Domestic Running Water System

一、Drinking water pipeline status
①Pollution of pipe corrosion,scale to water quality
②Pollution of transudation in anticorrosive lining to water quality
③Pollution of microbial reproduction to water quality
④Pollution of residual chlorine disinfection by-product to water quality
⑤External pollution caused by omission of pipe network system
⑥The enforcement of regulations on the sanitation management and supervision of drinking water is insufficient,the mechanism is unreasonable,poor management etc cause water pollution

二、National Policy

 1、The State Council issues policies
●<Opinions on Strengthening Urban Infrastructure>issued by the State Council in Sept 6th 2013.
◇Premier Li Keqiang emphasized that accelerating the upgrading and construction of urban water supply facilities is first goal and we would actively promote the urban and rural development with regional water supply,as well as strive to achieve a national urban penetration rate of 95%,and water quality standards by 2015
●In 2015,the State Council officially issued the “ Ten Water Rules”with some especial emphasis
◇Define standard time of drinking water,major rectification measures,testing method and the site as well as responsibility subjects
◇By 2020,over 93% of cities at or above the third level in centralized drinking water quality 
◇Around 2030,over 95% of cities at or above the third level in centralized drinking water quality 


2、Central Ministries and Commissions issue policies
●In January 2007, Ministry of Health issued a new standard for drinking water GB5749-2006 <Sanitary Standard for Daily Drinking Water >,which increased the water quality monitoring indexes of residential drinking water from 35 items to 106 items,and required the water quality monitoring sampling point to be extended to the end of the official website
●On January 2,2013,Ministry of Housing and Urban-Rural Development issued that <National Civil Building Engineering Design Technical Measures> and GB50015< Technical Specification of Building Water Supply and drainage> and emphasized that water supply should use stainless steel pipe.
●On February 17,2015, Housing and Urban-Rural Development , NDRC, Ministry of Public Security ,Commission of Health and Family Planning jointly issued <Notice of Strengthening Urban Secondary Water Supply Facilities Construction and Management to Ensure the Water Quality and Safety> , it will ensure the safety of secondary water supply raised to national counter-terrorism strategy standard.What’s more ,it clears that the pipeline,pools and equipment from household water meters(including water meters) to municipal water supply facilities shall be operated and maintained by the owner of the unit designated by the local people’s government,actively encouraged water supply enterprises to gradually extend the management of water supply facilities to residential water meters
●On May 15 2017,Ministry of Housing and Urban-Rural Development issued <Technical Regulations on Direct Drinking Water for Construction and Residential Areas>,which clearly pointed out the pipes for direct drinking water system should be made of stainless steel pipes that meet the requirements of food grade.
●According to the<GB/T50378-2019 Green Building Evaluation Standard> implemented by the ministry of Housing and Urban-Rural Development pointed out that stainless steel pipes and pipe fittings are required for indoor water supply pipeline
●GB50015-2019<Design Standards for Building Drainage> pointed out that indoor water supply pipes should be corrosion-resistant and installed with convenient and reliable stainless steel pipes


3、Local governments issue policies
●Fujian ,Changsha ,Shenzhen ,Nantong and other places have issued relevant legal documents,formulated the technical specifications of secondary water supply pipeline system,and clearly stipulated stainless steel pipeline should be used into the secondary water supply into the household pipeline.

三、Application Scenarios

Home decoration


四、Selections of Connection Method
Double Press Fittings


When home decorates,chooses the double press fitting of stainless steel pipes and pipe fittings to form a loop connections and cascade connection ,promoting water in the whole pipeline system to carry on the circulation exchange by any point,forms a running water pipe network 
①Health and environmental protection of stainless steel pipes
②The thermal insulation performance of stainless steel pipe is 24 times than copper pipe,reducing the heat loss,especially suitable for hot water transportation
③The running water pipe reduces the breeding of microorganisms and ensures the health and safety of drinking water
④Stainless steel material is safe and non-toxic,no corrosion and exudation,no peculiar smell or turbidity problem,won’t cause secondary pollution to water quality ,keeping water quality pure and sanitary,fully guarantee the safety.
⑤Beautiful appearance,clean,fashionable conduce to raise city building level , can be bright outfitted and dark outfitted
