Introduction:
Brief introduction: New high double sealing sounding product process
The general requirement of the ultraistic transmission method for the sounding steel pipe is that the joint is firm and the sealing ring is plasma proof. The pipe wall is flat and no wrinkle and deformation. The pipe body is straight and not deflection. The internal of pipe is unblocked.
When the material and the installation process of the sounding test steel pipe is so bad that it will cause some plasma leak,jam in the pipe, break, bending, sinking, deformation etc, which will bring some effect to the complete testing pile base of ultraistic transmission method, even can not proceed the ultraistic transmission method
   
High double sealing hydraulic pressure sounding test steel pipe has two protruding groove on the end of the socket part. There are sealing ring inside the protruding groove. The socket end of this product will be put into 10cm of female end. Then this two protruding groove will be squeezed by the special use hydraulic pressure pincers. The squeezing part will be deformed and shrink because of the outside force. This two protruding outside pipe fittings will be sinned into the inside pipe fittings which will realize the dependable joint. At the same time, the rubber sealing ring will attach to the part between the two pipe fittings after squeezing so that it will have the better function of double assurance sealing.
The advantage of the high double sealing hydraulic pressure sounding test steel pipe is that it considers all of the related factors in the course of usage and reach the leading performance in China, even all of world

Cangzhou Leading Fly steel pipe Co.,Ltd supply the high double sealing hydraulic pressure sounding test pipe that is strictly produced as per the enterprise standard Q/368658BYD-2008. And this standard has so much improvement than JT/T 705-2007.

Advantage

The sealing ring will be longitudinally deformed and shrinked and then attached between the two layers of steel pipe. In that way, the sealing function will be best. And this kind of design also increases the insurance co efficient.

The joint part will be squeezed into big in the two ends, small in the middle, which is fixed one time and avoid the probability of loose joint. The anti drawing force and anti twist are stable and excellent. The protruding part becomes arc and the protruding degree is small. This will effectively avoid the collision with the vibrorammer and conduit pipe.
The muff-coupling is plugged fully which guarantees the straightness of the joint.

High double sealing hydraulic pressure sounding test pipe also have the other two distinct advantages and one set of strict guarantee measure except the above mentioned leading performance.

This two advantages is convenience and economy

Convenience: it will completely avoid the welding on site, threading or or rolling and no need to use the electricity assistance. It only use the assorted pressure tool and finish all of the work by hand. The installment will be finished one time and save so much time and manual force

Economy: it can save 2/3 of steel pipe in quantity compared with 573.5mm as per the usual design. In this way, the cost is obviously decreased. As the most convenient sounding test steel pipe in operation in China, it saves so much manpower and improves the working efficiency. In the entire thin wall sounding test pipe of different kind joint, this kind of steel pipe can be cut in random length on the working site. There is no short pipe or material waste
. The actual total cost is obviously decreased.

Repair and warranty: Cangzhou Leadingfly Steel Pipe Co.,Ltd has one set of testing warranty measure in order to show our confidence for our product and want to be responsible for the client.
