Steel structures can be used in many
industries such as foundation reinforce, electric power transmission structures
and tubular scaffolding, etc.
A flange can also be a plate or ring to form
a rim at the end of a pipe when fastened to the pipe. A blind flange is a plate
for covering or closing the end of a pipe. A flange joint is a connection of
pipes, where the connecting pieces have flanges by which the parts are bolted
together.
Although the word flange generally refers to
the actual raised rim or lip of a fitting, many flanged plumbing fittings are
themselves known as 'flanges':
There are many
different flange standards to be found worldwide. To allow easy functionality
and interchangeability, these are designed to have standardised dimensions.
Common world standards include ASA/ASME (USA), PN/DIN (European), BS10
(British/Australian), and JIS/KS (Japanese/Korean). In the USA, ANSI stopped
publishing B16.5 in 1996, and the standard is ASME B16.5

When an LED display simultaneously displays multiple noise levels, the lightweight device allows the operator to hear the amplified sound through a high-quality rechargeable wireless Bluetooth headset – all in a small package so that Put it in your shirt pocket.
By storing previous reading information in the built-in memory, Tmic allows the operator to visually compare the current and previously recorded noise levels. The user can thus quickly determine if the noise is caused by a leak, and if it is determined that the leak is caused, the most likely leak location can also be determined. The high quality digital sensor can be placed directly on the tube or coupling with better sensitivity and noise quality levels than mechanical leak bars. If required, Tmic can also provide additional magnetic attachments and attach to a detachable meter extension to access blocked or difficult-to-access areas.
Thanks to its ergonomically robust design and long life of alkaline batteries, Tmic can be used in any situation. It weighs only 180 grams and can be worn in a shirt or trouser pocket. A bright LED flashlight is placed on the head for nighttime use or to view the darkroom. In addition, Tmic has other conveniences, wireless headphones ensure full freedom of movement, and will not entangle the headphone cord. The product's accessories are housed in a sturdy, small box with precision-cut foam to protect all attachments from handling during handling.
Early when the operator leaked from the water pipe, he had already heard the noise from the water in the underground water pipe under the pressure. Contrary to our usual perception, the largest slats do not always produce the strongest noise; large cracks generally produce weaker noise than small cracks. Traditional mechanical leak bars rely only on one of the user's senses: hearing. However, not all the noise generated by the leak can be heard by humans. Therefore, the electroacoustic sensor can amplify the noise below the independent listening threshold and display the result; this is a very valuable tool for viewing the underground leak or confirming the position of the leak before manual excavation.

HWM's new Tmic is a cost-effective monitoring tool that identifies and locates leaks on the waterline that are inaudible to the human ear.
