexibility and Misalignment Compensation: The Lap Joint Flanges are very effective due to the fact that they increase the axial and the angular misalignments of the connected pipes. This same flexibility translates into vibration absorption, thermal expansion, and contraction allowing the system to put up with such incidences without stress

Versatility in Material Selection: Flanges which are in the shape of Lap can be obtained by making use of Stainless Steel, Carbon Steel, Alloy Steel, Low-Temperature Carbon Steel, High Yield Carbon Steel, High Nickel Alloy, Monel, Hastelloy, Nickel, Alloy 20, Inconel, and Titanium. It is because of this versatility agents shall be able to customize different operations required by different applications.

The implementations of the front joint flanges. Pipe flanges of lap-joint type are fitted into piping systems to link up pipes, valves and other equipments. They have two components: a reduced bend radius and a backing flange with few loose parts. Flexible backing flange is bolting to stub end while the pipes’ stub ends have end flanges welded, thus creating a pipe joint.

The accurate dimensions of the Lap Joint Flange will suit your piping systems as they will provide for a tight fit and a secure connection that is also performance oriented.

In order to fully ensure the quality and integrity of our Lap Joint Flanges Exporter, we set up rigorous tests as a process. In order to eliminate such occurrences, the discarded products should be serious tested such their durability, strength and performance. The platinex piping is indeed proud to be in the position of working for not only the national but also the global scale. Our guarantee to perfection and client satisfaction is the solid ground we stand on in the rare trade of industrial flange solutions worldwide.

lap joint flange

Lap joint flange are similar to other types of industrial flanges, but it does not have a raised face. Lap joint flanges are used in conjunction with a “Lap Joint Stub End”. The total initial cost of a lap joint flange along with a stub end is around one-third higher than that of comparable welding neck flanges. The pressure holding capacity of lap joint flanges is comparatively lower, and the fatigue life for the assembly is only one tenth that of welding neck flanges.

The lap joint flange with the stub end assembly is normally used in piping systems which require regular dismantling for inspection and cleaning. These flanges slip over the pipe, and are not welded or otherwise fastened to it. Bolting pressure is transmitted to the gasket by the pressure of the flange against the back of the pipe lap (Stub End).
