Fittings for Stainless Steel Pipes（Connection Type - Equal 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 Metals

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.
