Are Alloy 347 stainless steel Pipe Fittings magnetic?
Alloy 347 stainless steel pipe fittings are stabilized components that offer excellent intergranular corrosion resistance. The non-magnetic 347 stainless pipe fittings play an important role in connecting a range of piping equipment and influencing their flow characteristics. These fittings show enhanced resistance against carbide precipitation in temperatures ranging up to 1500 degrees F. They also show good creep rupture strength while possessing good low-temperature toughness. The alloy has outstanding mechanical properties and is stabilized due to the additions of columbium and tantalum. The 347 alloys can be employed alongside chloride and fluoride caustic solutions at moderate temperatures. These alloys show high resistance against polyphonic acid stress corrosion across hydrocarbon service systems.

What is the purpose of Stainless Steel 347 elbow in fitting?
Elbows are versatile fittings within the stainless steel 347 grade. These elbows influence the characteristics of the flow by redirecting the flow within the system. The elbows are usually designed in long or short radiuses. They are available in 22.5, 45, 90, 180 degree bends. The grade 347 elbows are strong and robust while securely sealing the line. If piping modules of dissimilar sizes have to be aligned in the system a reducing elbow is employed in connecting these components. The ends of elbows can be fitted to the subsequent module by butt welding, socketing or threading the components to the piping modules.

What is an ASTM A403 WP347 reducing tee?
A tee is a pipe fitting that is made of three openings shaped like a T. These openings are utilized in transporting fluids and gases across three different channels. ASTM A403 WP347 reducing tee has three ports of which one branch port is slightly smaller than the remaining ports in the run. These reducing tees are available in different configurations for various piping applications. The tees in this grade provide outstanding mechanical strength for various pumping applications. They are employed in ensuring a smooth flow pathway having no turbulence to the three connected piping components across the three ports connected on the run.

Does equivalent length of 347 Stainless Steel Pipe Fittings change with flow rate?
Equivalent length can be defined as the size of a fitting that would allow the rise of the same pressure drop as that of the fitting. A flow rate in a component can be determined as the volume of fluid or gases flowing across a said area. The ratios of the equivalent length of the Stainless Steel 347 Pipe Fittings are not constant. This opens the possibility of expecting errors of up to 30% in the equivalent length when there is turbulence seen in the laminar flow of the component. There are many pressures changes between connecting piping modules so, equivalent length changes depending on the flow rate.
