ASTM A312 304L Stainless Steel Seamless Pipe with Flange

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.

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.

Thermal processing equipment in industrial applications, such as baskets, trays, and fixtures. In chemical or petrochemical processing it is used for heat exchangers and piping systems in nitric acid media, especially where resistance to chloride stress corrosion cracking is required.

Process equipment used in the production of chlorinated and fluorinated hydrocarbons.

The durability of steel is one of the best advantages of the pipeline systems. It is strong and it can withstand the pressures, temperatures, heavy shocks, and vibrations. It also has unique flexibility which provides an easy extension.

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.

AL6XN is primarily used for its improved pitting and crevice corrosion resistance in chlorides. It is a formable and weldable stainless steel.

Resistance to chloride ion corrosion is one of the main factors that facilitate the use of incoloy grades in different industrial applications.

INCONEL 718 alloy was primarily chosen by design engineers for its high strength in extreme temperature conditions at both ends of the spectrum. It can be used from low temperatures all the way up to 1300¡ãF/704¡ãC. It exhibits extremely high yield, tensile and creep rupture properties across the entire range. It also exhibits excellent tensile and impact strength.

Built-up sections are produced at the factory and is then transported to the original site and assembled. This concept is generally used to build Metro stations, industrial units, warehouses, etc.

The addition of copper to this grade gives it better corrosion resistance than conventional chromium-nickel stainless steels, especially against sulfuric, phosphoric and acetic acids. However, the use of hydrochloric acid is limited.

The alloy has good oxidation resistance and creep strength to 1500¡ãF (816¡ãC). It also possesses good low temperature toughness.

MONEL K-500 alloy has corrosion resistance comparable to 400, but has higher mechanical strength and hardness. Has good thermal corrosion resistance and long-term tissue stability. It is mainly used in the manufacture of turbine blades and gas turbine blades with a working temperature below 750¡ãC on aero-engines, and in the manufacture of fasteners and springs on ships; pumps and valve parts on chemical equipment, and scraping on paper-making equipment. Blades etc.

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

This nickel steel alloy has good resistance to heat affected and knife-line zone attack. This alloy also bears the brunt of formic, sulfuric, phosphoric, acetic acids and various other non-oxidizing media.

The strength of this nickel steel alloy is maintained to 1200¡ã F but stays ductile and tough down to temperatures of 400¡ã F. Its melting range is 2400-2460¡ã F.

Hastelloy is a corrosion-resistant nickel alloy that contains other chemical elements such as chromium and molybdenum. This material has high temperature resistance and excellent corrosion resistance. Hastelloy C276 is one of the Hastelloy grades used in the oil and gas industry.

Alloy 254 SMO is a high end, molybdenum and nitrogen alloyed super austenitic stainless steel with low carbon content.

Pipe spool fabrication is very important because the construction of the ship and other marine industries require intensive piping. Pipe spools create great advantages because they reduce the limitations of space on site.

The lap-joint flanges have the nearly same shape as the socket weld flanges except for the weld gap. Thus, their use in applications that can cause corrosion is advantageous. Another flange type is the threaded flanges. The threaded flanges are very useful in specific applications since they do not require welding for fixation.

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

Inconel 625 material has excellent strength and hardness. They have a minimum tensile strength of 120Ksi and a minimum yield strength of 60ksi. In addition to that, they can easily be stretched up to 30% and still have excellent workability.

316L is very similar to 316 in almost every way.?

These have the advantage of nickel and molybdenum providing resistance against the most reducing environments. The oxidation resistance is also high in these materials due to the addition of the chromium content.

304 stainless steel is the most common form of stainless steel in the world due to its excellent corrosion resistance and value. It contains 16% to 24% chromium and up to 35% nickel, as well as small amounts of carbon and manganese.

HASTELLOY C276 is one of the few alloys resistant to wet chloride gas, hypochlorite and chlorine dioxide solutions.

Pipe spool systems are mostly used in power plants and petroleum refineries which requiring intensive piping. These systems include carriage and transport of fluid and gas and these transportation systems need lots of connection parts. In these systems, there is no place for mistakes.

Monel 400 is used in process vessels, heat exchanger piping, and gasoline and potable water storage tanks in the marine sector. The non-sparking properties of this alloy make it suitable for high-risk situations in the explosives industry, rockets and pulp and paper industries.

The plasma arc cutter is utilized for large pipes (above 28 inches of nominal pipe size) and its use is also beneficial for cutting off branches. If possible, an internal case must be located into pipes or fittings, in order to protect them from the spatters which are created by the plasma arc cutter. After the cutting, and edge preparation must be maintained.

The surface edges of the components must be even and the surface impurities must be removed. A beveling process is implemented for the edges of the parts. A grinding machine is employed for the beveling process. The type of grinding machines for beveling differs for stainless steel components and carbon steel components.
