Loyalty brand strictly implements GB/ t13663-2000 "polyethylene (PE) pipe for water supply", referring to iso4427-1996. The health indicators are in line with GB/ t17219-1998 safety evaluation standards for equipment and protective materials for the delivery and distribution of drinking water and hygienic standards for drinking water. The color of PE pipes for water supply is blue or black. There should be a co-extruded blue color bar on the black pipe, and there should be at least three color bars along the longitudinal direction of the pipe. The outer surface is clean and smooth, free of air bubbles, obvious scratches, dents, impurities and uneven color defects. Pipe ends should be cut flat and perpendicular to the pipe axis. The length of straight pipe is generally 6m, 9m, 12m, and can be supplied as required by customers. Diameter of less than 63 mm Φ pipe can coil, length of 100 meters, 150 meters, 200, meters, can also according to customer's requirements.
1. Corrosion resistance: polyethylene is an inert material, which can resist the erosion of various chemical media. No electrochemical corrosion is required.
2. Non-toxic :PE water pipes are not suitable for heavy metals to add jing, do not deposit dirt, and do not breed bacteria. The sanitary performance of pipes conforms to GB/T 17219.
3. Good water permeability: the inner wall is smooth, the friction coefficient is extremely low, and the medium passing ability is high.
4. No leakage: the PE water supply pipe mainly USES fusion connection (hot or electric fusion connection) and socket connection. Compared with rubber ring type joint or other mechanical joint, there is no risk of leakage caused by the distortion of fixed joint.
5. High toughness :PE feed pipe is a kind of high-toughness pipe, its breaking elongation is generally more than 500%, and it has strong adaptability to uneven settlement of pipe base. It is also a kind of pipeline with good anti-seismic performance.
6. Excellent flexibility: the flexibility of polyethylene enables PE feed pipes to be coiled. For non - groove construction, PE water supply pipeline trend is easy to change in accordance with the requirements of construction methods.
7. Good anti-scratch ability: it can effectively avoid the material stress concentration caused by scratch in the water supply pipeline system, thus causing the occurrence of pipeline damage accidents.
8. Good impact resistance :PE pipe has good toughness, high impact strength, and heavy objects directly press the pipe without causing pipe rupture.
9. Good construction performance :PE pipe is light in quality, simple in welding process, convenient in construction and low in construction cost.
10. Long service life: PE pipes can be used safely for more than 50 years under rated temperature and pressure conditions
Tubing and fittings shall have the product quality inspection report of the quality inspection department and the qualification certificate of the production plant.
When the pipes are stored, transported and transported, the pipes shall be tied with non-metal rope, and the ends of the pipes shall be sealed off.
Pipe material and fittings shall not be thrown and cracked during storage, transportation and transportation.
During storage, transportation and transportation of pipe and fittings, it shall not be exposed to sun and rain; Do not contact with oil, acid, salty and other chemicals.
The storage period of the pipe and fittings from production to use should not exceed one year.
Acceptance inspection must be carried out for receiving pipes and fittings. First acceptance of the product operating instructions, product quality certificate, quality assurance and various performance inspection and acceptance reports and other related materials.
When evaluating pipe and pipe fittings, you should sample in the same batch, and check the specification, size and appearance performance according to the current national standard "water supply (PE) polyethylene material", and conduct a comprehensive test when necessary.
