Is it correct there are various types of Dual Containment Hoses?
Yes, there are two types of Dual Containment Hose: Standard and Detect Leak.
PF-Detect Leak Detectable Dual Contained Hose
What internal diameters are available in dual contained hose?
The ID of the Dual Containment Hose is 6mm-50mm. Allmach has exclusive rights to these sizes.
What are the maximum length of pipe available?
The product is supplied on drums of 450 – 500 metres. However, we can supply lengths of up to 700 metres. Common lengths of 150, 200, 250 metres are readily available, and each coil is tested for electric conductivity and certified before delivery.
What chemicals can be transported through the product?
The product comes with various material inners such as PVC, LDPE and PTFE to cover resistance of most common chemicals used in dosing such as Sodium Hypochlorite, Ferric and Caustic. Full chemical details are always requested including concentrations to ensure that the product is fully fit for purpose. Full chemical resistance charts are available on request.
Are catch-pots needed when using PF-Detect?
No, using PF-Detect eliminates the need for catch-pots because an audible and visual alarm will be triggered in the unlikely event of a leak. The system can also be wired into the main control PLC and set to automatically shut off the pump, dramatically reducing any impact on the environment due to leaking chemicals.
Allmach is a piping wholesaler, therefore we do not offer installation. However, we have plenty of resellers Australia-wide who can assist you with your supply & install needs. Contact us for more details about installers.
Can Allmach cut pipes to order?
Yes, we can organise for your pipe to be cut to order. However, we only sell the pipe as complete lengths so it will incur a cutting fee.
Is there a visual indication when the fittings are successfully pressed?
Yes, SurePress fittings have two indicators. One coloured ring which is destroyed and falls away once the press cycle is complete, and a ‘Leak path O-ring’ which will allow a slight leakage of fluid/gas until the press cycle is complete.
Does Allmach offer tooling for the installation of SurePress pipework?
Yes, we have a large range of tooling available for sale or hire. Our hire fleet is constantly being upgraded and by mid-2021 all our press tooling will have data logging and Bluetooth connectivity to allow the contractors to download all press data for their projects.
How do I cut SurePress pipe?
SurePress Stainless & Carbon steel tube can be cut with a manual wheel cutter. Please speak with our team to ensure you have the correct wheel option. We also have options for a powered cutter for larger sizes. Contact us to us for options.
Is the Surepress system price-competitive compared to threaded & roll groove joining methods?
As the Surepress system is 10 times faster to install than traditional copper pipes and requires no threading, hemping or gluing, it is much more economical to install. Press fitted pipe joints are fast, easy and risk-free. The result of the operation is “definitive” since it is no longer possible to separate the components and return them to the original condition.
Leak path O-ring
Are Surepress O-rings fire rated and will they degrade over time?
Surepress O-rings are fire rated and have passed the RINA fire test. They are
made of black EPDM and are resistant to ageing, heat and chemical additives.
Press indicator on fittings
What's the advantage of the red press indicators on SurePress carbon steel fittings?
When the fitting is crimped on Surepress carbon steel tube, the red press indicator falls off to show the fitting has been crimped. This safety feature is unique in Australia.
Thin walled tube
Please explain why thin-walled tube is allowed when the specification calls for thick-walled pipe?
SurePress thin-walled tube has been approved by Activfire for use in fire sprinkler and
hydrant systems because it is made to a high specification and is electroplated which allows for a thinner-walled tube. The tube would be easier to handle and cut because of this.
Sch-80 PVC is resistant to a variety of chemicals and can handle most acids, oxidants, salts, bases, etc. It is lightweight, easy to handle and install. Unlike metals, PVC is corrosion resistant and will not rust.
Is Sch-80 PVC pipe UV resistant?
Sch-80 PVC pipe & fittings are manufactured using additives to provide UV stabilization. When exposed to direct sunlight, PVC will eventually show discolouration over a period of time. The discolouration will not compromise the system and is cosmetic in nature and will only occur where there is direct exposure to UV radiation.
What is the maximum pressure and temperature rating of Sch-80 pipe?
The pressure rating of Sch-80 varies and is size-dependent. Typical ratings are 60-16bar for sizes 3/8-12″. These ratings are de-rated the higher the operating temperature. The operating temperature range is 0-60°C.
What is the difference between Sch-40 pipe & Sch-80pipe?
Sch-80 pipe has a thicker wall than that of Sch-40 and is primarily used in harsher environments than Sch-40. The thicker wall can handle higher pressure applications and is suitable for heavy industrial applications.
The Allmach range of piping systems is available from all leading rural, irrigation, hardware, plumbing, civil, mining and industrial merchant retail outlets. To become a distributor of our piping systems, please contact our customer service team.
