Product description
HDPE indoor water supply pipes are an excellent choice for household water supply. They are made of food-grade materials, which are hygienic and non-toxic, ensuring the safety of household water and making it safe for family members to drink directly. They have excellent flexibility and can effectively resist damage caused by temperature changes, external impacts, etc. For example, they can remain intact during cold snaps or when there is vibration from upstairs renovation. The inner walls of the pipes are smooth, which prevents scaling, ensures smooth water flow, makes water meter measurement accurate, and avoids water quality deterioration due to scale accumulation. They also have good corrosion resistance and a long service life, reducing the trouble and cost of pipe replacement.

Product Properties
1.Excellent chemical corrosion resistance: HDPE indoor water supply pipes can effectively resist the erosion of various chemical substances.
2.Meeting hygiene standards: The HDPE material itself is non - toxic and odorless, and does not breed bacteria or algae.
3.High strength and impact resistance: HDPE indoor water supply pipes have high strength and good impact resistance.
Application
PE indoor water supply pipes have advantages such as corrosion resistance and good flexibility, and are widely used in various scenarios. In residential buildings, they are used for the supply of cold and hot water in kitchens and bathrooms, ensuring water for daily washing and cooking. In commercial buildings, they provide stable water supply for places like offices and restaurants. In public buildings such as schools and hospitals, they can be used in the water supply and drainage systems of teaching buildings and wards to meet the water needs of a large number of people. They are also suitable for some small - scale indoor breeding sites, facilitating the transportation of water for breeding.

QA&QC
QA (Quality Assurance) focuses on preventing quality issues in PE water supply pipes through proper planning, process control, and staff training. QC (Quality Control) involves inspecting and testing pipes at various stages to ensure they meet standards. This comprehensive approach guarantees the high - quality and reliability of PE water supply pipes.
Packing,Storage,Handling and Transportation
Small - diameter pipes are packed in bundles, while large - diameter pipes are packed individually. Wrap them tightly with soft materials, especially protect the cut ends of the pipes to prevent scratches. Clearly mark the specifications, models, batch numbers, manufacturers and other information on the outer packaging.
Store the finished products in a cool, dry and well - ventilated warehouse or site. It is strictly prohibited to expose the pipes to the sun (to prevent UV aging), place them close to heat sources and chemicals, or stack them outdoors (to prevent sun exposure and rain). The stacking area should be flat. Stack pipes of different specifications separately with a moderate height to prevent deformation caused by long - term heavy pressure.
During the transfer process, handle the pipes with care! Throwing, dragging and violent impacts are strictly prohibited. Manually carry small - diameter pipes, and use flexible slings with forklifts or cranes to smoothly lift large - diameter pipes.
During transportation, select appropriate vehicles and load the pipes stably. Effectively separate the pipes from each other and from the vehicle compartment with soft cushions (such as wooden wedges and rubber pads) and tie them firmly to prevent scratches, indentations and deformation on the pipe walls caused by displacement, rolling friction or collisions due to bumps during transportation. Drive steadily and avoid sudden braking.
