Capillary Tubes act as a connecting medium between the condensers and the evaporators. Due to its long length and well-defined circumference, it effectively controls the flow of refrigerants

Capillary Tubes are helpful in domestic and commercial applications that experience constant heat loads on their evaporators. These tubes are in demand in precise apparatus and instruments, electrical appliances, oil & gas plants, and other industries.

 Their sizes range between 0.30 mm to 8.00 mm and can adequately fit in standard or heavy walls. 

Mangalam Metal Corporation is one of the renowned suppliers and exporters of Capillary Tubes and Pipes in India. Depending on the industry and its usage, we offer tubes and pipes available in different attributes like size, lengths, materials, etc.


While choosing a tubing material, one must also consider two primary factors: 

  • Chemical Compatibility of the Sample

During chemical testing, there are high chances that some samples might stick to the surface of the tube, causing low yield or sample loss. Thus, one must select the best-in-class material for the compatibility of the sample. 

  • Mobile Phase

Usually, tubing selected for the chemical compatibility causes problems in separations and sampling. The inner diameter of the tubing must be free of impurities (such as oil, grease, or other foreign materials) for the fluid to flow through the chromatography system at a stationary phase. 

It is significant to choose the accurate capillary tubes for the better performance of the HPLC equipment, especially at high-speed and non-ambient pressure.

Following are some industries and their applications where you will find our Capillary Tubes installed.

  • Dust Collector
  • Refrigerant Condensers
  • Air Coolers
  • Regenerative Air Heaters
  • Air Conditioners and Refrigerators
  • Fire Protection System
  • Chromatography
  • Distant Reading
  • Gauges
  • Diaphragm Seals
  • Transmitters
  • Chromatography








Inconel, Monel, Hastelloy, Copper, Brass, Nickel, Copper-nickel alloys, Copper alloys, nickel alloys, duplex stainless steel and other types of steels.




  • The Smoothness of the Inner Diameter – The inner diameter of the capillary tubes should be smooth and precisely cut. It ensures the hassle-free flow of fluids and improves system resolutions.
  • The Concentricity – One must ensure the outer diameters of a capillary tube should have a common center. It assures to reduce the flow disturbances at the connection points and avoids the chances of leaking.
  • Volume Stability – Depending upon the appliance and flowing fluid, one should select the material and length of the capillary tube. A more controlled volume will ensure to reduce dwell time and lessen diffusion effects. 
  • Type of Flowing Fluids – In industrial applications, basically, two types of fluids are found: liquid and gases. These fluids might be flammable, toxic, or volatile components. Thus, one should have to keep in mind the type of fluid they use in the applications before the installation process.
Markings and Packing

Product packaging serves to protect the products inside. Mangalam Metal Corporation effectively ensures all the products are deliverable to our clients securely. In the case of exports, we follow all international standard protocols of packaging.

Often, we export them in wooden cases. We mark our products with Grades, Lot Numbers, Size, Degree, and our Trademark. We also make custom markings on the products as per the requirements of our clients.

Quality Assurance

At Mangalam Metal Corporation, all products are subject to strict supervision at each production chain, right from purchasing the raw materials to dispatching products. All the processes undergo inspections for conformity to ASTM, ASME, MSS, and JIS codes and standards.
