Product advantages:
A common element shared by all standards is the need for a pipe manufacturer to demonstrate compliance with the standards’minimum performance requirements. In the case of GRP pipe, these minimum performance requirements fall into both short-term and long-term requirements. The most important of these and generally specified at the same level of performance in all the previously defined standards is joint, initial ring deflection, long-term ring bending, long-term pressure and strain corrosion capability. Lianzhong pipe has been rigorously tested to verify conformance to the ASTM D3262, ASTM D3517, AWWA C950 and DIN 16868 requirements.
Product application:
Water transport:For GRP pipes, its application in municipal water delivery engineering is particularly wide, because of its non-toxic, rust free, tasteless, no secondary pollution of water quality characteristics, making it very popular in the field of water delivery engineering.
Product performance test:Joint Testing:This important qualification test is conducted on joint prototypes for elastomeric gasket sealed bell and spigot joint. This is a severe test carried out in accordance with ASTM D4161. It incorporates some of the most stringent joint performance requirements in the piping industry for pipe of any material within the pressure and size ranges of Lianzhong pipe. ASTM D4161 requires these flexible joints to withstand hydrostatic testing in configurations that simulate very severe in-use conditions. Pressures used are twice those rated and 200 kPa (2 bar) is used for gravity flow pipe. Joint configurations include straight alignment, maximum angular rotation and differential shear loading. A partial vacuum test and some cyclical pressure tests are also included.

Product certification:
As shown in the figure below, our company has the relevant certification of ISO 14001:2015
