steel pipe unions

For industrial purposes, in pipeline systems, we usually need to change the direction of transmission; regulate the flow of fluids (oil and gas, water, mud); open or close pipelines, etc. Therefore, to accomplish these activities, steel pipe fittings will be applied.

For applications requiring greater resistance to stress rupture and creep, especially at temperatures above 1500¡ãF (816¡ãC), INCOLOY alloys 800H and 800HT are used.

Annealing is a heat treatment process mainly used to increase the ductility and reduce the hardness of the material. This change in hardness and ductility is the result of the reduction of dislocations in the crystal structure of the annealed material. Annealing is usually done after the material has undergone a hardening or cold working process to prevent its brittle failure or to make it easier to handle later.

These alloys possess superior ductility and excellent formability.

Solution treatment is the most common heat treatment method after stainless steel casting process. The carbide phase is completely or substantially dissolved after the austenitic stainless steel is heated to about 1100 ¡ãC .

NAS625 (NCF625, UNS N06625) is a nickel-chromium-molybdenum alloy with an additional of niobium. Matrix stiffening provided by molybdenum and niobium results in high strength. The alloy resists a wide range of severe corrosion environments. It also offers resistance to high temperatures. It also demonstrates remarkable protection against corrosion and oxidation. Its ability to withstand high stress and a wide range of temperatures, both in and out of water, as well as being able to resist corrosion while being exposed to highly acidic environments makes it a fitting choice for nuclear and marine applications.

Forged Pipe Fittings (Socket Weld and Threaded) are made in
accordance to ASME B16.11, MSS-SP-79/ 83/ 95/ 97 and BS3799
standards, and are used to connect nominal bore schedule pipes
and pipelines.

Alloy 625 (UNS N06625) is a nickel-chromium-molybdenum alloy with an addition of niobium.

Alloy 600 is machinable in both hot and annealed conditions. Due to the large amount of heat generated when machining this alloy, high-speed steel, cast non-ferrous or carbide tools should be used.

The alloy exhibits excellent resistance to seawater and brine, making it well suited to marine applications.

These alloys can suffice in high pressures and extreme temperatures.

A pipe fitting, for pipe or pipe, is a very short piece of pipe or pipe with a socket or female pipe thread on one or both ends that allows two pipes or tubes of the same or different sizes to be joined together.

In addition to being reliable, it has a high tolerance capacity. Our Stainless Steel 304 Forged Fittings are produced using modern technology and high-quality raw materials that assure compliance with international standards.

A105 shall adhere to tensile strength, yield strength, elongation, reduction of area, and hardness requirements. Guidelines for retreatment, repair by welding, and product marking are given.

Our high quality standard pattern 150 lb rated stainless steel threaded pipe fittings are manufactured to the highest standards. All stainless steel pipe fittings are monitored by quality control personnel for strict compliance with applicable standards & specifications.

INCOLOY alloy 800 is used in a variety of applications involving exposure to corrosive environments and high temperatures.

Stainless steel 304 welded outlets can become very brittle at long-term temperatures of 1200¡ãF to 1500¡ãF. Also for machinability of stainless steel 304 socket weld outlets, high speed turning and cooling tools are recommended. The range of stainless steel 304 threaded outlets shown is made up by utilizing high grade machinery and modern methods to pass many strength limitations.

Threadolet is a type of self-reinforced branch fitting developed by a Company called Bonney Forge. It is used whenever threaded branch connections are required from the pipe header. Mostly, it is used for small size piping with a low-pressure application.

A182 F91 Wrought alloy steel tubes, flanges, wrought fittings and valves and other components for high temperature use.

Stainless steel tee fittings are tee fittings. It has two 90¡ã angled outlets and one inlet. These fittings may have threads on the ends. These accessories are used in several industries such as oil refining, water treatment and other treatment units. Tee fittings are available in different sizes and shapes, including straight tees, equal tees, reducing tees, Y tees, transverse tees, male and female branch tees, and male and female tees.

Flanges, fittings, valves and various other parts ordered to customer dimension or to industry standards such as MSS, ASME and API specification are included in the scope.

The inclusion of chromium in combination with nickel in its chemistry makes it resilient to chemical and environmental corrosion.

Stainless Steel 316 is a molybdenum austenitic alloy that is highly resistant to corrosive and chloride environments. Typically, this grade of stainless steel is used in exhaust manifolds, heat exchangers, jet engines and many other applications.

Hence, materials with low carbon content such as ASTM A105 Fittings are not recommended to be used in those applications which have the need to be constantly exposed to a range temperatures above this value.

ASTM A105 is an iron-carbon alloy with carbon content of 0.0218%~2.11%. Also called carbon steel.

HT PIPE is a well-known company that is a pioneer in the production, distribution and export of industrial products such as nickel alloy pacifiers and has made significant progress in the industry.

Cupro Nickel Forged forgings are annealed at temperatures between 593 and 816 degrees Celsius (1100 and 1500 degrees Fahrenheit). Copper-nickel forged threaded crosses are still widely used in modern shipbuilding.

During the aging process, Monel K500 butt welded pipe fittings experience a slight permanent reduction, but a slight warpage occurs due to the entanglement of low heat and slow cooling rates.

A105 is American ASTM standard number,¡±A¡± stands for common carbon structural steel.ASTM A105 is the most common carbon steel material under ASME/ANSI/API/MSS standard.It¡¯s standard specification for carbon steel forgings for piping applications.

For instance, the use of Carbon Steel ASTM A105 Fittings is prominent in those applications that involved not only environments where the temperatures are high, but also in those applications at room temperature.

Alloy 625 (UNS N06625) is available in Round Bar, Flat Bar, Extruded section, Pipe, Tube, Plate, Sheet, Strip, Plate, Hexagon, Forging Stock, Extruded Section, Wire and Powder.
