Advantages of LOKRING fittings

Advantages of LOKRING fittings

Streamlining the work schedule! Compared to welding, the work time has been reduced to one-tenth.

We would like to introduce the advantages of the "LOKRING fittings" that we handle. There is no need for maintenance or repairs, and since there is no heating work involved, the accident rate related to OSHA decreases. The quick and easy installation improves productivity. Additionally, the fittings that use mechanical tightening comply with the API 607 Fire Test, and they are products that do not require screws or ferrules, nor the use of wrenches. 【Advantages (partial)】 ■ Permanent connection ■ No heating work required ■ Safe prevention of construction errors ■ No need for purging or cleaning ■ Compliant with ANSI/ASME B31.1, B31.3, B31.4, B31.5, B31.8, B31.9 *For more details, please refer to the PDF materials or feel free to contact us.

Technology of elastic strain preload

Technology of elastic strain preload

A permanent seal is formed between metals! With elastic load applied, the durability of the connection is improved.

Introducing the technology of "Elastic Strain Preload (ESP)." During installation, the axial movement of the LOKRING driver on the joint body compresses the body against the pipe surface, initially compressing the pipe wall elastically, followed by plastic compression. As resistance to the compressive force on the pipe wall occurs, significant compressive loads develop at the contact points between the narrow sealing area within the joint body and the pipe surface. 【Features】 - The pipe wall is initially compressed elastically, followed by plastic compression. - Significant compressive loads occur at the contact points between the narrow sealing area and the pipe surface. - Plastic deformation occurs on the pipe surface beneath multiple sealing areas. - A permanent seal of metal is formed between the pipe and the joint body along a 360° circumference. - Durability of the connection is increased. *For more details, please refer to the PDF document or feel free to contact us.

No additional expenses for welding are required.

No additional expenses for welding are required.

Obtaining permits related to fire hazards, installing scaffolding and ventilation systems, etc.! There are various examples available.

If welding operations are eliminated, many indirect costs related to safety, labor, equipment, consumables, inspections, repairs, and monitoring will be unnecessary or significantly reduced. There are many examples, such as the installation of "sniff" areas, gas-free zones, rain shelters, fire monitoring systems, equipment, electrical cables, and purge lines. Additionally, ASME-certified welders will be freed from welding small-diameter pipes of 3 inches or less and can focus on welding larger diameter pipes or pressure vessels. 【Examples (partial)】 ■ Obtaining permits related to fire hazards ■ Installation of scaffolding and ventilation systems ■ Installation of "sniff" areas, gas-free zones, and rain shelters ■ Blank flanges/nozzles ■ Installation of fire monitoring systems ■ Installation of fire boxes/waterproof sheets *For more details, please refer to the PDF materials or feel free to contact us.
