Range of application: applicable for the set-pressure, setback pressure and sealing tests of direst loaded and pilot-operated safety valves.



Technical Parameters:

Maximum drift diameter: DN400mm

Maximum test pressure: 60Mpa
Pressure test precision: pressure gauge of 0.4 grades (Users can choose a more precise one.)

Test medium: nitrogen, compressed air or clean water (Gas liquid dual-capable one can be designed.)

Functions and Characteristics:

The equipment has advanced design principle. It uses pneumo-hydraulic booster pump as its clamping pressure source and air driven gas booster pump as its test pressure source. A gas cylinder is equipped, which enables the test to be conducted continuously.

â?¢The test pressure is adjustable and the process of pressurization is stable.

â?¢Clamping pressure source and test pressure source can use imported booster pumps from America or Germany, which have a wide range of output pressure.

â?¢All the manual high pressure valves, pipe fittings and connectors are imported ones, which guarantee their pressure levels, safety and reliability. Most gas and liquid media are available.



MAQ-400 /48BA Functions and Characteristics:

Maximum drift diameter: DN400mm

Maximum test pressure: 48Mpa

Pneumatic control hydraulic clamping device is adopted. Clamping force is adjustable. The equipped pressure gauge displays the corresponding clamping force and provides a comparison table between the pressure and the clamping force, which facilitates operators to choose appropriate lamping force according to the safety valve calibration pressure and the drift diameter.

All the valves, pipe fittings and connectors are made of stainless steel.

The test is operated manually and operators record the data.

The system includes two test and calibration tables. One is equipped with two clamping devices. There are totally three clamping devices: one is for safety valves of DN15-DN100; one is for safety valves of DN100-DN200; one is for safety valves of DN200-DN400.

â?¢Various test tools are equipped to meet the needs of customers on different kinds of safety valves.

Surface diameter: 50 mm

Use: stainless steel pressure gauge widely used in petroleum, chemicals, chemical fiber, metallurgy, power plants and other industrial sectors in the decay resistance is higher in the process of measuring the various fluid medium pressure, temperature at 85 íµ following gas liquids pressure applied to strong corrosive stainless steel components for the detection of medium and poor external corrosion environment. Can substitute the general pressure gauges.

DY-2 Butterfly Extensometer
Overview
The butterfly-type extensometer is a mechanical contact-type displacement meter, and is made for measuring the displacement of materials, so as to obtain the indicators of certain mechanical properties.
It has a simple construction and is easy to use, reliable, highly adaptative, economical and durable and recyclable. In addition, the measurement sensitivity may be improved by enlarging the gauge length.
The device is light in weight, clear in scale and compact in structure, and dial gauge and dial indicator are optional according to different accuracy requirements. Therefore, it is a necessary and ideal device for material test.

Main specifications
1. Maximum size of the test piece clamped: Diameter of column piece: 0-25mm; thickness of tabular piece: 0-25mm.
2. Size range of gauge length
3. Optional scales: Dial gauge: Measurement range: 0-30mm, division value: -.01mm; dial indicator: Measurement range: 0-1mm, division value: 0.001mm
4. Accuracy grade of the dial provided: Grade 1

Surface diameter: 60 mm
Case material: sus304 stainless steel
Connecting thread: m14x1.5
Accuracy rating: 2.5
Use: used to measure the copper and copper alloy non-corrosive, non-explosive, not crystal, not precipitate the gas or liquid pressure. The biggest feature is in severe shock in the machine or equipment to normal pressure. Measurement apply intense media pressure shock pulse of the place frequently, work long hours in a state of the pressure on the machinery and equipment, general maintenance pressure gauges.
