PEX Composite Pipes

Sagar Strong'N'Safe Composite Pipes has been selected to meet compressive and flexural strength requirements. This helps to combine the advantages of metal and plastic pipes and eliminate the disadvantages of both materials at the same time. The aluminium core is absolutely diffusion tight and reliably prevents oxygen or gases from permeating into the pipe. It compensates and reduces snap-back forces and heat expansion with changes in temperature.

Applications:

As a key type of Building Material, it is widely used in the following fields:

  • Polygon PEX under-floor heating system.
  • Polygon PEX Plumbing system.
  • Easy installation and sufficient accessories
    The PEX pipe acquires easy installation and sufficient accessories due to the flexibility, less but special pipe fittings. Even without tap threading, die threading or welding, it can be matched with the standard pipe fitting.
  • Advanced technology and imported materials
    With advanced equipment from NOKIA-MAILLEFER and international patent USP4117195, one-step Monosil PEX producing technology, we used imported materials which are compliant to the GB!T18992.2 standard to ensure the high performance of the pipe. Steam-pressure cross-linking technology is used to reduce the longitudinal shrinkage.
  • Satisfying customers' requests
    According to the customers' requests, we offer oxygen-leaking resistant layer and anti-UV composite PE-Xb pipe. We also promise fast production of 20m/min (ON 20mm pipe), quick delivery and production with customized size.

Benefits:

Pre-COS

Our product made from PVC, CPVC, PE & PPR raw materials which differ as follows from many of the pipes, hoses and fittings commercially available.

  • Higher mechanical stability.
  • Improved chemical stability.
  • Higher softening points.
  • Greater residual strength at high temperatures.
  • Higher compression strength.
  • Greater safety due to material stability.
  • Environment stress crack, corrosion, frost, kink & rot resistant.
Interior smoothness

Our product has outstanding interior smoothness and is thus optimized for flow. They have following advantages:

  • Very high delivery rate.
  • Low pressure loss.
  • Reduction of blower power requirements.
  • Lower operating costs.
Crush-Proof

Our pipes & hoses with this symbol are specially designed for workshop use and laying on the floors. They are able to resist crushing to some extent of entirely when driven over or stepped on. Please refer to the relevant product description for more details.

Hygienic

The pipes & fittings being free from corrosion & negative biological effect, taste & odor nature, it does not change the water quality.

industrial

Our pipes, hoses & fittings are specially design for industrial usage. Our product gives best performance while use in the factory. Due to high durability & flexibility our pipes & hoses are famous for industrial usage.

Shock Proof

The pipe is non conductor of heat & electricity hence, they have following advantages:

  • Reduce heat loss.
  • No insulation required.
Quick assembly & maintenance free

The pipes, hoses & fittings are light in weight which results in extensive saving of time and laboring being Abrasion/Chemical resistance, free from rusting, pitting or scaling and maintenance-free.

Strong & Stiff

The pipes are specially designed for desire application which meets the required results as follows:

  • Superior strength with stiffness.
  • Flexible Compared to strength & stiffness.
Ultraviolet Resistance

The pipes, hoses & fittings are furnished with extra benefits of UV stabilizers. They have the following advantages:

  • Resists direct connection of UV rays to internal transporting material.
  • No discoloring of pipe in external atmosphere.
Chemical Resistance

The pipes & hoses have special characteristics which offers excellent resistance to great number of chemical like strong mineral acids, bases, & toxic chemicals.

PE-X Pipes & Fittings Joining Instructions

Cutting

Cut the pipe vertically by pex pipe cutter. Make sure to cut it quickly and precisely.

Selecting PEX fitting and jaw

Choose the right size of PEX fitting and jaw of the crimping tool.

Sleeving

Put the copper crimp ring over the PEX pipe at the open end. Later, insert the PEX fitting body into the pex pipe until the shoulder of the fitting reach the pipe, make sure the insert is completely inside the pipe, and the contact between fitting and PEX pipe is clean and free of impurity.

Pressing

Open the crimping tool and put the PEX fitting into the jaw. Press the jaw until it closes completely. While pressing, make sure the crimping jaw is vertical to the pipe, the pressing contact must be free of impurity.

Checking

Use the GO/NO GO gauge to check whether the pressing is completed. If the crimp ring slides into the "GO" slot, but stops at the shoulder in the "GO" slot, then the pressing is acceptable.
