Types of Jis Lap Joint Flanges
The Jis 5k Lap Joint Flanges are often used in low
Pressure systems. For example, in some auxiliary water systems in a power plant where the pressure is relatively low, these flanges can provide a cost - effective solution.
The Jis 10k Lap Joint Flanges are a middle
Ground option. They can handle moderate pressures and are commonly used in many steam and water pipelines within the power plant.
The Jis 20k Lap Joint Flanges are designed for high
Pressure applications. In the main steam lines where the pressure is extremely high, these flanges ensure a secure and leak - free connection.

The manufacturing of Jis Lap Joint Flanges begins with the selection of premium materials, often stainless steel, to ensure durability and resistance to corrosion. The process involves forging, where raw materials are heated and shaped under high pressure to create robust components. For our Forged DN4000 Lap Flange, precision is paramount; each piece undergoes rigorous quality control to meet industry standards.
Once forged, the flanges are subjected to machining processes to achieve the desired dimensions and surface finishes. This includes the creation of the end lap joint, which allows for easy alignment and assembly with pipes. The final step involves thorough inspection and testing to ensure that each Lap Joint Stub and Lap Joint Loose Flange meets our stringent quality criteria.
Application of Jis Lap Joint Flanges
Chemical Processing Plants
In chemical processing plants, lap-joint flanges are commonly deployed for systems that involve corrosive liquids. Because they can have different materials for the stub end and backing flange, these components can be used with a wide range of chemicals under various conditions.
Oil and Gas Industry
Lap joint flanges are applicable in pipeline and equipment for oil and gas industry hence need regular inspection and maintenance.
Petrochemical Refineries
Petrochemical refineries often use lap joint flanges to link piping systems, reactors, vessels etc. Due to its inherent flexibility towards thermal expansion/contraction on the other hand requires less effort while assembling or disassembling it thus making the turn around time during shutdowns for maintenance shorter.
Water Treatment Plants
Water treatment facilities rely on lap joint flanges to join pipes carrying potable water, wastewater and chemicals which are used for purification purposes.
Food and Beverage Industry
The food processing factories fitted lap-joint flanges on their piping systems. They are best suited for environments where cleanliness is key due to their cleanable hygienic design; ease of maintenance; ability to undergo thermal expansion without damage.
