316 stainless steel has more carbon in it than 316L. This is easy to remember, as the L stands for “low.”
316L is very similar to 316 in almost every way.?
316L, however, is a better choice for a project that requires a lot of welding because 316 is more susceptible to weld decay than 316L (corrosion within the weld).
316 can be annealed to resist weld decay.
316L also is a great stainless steel for high-temperature, high-corrosion uses, which is why it’s so popular for use in construction and marine projects.
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.
Alloy 347 (UNS S34700) is columbium stabilized austenitic stainless steel plate with good general corrosion resistance and somewhat better resistance in strong oxidizing conditions than 321 (UNS S32100).
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.
It has excellent resistance to intergranular corrosion after exposure to temperatures in the chromium carbide precipitation range of 800 ¨C 1500¡ãF (427 ¨C 816¡ãC).?
Stainless steel 904L / 1.4539 material can be used to make hot and cold rolled sheet and strip, semi-finished products, bars, rolled wire and profiles, as well as seamless and welded pipes for pressure applications.
The alloy has good oxidation resistance and creep strength to 1500¡ãF (816¡ãC). It also possesses good low temperature toughness.
Alloy 904L outperforms other austenitic stainless steels due to the higher degree of alloying of nickel and molybdenum.
Alloy 347H (UNS S3409) stainless steel plate is the higher carbon (0.04 ¨C 0.10) version of the alloy.
The high chromium content promotes and maintains a passive film that protects the material in many corrosive environments.
When selecting stainless steels that must withstand corrosive environments, austenitic stainless steels are often used.
The high amounts of nickel and chromium in austenitic stainless steels provide excellent mechanical properties, as well as excellent corrosion resistance.
Grade 304 stainless steel is generally considered the most common austenitic stainless steel.
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.
Raw pipes are cut to the required sizes and moved with pipe fittings to a fitting table, where some of the components are fitted together (i.e. temporarily connected). The resulting sub-assembly (part of the final pipe spool) continues with welding operations (i.e. permanent connected) before it comes back to the fitting table and gets fitted with other spool components.
Steel Pipe Spools are also referred as prefabricated components of a piping system such as pipes, flanges and pipe fittings, and they are mounted during the development before sending them to the manufacture.
This Stainless Steel Pipe Spooling are often flanged to facilitate the connection to other spools and also mostly preferred in various industrial applications such as power plants and petroleum refineries require intensive piping.
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.
The pipe spools are usually applied in concrete structures to make sure the necessary fittings are in place before pouring concrete into the construction.
The Stainless Steel Fabricated Pipe Spools are useful for the customers in that they do not miss any parts and they eliminate the difficulty of onsite installation.
There are different material grades used to produce these spools. The 304 stainless steel is the most used grade. The Sanitary Stainless steel 304 Tri Clamp Spool is made up of this material and has 3 clamps fitted for convenience of the customer. We also provide custom solutions to our customers. Please contact us for your needs.
Pipe Spools are fabricated from a number of raw pipes and pipe fittings (e.g. elbows, flanges, tees, etc.) in fabrication shops.
The combined parts are heat treated with the aim of reducing the induced inner stresses. The heat treatment procedure is performed according to ASME B31.3 standards. Thereafter, the pipe spools must be painted for protection of the surfaces from any corrosion risk.
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.
Pipe spools are the pre-build parts of a piping system. Pipes, flanges, and fittings are called pipe spools and they are produced before they are used in the piping system.
