Flexible corrugated stainless steel pipe 20 мм (3/4")

A feature of corrugated stainless steel pipes is the highest environmental friendliness, colossal reliability, and an attractive appearance. The estimated service life of corrugated stainless pipes and stainless fittings is over 100 years.
Flexible stainless steel pipes 20mm are based on flexible corrugated thin-walled stainless steel pipe and brass connectors (fittings.
The pipeline is designed:
working pressure up to 15 kg / cm2, maximum up to 60 kg / cm2
operating temperature up to + 100 ° C, maximum from -40 to + 150 ° C.
Bore: 12mm, 15mm, 18mm, 20mm, 25mm, 32mm.
Minimum inner diameter: 14.4mm 21.0mm 27.0mm 34.0mm.
Maximum outside diameter: 18.1mm 25.0mm 31.6mm 37.0mm.
Recommended bending radius: 50mm 80mm 110mm 140mm.

Metal corrugation for heating price per meter - high reliability of the system, its durability, low cost of installation materials. Installation of pipes takes not minutes, but seconds, and does not require special tools, equipment and skills in work. After installation and testing of this pipeline, no additional “pull-ups” of the “pipe-fitting” connections are required, but the principle of “make and forget” applies. flexible metal stainless steel hose for hot water, stainless steel pipe for boiler.

  Corrugated stainless pipe Kofulso or corrugated pipes of Russian production

In contrast to thick-walled steel pipes, corrugated stainless steel pipe has a number of advantages that are important when carrying out internal systems.

All corrugated stainless steel pipes are produced using the same technology, the stainless strip can be welded in three types: tig-welding, microplasma and laser welding.

Corrugated stainless pipe has such a feature as resistance to any mechanical stress: external and internal. Compared to plastic, this product is not afraid of repeated freezing. The environmental safety of corrugated pipelines is an advantage as it is made of food grade polished stainless steel tape AISI 304.

Ease of use is one of the factors influencing the choice of our customers when installing a pipeline system.

Flexible corrugated stainless steel pipe is easy to connect with couplings.

To connect corrugated pipes, special brass fittings are used, which have silicone seals and retaining rings in their design. Coupling devices ensure reliability and tightness of the connection. The service life of the coupling system allows the flexible stainless steel piping to be positioned in hard-to-reach places. I did it well and forgot.

The indisputable advantages of flexible corrugated pipelines make it popular in all countries of the world. It is not only reliable and durable, but also environmentally friendly and safe. The prices for corrugated stainless pipes of our own production are based on quality and capabilities and allow the use of these materials in many areas of activity.
