Fittings for Stainless Steel Pipes（Connection Type - Unequal Diameter Tube：Union Straight）

Stainless steel pipe fittings are parts for connecting stainless steel pipes and connecting to equipment. Stainless steel is characterized by its excellent corrosion resistance and is widely used in general buildings, food equipment and chemical equipment. There are several types of connection methods for fittings for stainless steel pipes. The compression type is a method in which a sleeve is crimped on a pipe and connected, and is also suitable for connecting different kinds of pipes such as a combination of stainless steel pipes and copper pipes. The double ferrule method requires less torque for tightening and does not require special tools. It may be easy to remove and reuse the fittings. Since it is compatible with water and air, as well as chemicals and oil, it is used in scientific equipment and semiconductor manufacturing equipment. The elmet type has a structure in which the edge of the sleeve bites into the piping and can seal high-pressure fluid. Piping is possible simply by cutting the pipe and tightening it with a nut, thus reducing the number of work steps.

Mechanical Fitting Socket for Stainless Steel Pipes

HITACHI KINZOKU

Mechanical type tube fitting developed for stainless steel pipes. A highly reliable fitting with superb corrosion resistance and heat resistance, which optimizes the special characteristics of lightweight and strong stainless steel piping.

[Features]
· Zlok® is a mechanical pipe fitting that has been developed for stainless steel piping.
· Highly reliable fitting benefits from the light and strong characteristics of stainless steel pipes, and has superior corrosion and heat resistance properties.
· The packing has stable long-term sealing properties due to a structure with appropriate pressure applied to the surface.
· A fluorine rubber material with superior durability, heat resistance, and resistance against aqueous chlorine that satisfies leaching standards when used as a water supply device is used in the packing.
· Because the connector between the pipe and the fitting has a tapered surface and is tightened using a nut, a strong connecting force is achieved by the so-called wedge effect.
· The packing does not have to be removed from the fitting while laying pipe.
· Furthermore, because piping cannot be done unless pipe ends are expanded, pipes do not fall out.
· Loose pipes can be found easily using a unique indicator that distinguishes between hand tightened and fully tightened pipes.
· When final tightening is forgotten, water will leak from fittings during water pressure tests, thus allowing loose pipes to be detected.
· Expanded pipes can be corrected easily using an automatic machine after pipe setting.
· The pipe can easily be held and secured because the connector between the pipe and the fitting is not prone to wobbling.

KOMA SUS FIT, Reducing Socket RS

RIKEN

Pipe-expanding mechanical fitting uses a dedicated pipe expander for high load bearing capacity.

[Features]
· Strong fitting with pipe expansion method: Because the structure of the fitting includes nuts attached to the expanded part of the pipe, it demonstrates a strong pull off prevention force. If nut is not tightened, there is no need to worry about the nut coming off if it is engaged with the screw on the main body.
Easy pipe expansion: With the dedicated pipe expander, pipe expansion work can be easily performed.
· Fast and reliable construction: Post pipe expansion fitting can be easily performed with a pipe wrench. No need to remove any parts other than nuts during fitting. By providing a packing room, packing falls are prevented. This prevents errors such as non-mounting of parts during construction.
· Tightening omission can be confirmed at a glance with FP colors of red and blue: Even with fitting completed by hand tightening, leakage can be detected in the water leakage test, and problem locations can be confirmed quickly. In hand tightened (non-tightening) state, red FP color can be visually checked, and once the fitting is tightened at an appropriate torque, the red FP color is hidden under the blue FP color and can no longer be seen. In this manner, tightening completion can be checked at a glance.
