Hydrostatic Testing Machine1

Equipment Technical Parameters:

1) Maximum test pressure:5~70MPa(the equipment is designed

 

and manufactured according to user’srequirement on steel pipe OD

 

and testing pressure);

2) Master cylinder(according to the requirements of the pressure,

 

use 1~6pcs),intelligently control thrust of hydraulic master cylinder

 

to be balanced with steel pipe testing pressure.(oil-water balance),

 

total thrust:50~3000ton.

3) The pipe ends sealing form : end face seal, radial seal ( according

 

to user’s requirement ). Advantages and disadvantages:For radial seal,

 

there is 20-30mm testing blind area at ends of pipe, the equipment cost of

 

end face seal is much higher

 

Description

Hydrostatic testing machine
1. Uses and Features:
1)The equipment is used for kinds of steel pipe pressure-bearing and testing non-standard equipment.
It adopts two lifted rollers to hold the tested steel pipe, using the thrust of master cylinder to press the pipe

between the thrust plate and the pressure plate, so that the pipe two ends can be sealed(end face seal or

radial seal). Based on high-volume low-pressure pump to complete the water injection, and then use

high-pressure pump to complete high pressure test.
2) The equipment uses master oil cylinder thrust and smart balance control system(oil-water balance) to do

hydrostatic testing. It adopts PLC programming smart control touch screen operating system, displaying

the test pressure at real-time. Thetesting pressure curve can be automatically printed and also can be stored

in computer hard disk.
3) The equipment is with simple structure, high production efficiency, wide range of product specifications,

movable and lockable  steel pipe pressure head push plate which can test various lengths steel pipes.

The equipment applies to hydrostatictesting for seamless steel pipe, welded steel pipe and spiral welded pipe.


2. Equipment Technical Parameters:
1) Maximum test pressure:5~70MPa(the equipment is designed and manufactured according to user’s

requirement on steel pipe OD and testing pressure);
2) Master cylinder(according to the requirements of the pressure,use 1~6pcs),intelligently control thrust

of hydraulic master cylinder to be balanced with steel pipe testing pressure.(oil-water balance),

total thrust:50~3000ton.
3) The pipe ends sealing form : end face seal, radial seal ( according to user’s requirement ). Advantages and

disadvantages:For radial seal, there is 20-30mm testing blind area at ends of pipe, the equipment cost of

end face seal is much higher
3. Testing Pipe Parameters:
1)Diameter:φ21~φ1420mm;(sectional design and manufacturing the equipment)
2)Length:4~12m;
4. Equipment Structure:
base, thrust plate, pressing push plate, balance pressure crossbeam, master cylinder pressure handpiece, steel pipe

holding device, hydraulic control system, control cabinet, operation desk (touch screen), water pressure control system,

PLC programming  smart control system.
