. Overall Responsability For Quality

We manufacture our product components and monitor each production stage in compliance with the Best Practice models and ISO 9001:2008 requirements by respecting the principles of a “green” production and by adopting control standards up to our product criticality.

 
     
 

WE PROTECT THE HOSE LINER WITH A CAREFULLY MADE STAINLESS STEEL BRAID TO PRESERVE ITS PURITY

 
     
 

. Braiding Department

 
 
         
 

. Top quality materials

MRG flexible hoses are produced with different liners: EPDM, SILICON, PEX (tradename MRG EPX), THERMOPLASTIC SILICON (tradename SILTER) rigorously certified for sanitary application or specific installations in the food industry and HVAC sector. The external coating is made of stainless steel AISI 304, AISI 316 or nylon. The components are machined from CW 614N/ CW 617N/ CW510L with or without protective surface treatments (stainless steel fittings are available upon request).

   
     
 

HANDLED WITH CARE

 
     
 

. Headquartes and Production

 
 
         
   

. Technical insight

Strict laboratory tests performed during the design stage and checks on the finished product prove the reliability of our products which is further validated through continuous studies on new materials and technologies.
All flexible hoses are guaranteed in conformity with the European regolation.

 
     
 

POSITIVE PROSPECTS

 
     
 

. Innovation and Quality

 
 
 
         
 

. Performance

Detail of some technical analysis, periodically carried out in compliance with the Approvals’ requirements (pressure test, water-hammer, burst, pull test, static and dynamic test).

   
         
   

. Brust Test

Consists in a steady pressure increase till hose burst in accordance with the test parameters of the International Regulations to ensure the water tightness.

• Water temperature inside the hose 90°C
• Test chamber temperature 90°C
• Initial operating pressure 15 bar

 
         
 

. Water Hammer Test / Colpo d’Ariete

This important test simulates the solicitations the hose will undergo in its lifetime applying variable impulses from 5 to 50 bar with numerous pressure variations reproducing the turning on/turning off of the faucet.

The hose withstands 30 impulses per minute after a series of 1000 solicitations with water flow at 90°C.

   
         
   

. Pull Test

This test enables to verify the correct crimping and tightness of both hose fittings.

The company peculiarity is represented by the accurate control of raw materials and the close supervision of the entire manufacturing process to guarantee reliability in the long term.
