CK Pre-Seal 20K Fitting

CK Pre-Seal 20K Fitting

From now on, applying sealant will no longer be necessary!

In the construction of piping where water tightness and air tightness are required, the task of applying sealing material to the threads has been an important yet cumbersome job to maintain the quality of the piping over the long term. The "CK Pre-Seal 20K fittings" come pre-coated with fluorine-based sealing material for all types of 20K fire protection piping fittings, eliminating the need for any tedious work. It completely removes the cumbersome application process that previously relied on the experience of the workers, resulting in a speedy and reliable connection.

Situations and places suitable for LOKRING fittings.

Situations and places suitable for LOKRING fittings.

Small-scale/large-scale projects, etc.! Suitable for situations that require work under any weather or conditions.

We will introduce the situations and locations where our "LOKRING fittings" are suitable. They are ideal for places with limited space, underwater, or in situations involving flammable or explosive hazards, as well as when there are losses or issues due to plant downtime. They are also suitable for any weather or conditions that require work. Additionally, ASME-certified welders are freed from welding small-diameter pipes of 3 inches or less, allowing them to focus on welding larger pipes or pressure vessels. 【Suitable situations/locations (partial)】 ■ Places with limited space ■ Underwater ■ In situations involving flammable or explosive hazards ■ When there are losses/issues due to plant downtime ■ When work is required in medical gas systems *For more details, please refer to the PDF materials or feel free to contact us.

CK joint

CK joint

The inner box has handles for easy removal! Introducing screw-in ductile cast iron pipe fittings.

The "CK Joint" is a correct joint according to JIS standards. In the manufacturing process of the joint, we use automatic molding machines such as Disamatic, FCMX-I, and AMFIII, which have precision comparable to that of precision machining equipment, and the cores are automatically set, resulting in very high dimensional accuracy and precision. The material is black heart ductile cast iron, which has about twice the strength of gray cast iron and is as tough as cast steel. Additionally, it possesses excellent ductility, which gray cast iron completely lacks, providing strong and stable quality with superior impact resistance, vibration absorption, and machinability. 【Features】 ■ Correct joint according to JIS standards ■ Uses Disamatic, FCMX-I, and AMFIII automatic molding machines ■ Cores are automatically set, resulting in very high dimensional accuracy and precision ■ Material is black heart ductile cast iron with about twice the strength of gray cast iron ■ Strong and stable quality with excellent impact resistance, vibration absorption, and machinability *For more details, please refer to the PDF document or feel free to contact us.

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.
