Tube pipe - dual connections Virola pipe fittings and connections

Virola double tube accessories

There are 3 main mechanical methods to connect two lengths of pipe together.

Broken fittings - where the end of the tube is abocinado using a tool, and then inside of a nut, the sleeve and body.Single Virola accessories - where the ends of the tube in a connection with a single compression ring, a body and nut are placed.Virola accessories double - where the ends of the tube on a connection with separate compression are placed two rings, body, and the nut.(Also known as the twins connection Virola, this is not strictly correct because the two rings are of different shape and length.)

For the purposes of this article will focus on double Virola mounting.

This style of connection, like all others, has a basic function. Securely unite together tubes in a safe place, seal tightly together. Close tolerance machining on CNC machines high quality allows the consistent production of all components.

Double Virola connection has the ability to lock in the tube with a function of 'double bite'. each ring bites the tube to two separate areas of sealing.This style connection makes it without transmitting pair or twisting tube ensure you tube not become 'stressed'. Wherefore, maintaining the mechanical properties of the tube. Most sealing point occurs at the bottom of the pillars of tube. The Stirrup has an angle pipe is forced to ring when biting and moving in the tube.

Stainless steel fittings solve the problem of the humiliating using silver plates.Internal parts nut are the only areas that are covered.

Materials such as high nickel alloy, high temperature, duplex and super-dúplex alloys are coated with an agent anti-gall similarly. However, molybdenum sulphide can be used as a material alternativa.estos are selected to compatible media smooth inside of them.
Chemical stability the ideal situation is that pipe and fittings are manufactured from the same type of material.

There are strict mounting instructions to proceed with this type of product.
The rule provides that you for most sizes 1-1/4 nut, rotations from the strict finger position, will give the correct joint stamp permissible apretado.Es to follow 'snug' connection if a minor loss, but this is not normally necessary.

When you need access to any system of these accessories provide an excellent point 'robbery'.
Joint can be made and re-made many times above without loss of integrity, providing you follow the instructions for proper installation of sealing.

The strength of the connection is such that the content tube is burst before the connection shows no sign of a leak or movement.This is subject to certain limitations in the thickness of the wall of the tubo.Si wall is too heavy rings not be bitten, as when the wall of the tube is too thin, tube collapse rather than allow that rings to bite plenamente.Debería make reference to information from product manufacturers in all instances.Generally, the tube must have a hardness of not more than 80 degrees in the scale of Rockwell ' b '.

There are a number of manufacturers of this type of product in the world and usually contain the term 'LOK' in your product name.Large manufacturers this type of product that users not inter-change of different products.He is regarded as a sacrilege to mix parts of different producers.You must be reached, with the possible exception of the two manufacturers, all without exception are based on the original design.(The inventor of the same, then went to design two versions of the original design, the two exceptions mentioned above).Interchangeability in this product is really announced as a positive by some companies.Very often, these same companies offer part number cross reference in its product literature.

This product is used in many industries, including the following:

Petrochemical oil and gas production water hydraulics systems of high pressure NuclearOffshoreProductos farmacéuticosAlimentos and emissions bebidasNeumáticaCriogeniaControl paper

Accessories are produced in a wide range of styles with manufacturers offer tees, elbows, unions, male connectors, female connectors and many otros.Reductores of permit that installers resize tube from one to another, even from the metric to imperial.A difference of burning, connection is not any standard set for the manufacture of double Virola connections a.Sin nevertheless apply certain unwritten rules and all producers of used the same method to distinguish between the metric and fittings imperiales.Un step, or a shoulder is machined to the metric of body than the part of the hexagon and front-end nut connection. This is also evident in the literature of all manufacturers.
