Cross-linked PE Hot and Cold Water Plumbing Pipes with Expansion Ring Technology

Astral PEX-a PRO is a revolutionary flexible piping system that stands apart as a global leader in hot and cold water plumbing applications. Our PEX-a pipes are a marvel of modern engineering, renowned for excellent flexibility and longevity. The combination of cross-linked polyethylene plumbing pipes and expansion ring technology offers numerous advantages, including improved water flow, secure connections, and user-friendly installation.

Our PE plumbing pipes can join with brass or polyphenylsulfone (PPSU) fittings seamlessly by harnessing the inherent shrink-back property. This innovative technology eliminates the need for ‘O’ rings, guaranteeing an absolute watertight joint with enhanced water flow. Astral Pipes uses an infrared ray oven process to ensure exceptional quality and strength, which results in a system that surpasses conventional plumbing in every way.

Our versatile flexible piping system provides diverse installation options, such as a single connection, tee connection, pipe-in-pipe installation, and ceiling installation. It provides a conduit for superior water flow compared to alternative plumbing pipes and fittings. Astral PEX-a PRO hot and cold water plumbing system offers a comprehensive range of tools and accessories for safe and efficient installation.

  • Supporting Fixtures:ย Astral PEX-a Pro flexible piping requires proper support to ensure a leak-proof water plumbing system. Horizontal and vertical runs should be cradled by pipe clamps or hangers, strategically positioned near the riser on the horizontal connections. Avoid rough or sharp edges on hangers to avoid damage to your PEX-a pipes.
  • Pressure Test:ย Building codes require pressure testing water or plumbing pipelines before covering them. Due to the memory of PEX-a PRO plumbing pipes, contraction increases over time after expansion. To ensure accurate testing, allow a minimum waiting period before applying pressure.

Under normal conditions, Astral PEX-a PRO flexible piping joints can be tested 30 minutes after assembly. However, in extreme winter weather, the waiting time must be longer.

  • Heat Loss:ย Heat loss in crosslinked polyethylene PEX-a pipes depends on factors like pipe size, material, installation type, insulation, and temperature difference. When buried, the enclosure’s materials also impact heat loss. The following graph illustrates the heat losses for crosslinked polyethylene pipes under varying conditions.
  • Thermal Expansion:ย As desired with hot and cold water plumbing pipes, PEX-a pipes expand with heat and contract with cold. While expansion is a factor, practical issues are minimised due to the material’s properties. Astral PEX-a PRO plumbing pipes experience lower stress levels than metal or other plumbing pipes under similar temperature changes. This results in smaller loop requirements compared to copper systems. Expansion is a primary concern in hot water flexible piping lines and can often be accommodated by strategic plumbing pipe direction changes.
    • Long straight PEX-a pipe runs require expansion loops or offsets to accommodate thermal movement
    • One properly sized loop is sufficient per straight run, regardless of length
    • Multiple smaller loops can be used instead of one large loop
    • Use smooth straps to hang the PEX-a pipe and prevent movement restriction

Tables provide estimated loop lengths based on the plumbing pipe size, run length, and temperature. Use them as a quick guide for determining acceptable loop lengths for the plumbing pipe.

How to Join?

Cut the Pipe

Make a perpendicular cut on the PEX-a pipe with a sharp plumbing pipe cutter. It helps to clean grease and pipe chips from the plumbing pipe end. Fit the plastic ring on the pipe and make sure the pipe is flushed with the upper edge of the ring.

Place the Ring Over the Pipe

Insert the pipe into the ring until the pipe reaches the safety stop which exists inside the ring.

Expand the Pipe

Attach the correct size expander to your battery tool. Insert the expansion head into the plumbing pipe and start trigger. Continue expanding until the tubing and ring shoulder meet on an expander head that follows the recommended expansion count. The head may rotate automatically to ensure even expansion. Making expansion are slightly different when using a tool that features auto rotation.

Insert Fitting Body

Release the plumbing pipe from the expander and insert the fitting immediately into the PEX-a pipe end. Press the fitting firmly for a few seconds until the PEX-a pipe shrinks to ensure that the plastic ring makes firm contact with the end of the fitting.
