We are?pleased to announce that Rifeng PP-R monolayer pipe and fiber composite pipe have achieved NSF-61 certificate.

?

NSF-61 is?an internationally recognized standard for “Drinking Water System Components-Health Effects”, concerning stringent requirements on materials and products used in contact with drinking water. It is developed by the National Sanitation Foundation (NSF), a global independent public health and environmental organization, and the American National Standards Institute (ANSI) which oversees the consensus for developing standards for manufacturing and procedures in the United States.

?

Rifeng uses?high quality imported raw materials and manufactures PP-R pipes based on lean production management, providing significant product advantages including, but not limited to,?excellent product consistency, high temperature resistance, low incidence on taste and odor and good impact strength. Therefore, Rifeng’s PP-R pipes are suitable?for potable water piping system with hygienic and non-toxic features. As tested and authorized by NSF, these Rifeng products are specifically formulated for drinking water system components with NSF-61?compliance. This NSF-61 certification provides the highest level of assurance that our products are safe for use in drinking water service.

?

Apart from NSF-61, Rifeng PP-R systems have also been certified?by DVGW, which provides technical and scientific support for the gas and water industries, focusing on safety, hygiene and environmental protection. DVGW is the most stringent testing association for water and gas worldwide and has been in business for over 200 years.

?

Through our manufacturing processes and our stringent testing, we are proud?that our Rifeng PP-R systems have been?marked with the DVGW certificate. The DVGW quality mark indicates that Rifeng PP-R Systems obtained the highest level of safety and quality in provision of natural gas and potable water to the public.

?

Since 2008 when Rifeng?first?launched PP-R systems, PP-R systems have been continually upgraded to the highest?standards. With an annual output of over 550 million meters in PP-R pipes and over 600 million sets in PP-R fittings, production capacity of Rifeng can be considered as one of the best in the country and the world. At the same time, we are?very proud to say that Rifeng is the only enterprise in the national piping industry that has achieved both NSF-61 and DVGW certifications. Every one of these achievements is?further?proof of Rifeng's quality and strength.

Obtaining NSF-61 and DVGW demonstrates our continued commitment to work on product management and development. It also explains that Rifeng is committed?to improve quality management systems?to achieve the highest standards in various areas. However, the process?does not end there. Rifeng continues?to improve overall performances on technology, development, processes and procedures?to?offer high-quality and consistent products that meet?and exceed?customer needs and expectations.
