304 tees with elbow and reducers

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.

Inconel is a superalloy made of high concentrations of nickel, chromium and molybdenum. Inconel 625 is highly resistant to corrosive and oxidizing media in a variety of environments. These alloys have excellent ductility and excellent formability. They can be welded easily and are resistant to post-weld carburization or graining.

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.

The butt welded tees can maintain a straight flow or reducing flow which depends on the ordered pipeline system. The reducing branches (reducing tees) make a perpendicular connection with the mainline. The radiuses of the tees are usually smaller than the main flow line. The radiuses of the straight tees are produced in a way that has similar radiuses with the main flow line.

Alloy X is known for its excellent high temperature strength and can withstand temperatures up to 2200¡ãF. The alloy can also be easily fabricated by manual and automated methods with forming and welding properties. In addition, Hastelloy X is resistant to corrosion, heat and oxidation and can withstand reducing or neutral atmospheres and oxidation.

UNS S31254 is often referred to as a ¡°6% Moly¡± grade due to the molybdenum content.

Alloy 625 / Inconel 625 is used for its high strength, excellent fabricability (including joining), and outstanding corrosion resistance.

It can be easily welded and processed by standard shop fabrication practices.

This grade has surpassed its original intent and overlapped into many industries proving useful owing to its high level of molybdenum amount other elements, which allows 31254 to be used successfully in various applications such as Flue gas desulfurization and Chemical environments.

The alloy also resists ammonia bearing atmospheres, as well as nitrogen and carburizing gases.

The following procedure after the marking is the cutting step. The way of cutting differs for various materials. Thus, for carbon steels, the flame cutting method is utilized. Moreover, stainless steel components can be cut using a plasma arc cutting machine. If the plasma arc cutter is used some certain conditions must be maintained.

Hastelloy c-22 and c-276 are the only materials resistant to corrosion in wet chlorine, hypochlorite, and chlorine dioxide solutions, with significant resistance to high chloride solutions such as ferric and cupric chlorides. Corrosion resistance.

We manufacture piping products as well. When customers need different elements be fitted together before installation, the application of fabricated elements together is called the piping spool applications. There are Stainless Steel Pipe Spools products as well other material made spools in used.

HASTELLOY C276 is not prone to grain boundary precipitation in the as welded condition and therefore suitable for many chemical process applications.

Environments that don¡¯t attack 304/304L stainless steel will normally not corrode 317L.

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.

Inconel 718 is a nickel-based superalloy ideal for applications requiring high strength in the temperature range from cryogenic to 1400¡ãF. Inconel 718 also has excellent tensile and impact strength.

Blind flanges are the final division of the flange classification. They are used as end-closers for the pipes valves or pumps. Since blind flanges are used as obstacles against the fluid flow, they are the highest stressed parts of the flange systems.

At elevated temperatures the annealed and solution annealed alloy shows good resistance to scaling and has high strength.

Hastelloy B2 prevents the formation of grain boundary carbide precipitates in the weld heat affected zone, making it suitable for most chemical process applications in the as-welded condition. The heat affected weld zone reduces the precipitation of carbides and other phases to ensure uniform corrosion resistance.
Alloy B2 also has excellent resistance to pitting and stress corrosion cracking.

Pipe Spools are fabricated from a number of raw pipes and pipe fittings (e.g. elbows, flanges, tees, etc.) in fabrication shops.

A nickel alloy of this type also has great resistance to hydrochloric acid at different concentrations and temperatures.

The cylindrical bulge eases the use of flange in extreme conditions such as; elevated temperatures or high pressurized atmospheres. These flanges are welded to pipes or fittings by using butt-welding which enables a total fixation of the body. Slip-on flanges are also very common in use because of their low cost. They do not require excessive surface finishing as weld necked flanges.

Prefabricated steel s take advantage of offsite prefabrication to improve the speed or erection and cost predictability of the solution.

The joint is created by bolting two flanges to each other and sealing them by using various gaskets. Flanges are usually made of aluminum, bronze, brass or carbon steel. The most preferred material for general flange applications is the forged carbon steel. Moreover, flanges can be layered internally with different types of linings. Usually, flange material is selected as the same material with the pipe material. This material selection is conducted in order to prevent possible galvanic corrosion risks. The proper material selection for flanges is decided according to ASTM A-182 standards.

MONEL 400 solid solution alloy can be hardened by cold work, but can be hot worked or cold worked, then annealed into complex structures and welded using an appropriate welding process.

316 can be annealed to resist weld decay.

For certain applications, grade 254 SMO has been reported to be a cost-effective substitute for high nickel and titanium alloys.

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.
