Elevator safety tips Nowadays, high-rise buildings and super high-rise buildings have become the daily scenes in people's sights. Regardless of whether they are houses or office buildings, elevators have become a means of transport for these high-rise buildings. The recent elevator accidents caused frequent accidents and sounded the alarm for safe elevator rides. The following Xiao Bian told everyone about the safety knowledge of taking the elevator.

1. Escalators As an elevator Escalators are mainly distributed in shopping malls, supermarkets, hospitals, and train stations. Before the boarding, you should tie your shoes tightly, pay attention to the loose, dragging clothing to avoid hanging on the edge of the rung; when stepping on the escalator, step on the border of the yellow line, do not push other people up and down the escalator, and forbid to jump and play on the running steps. Run; Avoid heads and limbs out of the armrest device to prevent impact from ceilings and other objects; prohibit children from climbing on handrails to prevent crushing fingers and damage to hand-held devices; do not stay at the escalator exit to avoid Affect other passengers.

Second, the car elevator When entering the elevator car, if the door is open, remember not to blindly enter. Under normal circumstances, it should be confirmed whether the elevator is parked on the floor and in the leveling position. Especially when the light is not clear at night, it should be noted, otherwise it may cause personnel to fall accidents. When entering or exiting the car, it is not allowed to stay between the hall and the car door.

Third, emergency self-help Tips When being trapped in the elevator, do not perform dangerous actions such as tapping the elevator, opening the elevator door, or climbing to the top of the car. The amount of oxygen in the elevator is sufficient. It should be as calm as possible and there should be no risk of oxygen-deprivation and suffocation within a short time. You can use the call device in the elevator, or call an acquaintance on your mobile phone for help and wait patiently for assistance. In the event of an emergency, the following points can be saved.

1. When there is an unexpected situation, no matter how many floors there are, the buttons on each floor should be pressed. When the emergency power is turned on, the elevator can immediately stop falling.

2. The entire back and head are in close contact with the inner wall of the elevator. The line is in a straight line. Use the elevator wall as a protection for the spine.

3. If there is a handrail in the elevator, use one hand to pull the handrail. This is to fix the position and prevent a fall due to an unstable center of gravity.

4. The knee is in a bent position, which is the most important, because the ligament is the most abundant tissue in the human body, so borrow knee bending to withstand the heavy blow pressure.

5. Lifting your heel is lameness. If the number of people in an elevator is small, it is best to hold both arms in the armrest or attach the elevator wall.

ANSI Flange

ASME B16.5 Pipe Flanges and Flanged Fittings: NPS 1/2 through NPS 24 Metric/Inch Standard covers pressure-temperature ratings, materials, dimensions, tolerances, marking, testing, and methods of designating openings for pipe flanges and flanged fittings. Included are:
(1) flanges with rating class designations 150, 300, 400, 600, 900, and 1500 in sizes NPS 1/2 through NPS 24 and flanges with rating class designation 2500 in sizes NPS 1/2 through NPS 12, with requirements given in both metric and U.S. Customary units with diameter of bolts and flange bolt holes expressed in inch units;
(2) flanged fittings with rating class designation 150 and 300 in sizes NPS 1/2 through NPS 24, with requirements given in both metric and U.S. Customary units with diameter of bolts and flange bolt holes expressed in inch units;
(3) flanged fittings with rating class designation 400, 600, 900, and 1500 in sizes NPS 1/2 through NPS 24 and flanged fittings with rating class designation 2500 in sizes NPS 1/2 through NPS 12 that are acknowledged in Non-Mandatory Appendix E in which only U.S. Customary units are provided.

B16.5 is limited to flanges and flanged fittings made from cast or forged materials, and blind flanges and certain reducing flanges made from cast, forged, or plate materials. Also included in this Standard are requirements and recommendations regarding flange bolting, flange gaskets, and flange joints.
This Standard is to be used in conjunction with equipment described in other volumes of the ASME B16 Series of Standards as well as with other ASME standards, such as the Boiler and Pressure Vessel Code and the B31 Piping Codes.

Careful application of these B16 Standards will help users to comply with applicable regulations within their jurisdictions, while achieving the operational, cost and safety benefits to be gained from the many industry best-practices detailed within these volumes.

Intended for manufacturers, owners, employers, users and others concerned with the specification, buying, maintenance, training and safe use of valves with pressure equipment, plus all potential governing entities.
