5 1/2" stainless drift mandrel for pipe test

Closed water test airbag(Pipeline blocking airbag.) s a kind of portable rubber airbag product developed by our factory to block pipelines. The product is simple to operate, fast to block, and resistant to aging.It is an indispensable product for closed-water experiments of sewage pipes, building drainage pipes, and emergency repairs.

Characteristics

(1) The closed water test airbag has uniform thickness and strong airtightness. The joints are passed through the top of the hot-press vulcanizing machine by means of lap joints to make the joints stronger and ensure the number of uses.

(2) The closed-water test airbag can be inflated with an inflator for small airbags, and for large water-sealing airbags made to order, the interface must be connected to an air pump to inflate.

(3) The closed-water test airbag can be reused many times, and should be stored in a ventilated and cool place.

Advantages

Good air tightness, strong elasticity, high wear resistance, high acid resistance, aging resistance, cheaper price, better quality, more complete functions, more intuitive detection, etc.

Usage

It can be used for cast iron, glass fiber reinforced plastic or plastic pipes, threads Pipes and other pipes in the pipeline. Pipeline water blocking airbags are easy to operate, intuitive to check, and can be checked in time during the construction process and eliminate quality hazards

Use Method

1. Preparation: Check the leak of tools for the connection of leaking airbags and accessories in municipal sewage pipelines. Use an inflator (air pump) to inflate the airbag, and the air pressure shall not exceed 0.15MAP. Check whether the airbag is leaking.

2. Open the port of the pipe, slowly place the air bag inside the desired position from this port, and then inflate the air bag to the pipe to block the leak, and inflate it to an appropriate pressure (usually 0.015MP). Note that the airbag should be avoided to be placed at the joint of the riser pipe fittings, for the following reasons:

(1) There are joints on the inner wall of this place, which affects the tightness of water blocking.

(2) In order to prevent the air bag from inflating to one side and the air pressure can not be hit, if the inflation continues, the pipeline plugging air bag will be broken.

(3) For municipal drainage pipes, sand is required to be cleaned, the inner wall is flat, and no burrs are allowed, otherwise it will affect the water blocking and sealing performance, and even puncture the capsule.

(4) Airbags of various specifications are used in corresponding pipelines, and small ones cannot replace large ones.

3. In order to prevent the airbag from separating from the hose, iron wire should be used to tie the airbag and hose interface tightly or in other ways.

4. When the air pump is used to inflate the pipeline to stop leaking the airbag, the air volume of the air pump should be turned down a little, and a large amount of inflation cannot be continued to prevent the airbag from bursting and causing an accident.

5. In the process of carrying the airbag, do not drag the airbag to prevent damage to the outer wall of the airbag.

6. In engineering operations, always pay attention to the pressure value of the pipeline plugging airbag. If the airbag pressure value drops very slowly, it is not necessary to stop the operation, continue to use the air pump to inflate the airbag to the standard pressure, and wait for the completion of the operation. Then check the airbag or the parts for leaks.

Characteristics

(1) The closed water test airbag has uniform thickness and strong airtightness. The joints are passed through the top of the hot-press vulcanizing machine by means of lap joints to make the joints stronger and ensure the number of uses.

(2) The closed-water test airbag can be inflated with an inflator for small airbags, and for large water-sealing airbags made to order, the interface must be connected to an air pump to inflate.

(3) The airtight test air bag can be used repeatedly and should be stored in a cool and ventilated place.

benefits

Good air tightness, strong elasticity, high wear resistance, acid resistance, aging resistance, low price, better quality, more complete functions, more intuitive detection, etc

usage

It can be used in cast iron, fiberglass reinforced plastic or plastic pipes, threaded pipes and other pipes within pipes. Pipeline water blocking air bag is easy to operate, intuitive inspection, and can be timely inspection and elimination of quality hazards in the construction process

1. Preparation: Check the tools used to leak airbags and accessories in municipal sewer lines for leaks. Use an inflator (air pump) to inflate the airbag at a pressure of no more than 0.15MAP. Check if the airbag is leaking.

2. Open the end of the duct and slowly lower the airbag from this end into the desired position, then inflate the airbag into the duct to stop the leak, and then inflate it to the appropriate pressure (usually 0.015MP). Please note that the airbag should be avoided at the joint of the riser fitting for the following reasons:

(1) there are cracks on the inner wall of the position, which affects the sealing of the water resistance.

(2) In order to prevent the airbag from expanding to the side and avoid the impact of pressure, if it continues to inflate, the airbag with blocked pipeline will rupture.

(3) for municipal drainage pipes, it is necessary to clean up the sand, the inner wall is flat, and no burr is allowed, otherwise it will affect the water resistance and sealing performance, and even puncture the capsule.

(4) Various specifications of airbags are used in the corresponding pipelines. Small airbags can not replace large airbags.

3. To prevent the airbag from separating from the hose, wire should be used to tie the airbag to the hose interface tightly or otherwise.

4. When using an air pump to inflate the pipeline to stop the airbag leakage, the air volume of the air pump should be lowered a little, and a large amount of inflating should not be carried out to prevent the airbag from bursting and causing the airbag leakage. The accident.

5. In the process of carrying the airbag, do not drag the airbag, so as not to damage the outer wall of the airbag.

6. During engineering operation, please always pay attention to the pressure value of the airbag with pipe blockage. If the airbag pressure drops very slowly, you do not need to stop the operation. Continue to inflate the airbag to standard pressure with the air pump and wait for the operation to complete. Then check the airbag or parts for leaks.

Characteristics of the

(1) airbag thickness is uniform and airtightness is strong for closed water quality test. The joint passes through the top of the hot press vulcanizing machine through the lap joint to make the joint stronger and ensure the number of service times.

(2) closed water test air bag can be inflated by small air bag inflator. For customized large water sealed air bag, the interface must be connected to the inflator pump to inflate.

(3) The airtight test air bag can be used repeatedly and should be stored in a cool and ventilated place.
