Valsir advises against this! The welding temperature is slightly higher and the additive inserted to make the PP flame-retardant renders the weld brittle.

Pipe and fittings can be stored outside temporarily if they are covered and shielded from the sun. The plastic does not contain UV stabilizers and the sun can cause hardening of the surface of the plastic that may interfere with proper joint sealing.

Yes! PP and HDPE pipes and fittings are manufactured in compliance with current regulations and have dimensions that are mutually compatible. This is confirmed by the fact that the Valsir HDPE traps are normally installed in systems made using PP pipes and vice versa.

Yes! It is necessary to know the diameters to be connected and to define whether the pipes to be connected together have a socket or otherwise.

Unfortunately, most plumbing stores don't carry HDPE - often times the store employees have never even heard of it. Usually it can only be found at large industrial plumbing supply places. You can also purchased pre-cut, plugged pieces of HDPE pipe from Pyrogear.net, which specializes in making mortars for fireworks.

Definitive Sealing: by welding the Valsir sealing cover (art. 342). Non-definitive sealing: solution A: by welding the Valsir sealing cap (art. 340). Solution B: by welding the Valsir collar (art. 347) then, using the Valsir free flange (art. .45), the corresponding set of Valsir bolts (art. 341), the Valsir sealing gasket (art. 343) and the Valsir blind flange (art. 346).

Other's pipe can but not fittings due to unique design of the Zurn fittings being able to accept either mechanical or fusion seals. The Zurn groover must also be used with our mechanical joints.

Pipe fittings are identified by their material of construction, inner and outer diameter of the pipe, and the type of fitting whether threaded or slip, male or female.

High Density Poly Ethene but most commonly known as Polythene. One of the most common plastics you use in daily life it has an oily-type finish. Some of the original Prototype Stunt Stormtrooper Helmets were made in HDPE as Andrew Ainsworth (the original maker of the helmets) had some of this plastic in stock as he was making Garden ware and Fishponds. It was a khaki-coloured plastic and due to its oily nature it was a bit of a struggle getting the white paint to stick to it.

A - 25mm ID alkythene for the inlet pipe for which we supply the fittings in the price of the windmill.

The program looks up valve and fitting information in a valve table shipped with the program. The table contains all the valves and fittings found in the Crane Technical Paper 410. Specialty valve and fitting tables are available from selected manufacturers. Back To Top

Fusion of polyethylene and polypropylene pipe will not work; the materials are not compatible. However, PE pipe can be joined by a mechanical joint.

No. Although most modern boilers have a high limit thermostat, residual heat can be conducted by the heat exchanger. Unless the boiler manufacturer states otherwise, a minimum of 1 metre run of pipe from the boiler casing should be copper. This recommendation includes the cold water mains supply to a combi boiler.

For Speedfit Pipe and those fittings suitable for central heating, the maximum working temperature is 92˚C. The products will withstand up to 114˚C intermittently for short periods if there is a boiler or heater malfunction. Products such as flexi hoses, stop valves and washing machine taps that have been designed for plumbing rather than heating situations are suitable for a maximum 65˚C.

John Guest fittings can be used with any quality piping system that conforms to BS7291, this standard defines the allowable tolerances on the outside diameter of the pipe. As the internal diameter may vary from manufacturer to manufacturer it is important that the appropriate pipe insert from the pipe supplier is fitted.

Astral CPVC has a flash ignition temperature of 900?F which is the lowest temperature at which sufficient combustion gas is evolved that can be ignited by a small external flame. Many other ordinary combustibles, such as wood, ignite at 500?F or less. Astral CPVC will not sustain burning. It must be forced to burn due to its very high Limiting Oxygen Index (LOI) of 60. LOI is the percentage of oxygen needed in an atmosphere to support combustion.

Pipe fittings are used to connect pipes. There are different varieties of pipe fittings made of various materials and available in various shapes and sizes. Pipe adapters, couplings, elbows, tees, sleeves, flanges, bulkhead fittings, reducers, valves etc. are all different types of pipe fittings.

Standards are certain authentication given in reference to manufacture and installation of the product . Some common standards are BSP, NPT, ANSI, ASME etc.

No. The noticeable line is not a crack. This you can test by trying to open the crack. If you are unable to open it up by pulling on the part then that is knit-line which is an intrinsic part of the injection-molding process. A knit-line will not impact the integrity of the pipe fitting.

Male threaded: Threads on the outside. They are made to screw into the inside of a larger diameter pipe end with internal threading.
