Technical Data :

Mexflow meets the mandatory inspection requirements:

• Chemical composition -Phosphorous = minimum 0.015%. max 0.040%
• Carbon Content Test -Window based software determines the content of carbon on the inner surface of copper tubes and fittings using combustion method,
• Tensile strength -Mexflow pipes have been tested to the best of its tensile strength keeping in mind all the testing norms in the industry.
• Non Destructive test -Each tube is subjected to an Eddy current test for detection of local defects. We are the only manufacturer of this category (Medical) of tubes
• Mexflow Copper Tubes -Compatible for CFC-Free Refrigerant for VRV, VRF, RACs, Visicooter, Refrigerator and Other ACR Applications, The use of copper in air-conditioning and refrigeration systems has grown steadily in recent years. MEXFLOW tubes increases the efficiency of the system and substantially reduces the emission of harmful gases and SPMs. MEXFLOW copper tubes are designed for longer service life. Mexflow Copper Pipes Are Also Available With Mexflow Copper Fittings For The Complete ACR Applications. Other Applications of MEXFLOW Copper Pipes: Medigas Pipeline Plumbing LPG/CNG Gas Pipeline I City Gas Distribution.

Copper Tubes :

• 3/16 Dia to 6 Dia
• Copper Fin Tubes
• Copper Fittings - 1/4 Dia to 5 Dia
• Only manufacturer in India having In-House Carbon Content Test facility as per EN 723

Applicable Standard :

Copper Tubes :

• BS 2871 Part I - Copper Tubes for water, gas & sanitation
• iBS EN 1057 -Seamless, round copper tubes for water and gas in sanitary and heating applications
• iASTM B 88 - Seamless Copper Water tube

Requirements as per EN 1057 :

• Chemical Composition -Copper Tubes ore designated under alloy C 106 also called DHP (Deoxidised High Residual Phosphorized Grade). The requirement is as follows : Min. Copper including Silver % – 99.9%
• Dimensional Tolerances-Dimensional tolerance to confirm to the EN 1057. It must be noted that the dimensional tolerance on copper tubes as specified for the outside diameter is very important so that the annual gap between the tube & the fitting is within a designated dimensional tolerance to ensure correct & proper capillary action during the process of soldering or brazing. Please refer to Table 1, 2 & 3 for dimensional tolerance on outside diameter, dimensional tolerance for wall thickness is given below:
• Freedom from Defects Surface Quality -The outer diameter & inner surface of the tube shall be clean & smooth. An attack on copper tube can occur causing pitting corrosion when a thin film of carbon is formed within the bore of the tube during the manufacturing process. Concern over deleterious film in the bore has prompted the newly adopted EN 1057 to call for a carbon film & carbon content test, concerning the measurement of the residual & potential carbon in a copper tube bore. MEXFLOW Copper Tubes meet this criteria.
• Freedom from Defects Tests - Each lube shall be subjected to one of the following test: Eddy current test for detection of local defects, in accordance with pr EN1971. Or Hydrostatic test or Pneumatic test. The choice of the method selected from the above, is at the discretion of the manufacturer.
• Bending - Hall hard copper tubes and soft annealed copper tubes must undergo a bending test without formation of wrinkles on the inner bend. Bending is an expansion of the outside surface of the bent tube & a contraction of the inner surface of the tube. The formation of wrinkles on the inner surface shows either the fact that the physical properties of the tube are not in order or the bending mechanism i.e. the bending tool has got a gap more than the diameter of the tube, which allows the tube to get raised while conducting the bending operation from the former, allowing wrinkle formation to take place on the inner surface.

Indigo tubes are 100% carbon free. All tubes are cleaned and the sample tested to meet the residual requirements as specified by the codes at 0.038g/m2 (0.35g/ft2). Coils are normally furnished in ‘O60’ temper and straight lengths in H58 temper. 100% RoHS Compliance.
