304 pipes with flanges butt weld tee and elbows

304 Piping Spools are made of 304 Stainless Steel, a common and popular material in many industrial applications that require resistance to corrosion and oxidation. These S30400 Piping Spools are prefabricated using specialized machinery and processes, which ensure that they are highly accurate and reliable.

MONEL K500 is a age-hardenable Nickel-Copper alloy which combines the corrosion resistance of Alloy 400 with high strength corrosion fatigue and erosion resistance.

Therefore the selected radius of the elbow can be very important. The other type of elbows is reducing elbows. In this type of elbows, the dimension of the center-line radius equals to the half of the nominal size of the larger end. Reducing elbows, again, maintain a 90¡ã flow change in the pipeline system. Moreover, a 180¡ãflow change can also be maintained by using a specific type of reducing elbow that is called ¡®return bends.

C276 is forged between 2250/1750oF (1230/955oC) and then soaked at the forging temperature for 30 minutes per inch of billet or ingot section thickness. Forging should begin immediately, the billet is removed from the reheat furnace, a 25/40% reduction helps retain as much internal heat as possible. For optimum corrosion resistance, forged parts should be subsequently annealed. See Heat Treatment.

Hastelloy B3 suppliers and Hastelloy B3 manufacturers can be reached out to all over the country.

Alloy 600 / Inconel 600 is a combination of nickel chromium and iron that provides the standard material for the chemical industry and the automotive engine, aero engine and airframe sectors. Controlled chemical composition is restricted for use in the nuclear industry to eliminate the risk of stress corrosion cracking in high-purity water containing chloride ions.

Alloy C-276 is also defined as Alloy C276, Inconel C 276 or Hastelloy C, which is a superalloy with a perfect combination of molybdenum, nickel and chromium. Tungsten is added, which is designed to provide excellent corrosion resistance even in harsh environments.

This alloy is resistant to the formation of grain boundary precipitates in the weld heat-affected zone, thus making it suitable for most chemical process applications in an as welded condition.

Alloy 400 is a solid solution alloy that can only be hardened by cold working.

The number of welds on a spool must be kept in a minimum count. The dimension of the spacing between circumferential welds and the center lines must not be larger than the four times the wall thickness of the pipe or fitting. After the main welds, tacks welds must be done precisely. All welds in the spools must be implemented according to proper Welding Procedure Specification (WPS). After the welding process is done, quality control of the components is performed by the specialists.

A low corrosion rate in rapidly flowing brackish or seawater combined with excellent resistance to stress-corrosion cracking in most freshwaters, and its resistance to a variety of corrosive conditions led to its wide use in marine applications and other non-oxidizing chloride solutions.

Inconel 718 has become useful in a wide range of applications ranging from manufacturing operations to military equipment and the aerospace industry.

316 can be annealed to resist weld decay.

It is used for components that require exposure to sea water and high mechanical stress.

AL6XN has greater tensile strength than common austentitic stainlesses, while retaining high ductility and impact strength.

In pressurized water reactors it is used for control rod guide tubes and steam generator baffle plates etc. Furnace retort seals, fans and fixtures.

The socket welded tees are manufactured due to the ASTM ASME B16.11 standards. These standards optimize and decide the proper pressure and temperature ratings, radiuses and required material for the production of the tees. Furthermore, the B16.11 standards are only allowable for carbon and alloy steels. The socket welded tees can be produced into three pressure categories which are; Class 3000, Class 6000 and Class 9000.

625 has outstanding resistance to pitting, crevice corrosion and intercrystalline corrosion.

When selecting stainless steels that must withstand corrosive environments, austenitic stainless steels are often used.

HASTELLOY C276 is a Nickel-chromium-molybdenum wrought alloy that is considered the most versatile corrosion resistant alloy available.

They have good creep and oxidation resistance. Strengthening of super alloys is performed by solid-solution hardening, work hardening, and precipitation hardening methods.

904L grade stainless steel is unlike any other steel. Due to its extra amounts of chromium, molybdenum, nickel and copper, 904L steel features superior resistance to corrosion, rust and acids.

Other popular nickel-chromium alloys are age hardened through the addition of aluminum and titanium.

ASTM A403 Pipe Spools, SS Pipe Spools,Stainless Steel Pipe Spools, WP Grade SS 304 Pipe Spools, DIN2617 SS Pipe Spool, DIN2616 SS Pipe Spool in China.

The two most common stainless steel grades are 304 and 316. The main difference is the addition of molybdenum, an alloy that significantly improves corrosion resistance, especially in environments with more salt or chloride exposure.

316 stainless steel has more carbon in it than 316L. This is easy to remember, as the L stands for “low.”

Pipe spools are pre-shaped to make easier assemble using hoists, gauges and other tools for joining the parts. Pipe spools unite long pipes with flanges from the end of the long pipes so they can be bolted with each other with matching flanges.

Little or no attack occurs at room and elevated temperatures in dry gases, such as chlorine or hydrogen chloride. At temperatures up to 550C in these media, this alloy has been shown to be one of the most resistant of the common alloys.

As a beginning of the manufacturing, all components must be marked in order to increase the monitorability of the materials. The marking work can be implemented due to the respective number of components. Moreover, all dimensions of the pipe spools must be marked on to themselves. The traces on the components must not contaminate the material otherwise traces can react with the material and this may cause deleterious problems.
