Steel fittings

Steel fittings

In water, oil and gas transmission lines, different steel connections are used, which are different depending on the type of transmission line, pressure, temperature, and transmission materials used. Also, the development of technology and changing needs in different industries have led to the creation of new and more diverse connections that may be used according to the specific needs of each project. Therefore, in choosing fittings for liquid and gas transmission lines, it is necessary to carefully pay attention to the specific conditions and needs of each project.

Types of steel fittings and applications in industries

Steel fittings vary depending on the type of transmission line, pressure, temperature, and transmission materials used.

  • Welded Connections: This type of connection includes the welding of pipes to each other or to other parts. Welded joints are usually used for transmission lines with high pressure and temperature, such as gas and oil lines. These connections include circular welds (tube-shaped), straight welds (T-shaped or Y-shaped) and binary welds (X-shaped).
  • Threaded Connections: This type of connection includes threads and internal and external threads that are created on pipes and metal parts. These types of connections are used for smaller lines and lower pressure such as water lines and household plumbing
  • Flanged Connections: This type of connection consists of two flange pieces that are connected to each other and connected to each other using bolts and nuts. These types of connections are used to connect pipes to equipment such as valves, pumps, and fluid transfer equipment, and are especially used in lines that require replacement and maintenance.
  • Seamless Connections: This type of seamless connections are produced without seams using a special production process such as cold working process or injection of molten materials into the steel matrix. This type of connection is used for lines with high pressure and temperature that require more performance and stability.
  • Nipple Connections: This type of connection includes nipples or short pieces of steel that are typically used to connect pipes to each other or to other equipment. These types of connections are used in water, gas and industrial systems.
  • Bracket Connections: These types of connections include brackets or carriers that are used to maintain and support pipes in transmission systems. Brackets are typically attached to walls, columns, or other structures and fix the pipes in place.
  • Flexible Connections: These types of connections are used when there is a need to move and absorb shrinkage and changes in temperature and pressure in transmission lines. These fittings are made of flexible materials such as flexible metal pipes or pressure reducing materials such as rubber.
  • Quick Connections: These types of connections are typically used in systems that require quick and easy replacement of pipes or equipment. These connectors are usually designed as quick locks or quick connectors that can be replaced quickly and with the least possible time.
  • Socket Connections: This type of connection includes sockets and drains, where the pipes are inserted as a solution and are secured using soluble or adhesive materials or welding. These types of connections are used for water lines, sewage and sewerage.
  • Swivel Connections: This type of connection allows the pipe or metal piece to rotate around its axis, which can be useful in cases where there is a need to move and rotate pipes and equipment.

Types of steel flanges

Types of steel flanges

Flanges are one of the main components of industrial connections and are used to connect pipes or equipment to each other. These act as an interface between pipes and equipment or other parts of piping systems. Depending on different needs and conditions, there are different types of flanges.

  • Weld Neck Flange:- These flanges have a long neck that is welded to the ends of the pipe. This type of flange has high resistance to pressure and temperature, it is suitable.
  • Types of steel flangesSlip On Flange: - In this type of flange, it has two flat edges to which the pipe is connected. These flanges are suitable for lower pressure and temperature applications
  • Conical flange (Socket Weld Flange): - These flanges have a special socket in which the pipe is placed and then they are fastened together by welding.
  • Blind Flange: These flanges are used to close or block the end of a pipe or system. They have a glossy screen without holes.
  • Threaded Flange: This type of flange has internal and external threads that are connected to pipes or other components using bolts and nuts.
  • Double Weld Flange: These flanges have two flat edges, the pipe is connected to both sides and then it is connected to the edges of the flange by welding.
