The pressure in the pipe system pressure test

crimping Types: air or water?

pressure crimping crimping itself monitors the quality of pipe lines and communications.The process occurs in the small blank interval which separates from the base line and after subjected to pressure.

Press pipes for sewage and vodoproprovodnoy, the heating system is due to the space environment in connection with a certain amount of air and water, which allows to maintain in the pipe pressure required to press.When the test tube and its tightness behind intact, it can safely be operated as intended.But if the system "collapsed" the entire structure must be modified.

reasons for crimping

Before you hand over the pipe for further work, they are tested and tested using a variety of techniques.

crimping succumbed to pipe couplings that require precise docking.Because the pipe joints and fittings are the weakest in the pipe system.

Besides additional reason for exploring a seasonally crimping operation of the system.Thus, before you put in action all the details, check all components of the heating duct.

A kanalizatsiydavlenie for plastic molding and almost certainly on its implementation depends on how integrity is the connection of pipelines.

second method of preparation crimping pipe for water has several laws.The pipe is already in the water, so try to protect it from leaks no sense.In this case, it is important to establish a certain depth of water intake from a well from which water quality is dependent: the more, the better.

crimping process water pipes and heating

ensure the integrity and quality of communication by means of the press can be neskolkoneskolko processes:

• Controlled land cover and sealed.Phase means the segment branch pipe from the main water system.Covers all existing taps and valves, which are in the work area.To close the sewer use rubber, wood and plastic plugs.
• pressure is pumped out of the work area to connect to the source.The source appears pump for crimping the pipe or the most common pump that circulates the water in the system.

pump connected to the nozzle, and a few additional processes:

1. Each battery fixed taps with which opressovuyut heating system.
2. A crane pipe hot and cold water and compressed water.
3. pump nozzle is placed in the audit, mounted in 40-50 meters from the discharge pipe.And so it is done pressing sewage communications.

This type of work has great significance pump power.As the pump with a small capacity for a long time will be tested, can not provide a sufficient amount of air, after the can impair the tightness joint.

pump for crimping selected depending on the size of the pipeline.For example, the home plumbing system can operate with injection of 3 liters of fluid per minute.

• air and water is pumped into the system and made their control by available funds.The crucial process takes place through the injection pump airs liquid so that air or liquid is not returned in the opposite direction injection.

In this case, the pressure is regulated and even material from which the pipe.So for cast-iron pipes peculiar pressure of 1.5 atmospheres, and for plastic - up to 2 atmospheres, also for pressurized products - up to 15 atmospheres.

With conventional measuring gauge crimping pressure and is regulated by the launch of the water or air.Indicators gauge fixed, if necessary.

gauge has a back pressure valve, and must be for him, so you can easily find the results.

Crimping pipes and control takes place in several steps:

• download Air controlled manometer.
• When the internal pressure reaches a certain indications supercharger or pump switched off.
• of gaining the first pressure reading is fixed by expectations, that is, after 8 hours the pressure is stabilized.
• After the specified time check the conformity of the first reading on the pressure gauge and current.

is called the Hermetic system in which there is no difference between the first pressure and the latest figures.If not, the system should be further developed and improved.
