Because the supplementary string is held in place by the Packer and Tubing Hanger from the bottom up, the temperature of the string tube will be neutralized by the movement of the cylinder and piston in the event of a change in temperature and consequently a change in the length of the string. A sliding pipe is a cylinder and swage pipe fitting piston pipe, which is called a Stroke sliding pipe. The sliding pipe is placed in the semi-open position inside the supplementary string
What is a swage pipe fitting?
Metal fittings are used to make connections between metal pipes and other piping items, including welded flanges, cast iron valves, brass valves, rubber vibrators, accordion vibrators, etc. Metal fittings are divided into several general categories according to the type of arrangement of its edges for connection and made alloy:
Manisman Fittings: These types of metal fittings are welded together and used with Manisman and seamless pipes, as well as their alloy according to ASTM A234 WPB standard and its standard dimensions according to ASME B16.9, which is in the manufacturing process. They do not use any weld seams. Manisman fittings are suitable for high temperature and pressure systems. Manisman connections are available in a variety of thicknesses, including Manisman Class 40, SGP and STD connections on the Pipe Kala website.
Sealed black fittings: Like Manismann fittings, this type of metal fittings is used as a weld and differs from Manismann fittings in the manufacturing process. These fittings are made using the mold method and with weld seam in their body, which has a lower pressure and temperature tolerance limit than Manisman fittings.
Metal fittings are widely used in the oil and gas industry and building facilities and are used to connect pipes and valves to each other. Metal fittings are used in accordance with the operating pressure of the system and the type of pipes and valves. The most important metal fittings are: seamless black fittings (Manisman), seamed black Pipe Nipples and Swages fittings, galvanized gear fittings, black gear fittings, high gear compression fittings, silent volt high pressure fittings. Connections are divided into 3 categories based on how they are connected:
- Types of metal fittings
- Buttweld fittings
- Socket weld connections
- Threaded Fittings
- Standard metal fittings
Buttweld welding joints are made according to ASME B16.9 dimensional and weight standards and silent and threaded joints are made according to ASME B16.11 standard. The alloying standard of metal fittings is based on ASTM A403, A234, A420.
Domestic demand for swage pipe fitting
Fittings or fittings are parts that are used to connect pipes to each other, change the direction of the pipe, branch swage fitting off or change the diameter of the pipe.
Ties or fittings are made in two types of screws (ribs) and welds, which should be used exclusively in hot and cold water piping and white return. White or non-galvanized ribbed patches are difficult to use. It causes the pipes to rot and corrode.
