The Middle High German word brīdel , which can be translated as “rein,” came into French as bride . This term arrived in our language as a bridle : this is the name, in the field of horse riding , of the set of bits and reins that is placed on the horse 's head and that allows it to be directed.
Equine control
The bridle, in this way, is made up of the bits or brakes and the reins or straps that are used to control a horse. The framework of the straps that serves to secure the bits and that is part of the bridle is known as the bridle .
Through the bridle an action is exerted on the animal's mouth . It is important to adjust the elements properly and maintain delicate contact.
The precinct
A seal that is used to hold cables or to establish a lock that makes opening a box difficult, among many other uses, is also called a flange. These ties can generally be used for other tightening and containment tasks.
Pipe union
Flanges, on the other hand, are the parts that make it possible to join two pipes or a pipe and a pump, a valve or other object in a pipe . The coupling is achieved by using bolts or screws that fix the flange to the structures in question, although welding can also be used.
Flange with welding neck
This product is also known by its English name, Welding Neck Flange , and stands out for the presence of an extensive cone-shaped neck, which ends in the equivalent diameter of the pipe on which it is to be mounted. To do this, as its name indicates, welding work must be carried out between both parts . The use of this flange results in a very reliable and stable conduit, with a very low percentage of probability of turbulence in the liquids that pass through it.
Its characteristics, such as the fluid transition between its thickness and that of the pipe and the extension of its neck, make this type of flanges especially strong and ideal for use in connections that are subjected to bending stresses, due to phenomena such as contraction and the expansion of the lines.
It is especially recommended for services that are affected by high temperatures or high pressure levels , or by carrying toxic, corrosive or flammable fluids. In addition, they are ideal for pipes in which it is important that large leaks do not occur.
sliding flange
It is preferred over other types because it is cheaper and easier to install. It is also known as Slip On Flange , and is sold in a wide variety of diameters. To join it with the pipe, a double weld must be made: the pipe is inserted into the flange and both the outer edges and the inner ends are welded. Its resistance under pressure is calculated to be two thirds of that of a welding neck.
Another difference with respect to the previous type is that it does not have a seat to rest on the tube, which is why it is necessary to weld the joint twice . However, since they do not require precision in cutting the pipes, it is easier to align them with them. They are usually used for liquids that circulate at low pressure and do not present a considerable risk if leaked.
Novel by Paulo Coelho
“Brida” , finally, is the title of a novel by Brazilian Paulo Coelho . The work, published in 1990 , revolves around a young woman named Brida who is interested in magic and meets a man who becomes her guide.
