Get to know about Tube Fitting

SMO 254 Tube fittings offer leakage-free connections and suitable for power and instrumentation applications. Besides, these are the products available in high-quality standards and varied sizes and configurations. These tube fittings are useful in various instrumentations, process control units, and chemical plants. Also, SMO 254 tube fittings work well in power generation plants, pulp industry and petroleum plants. Additionally, SMO 254 Tube fittings are useful in special applications requiring high pressure carrying capacity. 

Features of SMO 254 Tube fittings 

These are the products that work well in halide solutions and the presence of chloride and bromide ions. The SMO 254 grade shows the effect of local corrosion due to pitting, crevice, and stress. SMO 254 is a material with a low carbon element. Such low carbon holds less risk of carbide precipitation during heat application during welding activity. 

Installation of SMO 254 Tube fittings 

These SMO 254 tube fittings are easy to install and do not require additional torque. During initial installation, the gas inspection gauge ensures sufficient pull-up.

Inconel is nickel-based material shows a high nickel-chromium content. These components are known for their extreme heat tolerance capacity. Here, Inconel 625 is a material also known as UNS N06625 alloy or Inconel tubing material. INCONEL 625 TUBE FITTINGS are the product with a high degree of tensile strength and ability to work at high-temperature ranges where other metals burn or melts. Here, these parts are heated at their melting point to fuse them. INCONEL 625 TUBE FITTINGS are famous for temperature resistance ability, and hence welding of Inconel material is slightly tricky or impossible. 

Things to remember

Following are the various things need to consider while performing welding of INCONEL 625 TUBE FITTINGS:

1. Weld Inconel 625 using Tungsten Inert Gas (TIG)

Inconel 625 grade has the too high melting point, and it becomes difficult to join two different Inconel workpieces if they are large. The joining of Inconel 625 grade through the welding process. A welding process combines Inconel pieces at high temperatures using a filler material. It is the best method to perform welding of Inconel alloys. Also, several experienced welding professionals suggest the TIG welding procedure. It is the process that uses a filler material. Further, the electrical arc welding process does not require a filler material. Hence, it is most suggested for Inconel welding due to its ability to combine two alloy pieces without enabling its cracking.

2. Use Inconel 625 for filler material

For obtaining the best results from Inconel welding, it is essential to use Inconel 625 filler metal.  Here, the filler metal is one of the most straightforward Inconel alloys suitable for welding two Inconel portions. More comfortable melting point is the reason for choosing Inconel 625 in place of several other elements. When the two joining components differ from one another, then it can cause a problem. There might be a chance of bimetallic corrosion or thermal expansion after exposing them to high temperature in such cases. For welding of INCONEL 625 TUBE FITTING, alloy one can use Inconel welding filler material.

3. Use an automated machine to perform welding of Inconel 625

For the accomplishment of welding manually, an inconsistent process is best suited. Here, the initial few welds might be inadequate as the welder reaches the groove. But the next few welds are the best, and then welder needs to produce rest of the welds with the same motion. Here, he or she may suffer fatigue due to repeated movements over and over. The same thing may happen with the person holding a boiling welding device that is partially melting a super heat-resistant metal, and then it may invite disaster.

Duplex is a material that offers high resistance against stress corrosion and cracking. Duplex tube fittings are suitable to work in the chloride-containing environment. Also, super duplex grade offers the ability to work in the presence of hydrogen sulfide. The duplex grade has high mechanical strength and capacity to work at high-temperature range. Duplex tube fittings show good fatigue and mechanical strength as it has physical properties as well. Here, duplex alloy offers the good working ability, weldability and formability features. The material grades are designed and developed for heavy load engineering operations due to its strength. 

For the production of the tube, fittings require high-end manufacturing procedures and high-quality raw materials. Tube fittings are available in precise dimensions and tolerance capacity. The stainless steel is processed for quenching, tempering, and other procedures. Also, tube fittings go through various procedures, including finishing, matte finish, sand brushing, etc. 

Duplex tube fittings 

Here, in Duplex tube fittings, duplex type of stainless steel is used, which has the mixture of ferrite and austenite microstructure. Duplex tube fittings consist of 50-50 concentration of elements. The duplex grade is commercially available material contains a 60/40 ratio. These tube fittings show improved strength due to austenitic stainless steel grade. Besides, duplex tube fittings show enhanced resistance to corrosion, pitting, crevice and stress conditions. Duplex tube fittings show the presence of 19 to 20% chromium, 5 % molybdenum and a lower concentration of nickel. These elements are present in less amount compared to austenitic stainless steel. The duplex tube fittings are a product with double mechanical properties and resistance to cracking. Also, these tube fittings are malleable and brittleness at 50-degree C. 

Super duplex tube fittings

Stainless steel 2507 is a material grade that contains 22% chromium, 5% nickel, 25% chromium, and 7% nickel. The material grade is known as the super duplex due to its high resistance capacity. Besides, super duplex tube fittings show better stress and corrosion due to its mechanical properties. Super duplex tube fittings consist of elements like iron, chromium, nickel along with molybdenum. These tube fittings of super duplex show good resistance to stress and corrosion. Besides, it can hoist in conventional grades. Super duplex tube fittings are ideal for offshore and onshore applications due to high resistance.
