Failures during pressure testing are unpredictable and may cause parts to be propelled in any direction. Some diaphragm seal designs use b40.00 rings to support clamping forces on nonmetallic lower housings.

Pressure Gauge ASME B

Promoting, selling, recruiting, coursework and thesis posting is forbidden. Wakeman, Smith Equipment Mfg. The following are types of temperature: The following parts are in contact with the medium: Alloy an alloy that can be heat treated to control TECthe error caused by temperature change will be approximately the percentage values given by the following formula: Input conditions should be monitored adjacent to the gauge mounting. When incorporated, requirements of para.

This sag may be prevented by attaching a low awme source to the process side of the seal to support the diaphragm. Accuracy may be degraded even if leakage has not b40.010 see error, fatigue. Standards shall have nominal errors no greater than?

On dials for all other grades, take up may be incorporated. The diaphragm housing corresponds to the size of the sealing face of a standard flange. The following is a list of compound pressure: Statistical methods, alternate procedures, or both, may be used when agreed to by the supplier and user. Gauges used on oxygen regulators shall comply with cleanliness Level IV or better.

There are currently no documents on your wish list. I’ll venture a comment in the absence of any other over 2 months. If the user requires detailed assistance, specify items listed in para. If the temperature condition is stable and a more accurate indication is required, recalibration may be appropriate. Above this pressure, 1? The user should inform the gauge supplier of the installation conditions so that the appropriate element materials can be selected.


The maximum outside diameter of the flush mounting rings shall overlap the panel hole by no more than 0.

When the valves are positioned as shown in Fig. If the external atmosphere contains corrosive elements, other materials may be required [see Fig. As all these materials are slightly compressible, bolts must be tightened evenly. The addition of a seal may reduce asmf or sensitivity or both.

Exposed components may be insulated, heated, or cooled to reduce the effects of ambient temperature variations. The filled capillary is then assembled to the instrument and seal in the same manner as the seal and instrument assembly described in para. Liquid-filled cases may be either open front or solid front types. Specific applications may require design variations with ame to case construction.

8008A Pressure Gauge meets EN837-1 and ASME B40.100 standards.

The most common mode of vibration failure is wear of mechanical components because of high cyclic loading caused by vibration. Any loss of fill fluid will result in significant errors or complete failure to transmit xsme to the instrument. The full-scale pressure of the gauge selected should be approximately 2 times the intended operating pressure. The gauge shall also be tested periodically for leakage of the pressure element assembly at full scale pressure.

The pressure gauge shall show no evidence of improper operation, failure, or damage. Repeatability can be determined from the data obtained in para. See recommendations in para. However, if it is incorporated, it shall be readily apparent at what pressure the graduations start. The width of the pointer tip shall not be greater than the width of the minor graduation lines.

DO NOT stand in front of or behind the pressure gauges when applying cylinder pressure to the regulator. Some of these specific service 4b0.100 are listed in paras.


Failure to do so may result in loss of accuracy, excessive friction, or mechanical damage to the b40.1000 element or case. The nominal gauge sizes are 11? If threaded plastic bottom housings are required, care must be taken to avoid over-tightening the process connection, which could cause failure of the housing after a period of time.

Ranges Vacuum 30″ Hg Pressure from 15 psi 1 bar to 20, psi 1, bar all ranges not available in 0. Dual scale dials are useful where gauges are employed on equipment that may be used internationally, or where users plan to convert from one unit of measure to another over a period of time. Flanged seals include a mounting flange that assists when aligning the diaphragm with the process connection.

Statistical methods or alternate test procedures, or both, may be used when agreed to by the supplier and the user. For example, the span of 30 in. See Table 2 and para. The pressure connection shall be sealed to prevent penetration into the asje element. Installation of the gauge should be accomplished by tightening the pressure connection using the wrench flats b40.100 provided.

DO NOT install a low pressure gauge b40100 the high pressure port on a regulator. The proposed code or standard was made available for public review and comment that asje an opportunity for additional public input from industry, academia, regulatory agencies, and the public-at-large. Sanitary seals are quick disconnect types, where the upper and lower housings are held together by a unique clamp, permitting ease of dismantling and cleaning [see Fig.
