The 316 stainless steel pipe has become an indispensable material for the industrial sector. This alloy of iron and chrome is recognized for its high resistance to corrosion, as well as its durability. 316 stainless steel tubing can be produced in both seamless and welded tubes to meet specific customer needs.

AL6XN is a superaustenitic stainless steel with outstanding resistance to chloride pitting, crevice corrosion and stress corrosion cracking. AL6XN is a 6 moly alloy that was developed for and is used in highly aggressive environments. It has high nickel (24%), molybdenum (6.3%), nitrogen and chromium contents that give it excellent resistance to chloride stress corrosion cracking, chloride pitting, and exceptional general corrosion resistance. AL6XN is primarily used for its improved pitting and crevice corrosion resistance in chlorides. It is a formable and weldable stainless steel.

ASME B36.19M is the standard specification for stainless steel pipes, which specifies the dimensions, tolerance, and manufacturing requirements for both welded and seamless pipes.

ASTM A312 TP316 is a standard specification for seamless, straight-seam welded, and heavily cold worked welded austenitic stainless steel pipes used in high-temperature and general corrosive service applications. The 316 Seamless Industrial Steel Pipe is made from a combination of chromium, nickel, and molybdenum, which gives SS 316 Seamless Tube excellent resistance to corrosion and rust.

UNS N08367 also commonly referred to as alloy AL6XN is a low carbon, high purity, nitrogen-bearing “super-austenitic” nickel-molybdenum alloy with excellent resistance to chloride pitting and crevice corrosion.

Good ductility and thermal conductivity Ideal for seawater applications.

Application requiring a combination of high strength and corrosion resistance may consider Incoloy 925 Weld Neck Flanges. All should be done to minimize work hardening of Incoloy 925 Socket Weld Flanges, but can be minimized by reducing the machining speeds and/or the depth of cut.

AL-6XN is a low carbon, nitrogen containing super austenitic stainless steel. The alloy is designed to be a seawater resistant material and has been found to resist a wide range of corrosive environments. Due to the alloy’s corrosion resistance and high strength, AL-6XN is a better choice than traditional duplex stainless alloys and more cost-effective nickel-based alloys.

Their types include eyebolts, structural bolts, square nuts, hex dome cap nuts, machine screws, studs, bolts, socket head cap screws and SS 321 hex cap screws. Pitting and crevice corrosion of grade 321 bolts can occur in chloride-containing environments, where stress corrosion cracking can occur above 60 degrees Celsius.

Sustained or prolonged exposure of Type 316L to 800-1500¡ãF (427-816¡ãC) may be harmful. In addition, stress relief between 100-1500¡ãF (593-816¡ãC) may cause this Type of slight embrittlement.

While both 304 and 316 stainless steels are strong, the addition of molybdenum to 316 gives it a slight advantage over 304 in strength. With 316 stainless steel, you can expect better resistance to chloride corrosion and pitting than 304 stainless steel, as well as higher strength at elevated temperatures.

Steel flanges provide an easy access for cleaning, inspection or modification. They usually come in round shapes but they can also come in square and rectangular forms. The flanges are joined to each other by bolting and joined to the piping system by welding or threading and are designed to the specific pressure ratings; 150lb, 300lb, 400lb, 600lb, 900lb, 1500lb and 2500lb.

A flange can be a plate for covering or closing the end of a pipe. This is called a blind flange. Thus, flanges are considered to be internal components which are used to support mechanical parts.

304 stainless steel does have one weakness: it is susceptible to corrosion from chloride solutions or saline environments such as the coast.

Stainless steel is an alloy of iron that is resistant to rusting. It contains at least 11% chromium and may contain elements such as carbon, other nonmetals and metals to obtain other desired properties. Stainless steel’s resistance to corrosion results from the chromium, which forms a passive film that can protect the material and self-heal in the presence of oxygen.
A stainless steel pipe system is the product of choice for carrying corrosive or sanitary fluids, slurries and gases, particularly where high pressures, high temperatures or corrosive environments are involved. As a result of the aesthetic properties of stainless steel, pipe is often use in architectural applications.

The 317L (00Cr19Ni13Mo3, UNS S31726) alloy is a molybdenum-based austenitic stainless steel. It is more resistant to chemical corrosion than conventional chromium-nickel austenitic stainless steels such as 304 alloy. In addition, compared with conventional stainless steel, 317L alloy has higher ductility, stress corrosion resistance, compressive strength and high temperature resistance. It is a low carbon grade or L grade, which is resistant to sensitization during welding and heat treatment.
Compared with 316L, 317L steel has good seawater resistance and SCC resistance, and is used in chemical ships, chemical products Reactor and other chemical equipment requiring high corrosion resistance.

The flange is second most used joining method after selding. Flanges are used when joints need dismantling. It provides flexibility for maintenance. Flange connects the pipe with various equipment and valves. Breakup flanges are added in the pipeline system if regular maintenance in required during plant operation.
A flanged joint is composed of three separate and independent although interrdlated components; the flanges, the gaskets, and the bolting; which are assembled by yet another influence, the fitter. Special controls are required in the selection and application of all there elements to attain a joint, which has acceptable leak tightness.
A flange is a protruded ridge, lip or rim, either external or internal, that serves to increase strength (as the flange of an iron beam such as an I-beam or a T-beam); for easy attachment/transfer of contact force with another object (as the flange on the end of a pipe, steam cylinder, etc., or on the lens mount of a camera); or for stabilizing and guiding the movements of a machine or its parts (as the inside flange of a rail car or tram wheel, which keep the wheels from running off the rails). The term “flange” is also used for a kind of tool used to form flanges.

There are classes 150 to 2500 and up to PN64 in this range of flanges. There are different types such as the SS UNS S30908 Orifice Flange, blind flanges, ring type joint flanges, raised face and flat face flanges.

The SMO 254 Spectacle Blind Flange Also- Resists Crushing In High Machine Fittings. Additionally, The 6mo Flanges Properties Includes Corrosion Resistance, Which Is Useful For Services In Corrosive Media Containing Environments.

Steel bars are one of the core components of any manufacturing
industry or for that matter any industry that relies on machineries.
Thanks to its versatile applications, steel bars find itself in the
epicenter of most of engineering industries, be it automotive, textile,
fabrication, construction, cement, ship building, paper and pulp,
defence, heavy earth moving equipments or aerospace.
The overwhelming popularity of steel bars is owed to the fact that
it is possible to be produced in varying types, shapes, sizes, and
grades of bars to cater the exact technical requirements. Steel
bars generally have the shapes such as flat, round, hexagonal,
square and channel and on most of the occasions, it is the shape
of the bar that defines its application area

Applications of Type 316 stainless are common in heat exchangers, manufacturing pharmacy and medicinal equipment, marine and coastal area engineering, and food preparation equipment.
