The fire HDPE pipe groove depth and the pipe joint (groove connection) must conform to the requirements of the groove type pipe joint. For groove pipe joint with a nominal diameter of DN250 or less, the maximum working pressure is 2.5 MPa, while for the pipe joint with a nominal diameter of DN300 or more, the maximum working pressure is 1.6 MPa.
If a pipe bursts in the ceiling or floor it can be some time before you notice and all too often the first you know is when the bulge appears or the water flows in a torrent. The potential water loss from burst pipes in your house can be as much as 400 litres, that’s 2 full baths an hour.
PIPE FITTING, OINT AN E 41 a pluer must also have knowledge of the various pipe fittings like elbow, union, gasket, etc., joints and valves, and where these should be used while carrying out the tasks. Not only does this help in smooth functioning, but
The usual length of a pipe section is 12 ft, but lengths up to 20 ft can be obtained. Cast iron pipe is made in several thickness classes for various pressures up to a maximum of 350 psi. Cast-iron pipes are usually dipped in a bituminous compound for protection against corrosion and to improve their hydraulic qualities; larger sizes may be provided with a lining of cement mortar.
Inspection and Test Plan The inspection and test plan article provides you with information about inspections and tests which are used in manufacturing shops. In addition there are lots of linked articles which provides specific information about inspection and test plan for each equipment type. Puhui Pipe manufacturer in China
installed with fire hydrants, the size of the water main may be governed by the flow to meet fire fighting purpose as required by the Fire Services Department. Designers should, as far as practicable, avoid using the same pipe size and material for both fresh and
18/5/2004· I believe it refers to the fact that in presence of a discharge expansion joint, a force equal pressure times area of discharge pipe may be applied to pump casing. i.e. given much higher E of HDPE than the bellows, whatever movement occurs is not enough
5. FIRE FIGHTING MEASURES Suitable Extinguishing Media As appropriate for surrounding fire. Extinguish preferably with foam, carbon Dioxide, water/water mist or dry chemical. Unsuitable Extinguishing Media Do not use high volume water jet or waterspray.
Fire fighting pipe is a type of normal carbon HDPE pipe used to convey fire suppression agent such as water or gas. Usually it is red in color. But light-wall pipes have a galvanized exterior of a silvery appearance. Installation of red HDPE pipe is limited to wet pipe Puhui Pipe manufacturer in China

Chapter 9 PE Pipe Joining Procedures 328 The principle of heat fusion is to heat two surfaces to a designated temperature, then fuse them together by appliion of a sufficient force. This force causes the melted materials to flow and mix, thereby resulting in fusion.

• good pipe alignment during assely of a pipe run prevents ‘locked-in’ stress • the use of expansion (mechanical) joints, such as dresser-type joints, is restricted to loions where pipes move because of thermal expansion or contraction, or ship bending.
Typical expansion ratios are about 50:1, i.e. a 1mm thick coating will expand to about 50mm when affected by fire. Detailed guidance on the specifiion and installation of site applied, thin film intumescent coatings is available from the Association for Specialist Fire Protection [1] .

Dry pipe system air pressure should normally be 20 psi (1.4 bar) above the trip pressure of the dry pipe valve, usually in the range of 40 (2.75 to 3.1 -45 psi bar). If the pressure is high or low, it should be corrected. Check each pre-action system for proper supervisory
