Petrochemical valves

Used to regulate fluid flow. If the flow enters from the side, the petrochemical valves will not function properly. The flow in gate petrochemical valves or gate valves, unlike single-seat sliding valves, can be from both sides. These petrochemical valves are used to transfer liquid and gas hydrocarbons. The most important advantages of butterfly petrochemical valves are their small volume and rotational movement of the handle (up to 90 degrees). Also, due to the design of petrochemical valves, fluid is not trapped in them. Butterfly petrochemical valves are produced in all sizes and with different materials. Application of petrochemical valves in vacuum systems and transfer of liquid fluids and powders.

Advantages of flange connection method

The most important reason for using this method is its detachability (Removable), which means that if you weld two pipes directly to each other, if you want to separate them, you have to cut and weld again, but in If you use flanges, you can do this by opening and closing the bolts.

Usage of flanges in industry and installations

Connecting pipes to equipment such as pressure vessels, pumps, compressors, etc.

Change of material in the pipe.

Connection to valves and other items in the pipeline route that may require repairs.

Flat surface flange (FLAT FACE) (FF)

In these flanges, when the connection is made, the surface of the two flanges used must be smooth. Its main use is when we use two flanges for the system or water connections that are made by casting.

What is a flange?

Flanges are steel parts that are used to make a connection and can connect the pipe to other piping items such as vibrators, valves, etc. Various methods for connecting the pipe and its items to each other or to existing equipment Such as welding and…, one of which is flange fittings.

Male & Female Flange (M&F)

This flange must be made in pairs. The surface of one of the flanges has a protrusion and the other surface has a recess, which is designed according to the position used.

The surface of the material usually has “16/3 depth of recess and the surface of the material has” 1/4 protrusion.

Welding Neck Flange

This type of flange has a tapered neck, the radius of which is equal to the diameter of the pipe at the end of the flange path. It is known that it is welded and connected to the pipe at the end, which is the main reason for increasing the flange bearing. The flange is at high pressures and sub-zero temperatures, which is also suitable for use when it has vibrating and oscillating loads.
