Corrugated Stainless Steel Tubing (CSST) is a flexible, stainless steel tube used to supply natural gas and liquid petroleum gas in residential, commercial and industrial structures. Coated with an exterior plastic coating, CSST is usually routed beneath, through and alongside floor joists in your basement, trenching, inside interior wall cavities and on top of ceiling joists in ceiling spaces. It has a non-conductive plastic jacket. By using stainless steel with high corrosion resistance in the construction of the tubing ensures safety and service life reaching 50 years. The inner stainless steel layer of typical residential CSST is .2 to .3 mm. CSST features many benefits over the traditional method in its durability and practicality. CSST has a proven resistance to leaks due to far fewer connections made during installation. When black steel pipe is installed, every time the pipe changes direction, a joint needs to be fitted and checked for leaks. CSST offers flexibility and is able to be snaked through walls and around obstacles with fittings placed only at the ends of the run. Another benefit of this material is the amount of installation time it saves. By most estimates, CSST can be installed in a third of the time it takes to install black steel pipe. Even though CSST is more expensive than the traditional black steel pipe, its overall cost is less when factoring in labor and installation. With CSST’s flexible design, leakages caused by earthquakes or buildings subsidence may be minimised. CCST Gas piping systems should be bonded to the electrical service grounding electrode system according to the applicable standards.IMPORTANT NOTES•The installation must be done by SAQCC Registered Gas Practitioner in accordance with SANS 10087-1 for LPG and 827 for NG.•Care should be taken not to damage the tubing and fittings when transporting or shipping the goods.•Thorough inspection of the tubing should be conducted prior to the installation to make sure that there is no visable defects or damage to the tubing and fittings.•The correct tooling should be used when installing a Gas System in CSST.•CSST tubing must not be installed in direct sunlight, in a damp area or in a weak acid environment where the ph level is less than 7 such as swimming pool areas and chemical plants.
PEX-AL-PEX pipes or PEX/Aluminum/PEX pipes are made with a layer of aluminum sandwiched between two layers of PEX. The metal layer serves as an oxygen barrier, stopping the oxygen diffusion through the polymer matrix. The aluminum layer is thin, typically 1 or 2mm, and provides some rigidity to the tubes such that when bent it retains the shape formed (normal PEX tube will spring back to straight) The aluminum layer also provides additional structural rigidity such that the tube will be suitable for higher safe operating temperatures and pressures.
