Stainless steel DIN collar flanges
The range of shut-off valves from our company includes a collar flange, which has a wide range of applications. The flange is used to connect pipes. And it can also serve as connecting elements in the designs of various devices. The diameter of the products makes it possible to successfully use collar flanges in large diameter pipes, which are characterized by labor-intensive installation. Stainless steel products are convenient and easy to operate, they reliably and hermetically connect the pipeline elements, withstand high pressure in the connection area.
The use of collar-type flanges has a number of advantages:
With such fittings, it is possible to dismantle a part of the pipe without cutting it, this makes it easier and faster to repair the pipeline.• The joints are characterized by strength and tightness.
• Stainless products have a long service life. They are resistant to the effects of liquid and gas flows, are resistant to corrosion.
Functionalstainless steel flangescan be installed in pipelines that run in regions with harsh climatic conditions. The metal perfectly withstands low temperatures, exposure to humid air.
• The long service life of pipeline parts makes it possible to rarely repair and replace elements.
ALFA-STAR offers collar flanges of different diameters and weights, which allows customers to choose the best option for a specific application. All products meet GOST standards and have guaranteed quality, affordable price.
