Its name is Explosion-proof car
In fact, in our daily lives, we will see various types of special vehicles, but we often do not know their unique names. For example, if there is a special vehicle with the word “no fireworks†on it, we really think that This is just a sign on an ordinary truck. It is not. It has a loud name, called an explosion-proof car. Explosion-proof vehicles, also known as blasting equipment transport vehicles, specialize in the transport of some explosive items, such as gunpowder, special pyrotechnic products, blasting explosives, also ignited medium. And from the beginning of the flat transport successfully converted to van transport, more reliable and safer. In fact, the most important and most important design of explosion-proof cars is inside the compartment. Protection 1: The body is a sturdy double-layered metal skeleton structure. The exterior is a cold-rolled Steel Plate. The interior uses aluminum alloy plates, and the middle layer is made of heat-insulating and flame-retardant materials. The second protection is a smoke alarm, which is installed on the top of the car. Once a fire smoke is sensed, it will be automatically alarmed in the cab to ensure that drivers or pedestrians can promptly detect and deal with it in time. The third protection is an anti-personal burglar alarm installed at the top of the door frame. Once the car door is opened, an alarm sound will be issued in the cab. If not, the control switch can be turned off. Provides convenience for drivers and ensures that explosion-proof cars are under their control. Secondly, the anti-explosion vehicle uses a front-mounted exhaust device and an exhaust spark extinguisher to prevent the heat generated by the vehicle itself from reacting badly to the explosive. In addition, two electrostatically conductive tapes are installed on the chassis, and safety devices such as marker lamps and portable fire extinguishers are installed on the outside of the car. With regard to the decoration of the carriages, there are also hints of yellow and words such as “no fireworks†and “burst†to warn the vehicles and the masses. Even if it is an explosion-proof car, there are still two sides of danger prevention and danger. Therefore, the driver must know how to maintain and regularly check the car to ensure the safety of the car and also to ensure his own safety. Xiao Bianji: I sincerely hope that explosion-proof vehicles will become more and more mature, and I hope we can truly apply the "explosion-proof" concept to a wide range of transportation tools.
Forged pipe fittings
Different from butt weld fittings, some pipe fittings are produced by forging method, they are called forged pipe fittings, including forged O-lets, nipple, union, plug,coupling and so on. According to difference in connection type, there are socket weld pipe fittings and threaded pipe fittings.They belong to high pressure forged pipes, pressure for SW fittings shall be 3000# ,6000# ,9000#. The pressure of forged NPT fittings shall be 2000#,3000#,6000#.
Forged Elbows, tees,crosses, couplings,half-couplings,plug,bushing are covered by standard ASME B16.11. Their size is not very big. The size for ASME B16.11 forged fittings is 1/8``-4``.
As for branch outlet fittings, the manufacture standard for weldolet, sockolet, threadolet is MSS SP-97.
