Stainless Steel 310S Pipe Fittings

Manufacturer Of ASTM A403 WP310S Buttweld Fittings, Elbow / Tee / Reducer in India

What are Stainless Steel 310S weld fittings?
Stainless steel 310S weld fittings are low carbon austenitic components. The fittings in this grade are employed to connect different piping modules and influence the characteristics of the flow. They can be used to curtail the flow, change its direction or join piping components of dissimilar sizes. Designed with a superior chemical composition of chromium and nickel, these weld fittings are robust and strong in various corrosive mediums. The lower carbon content in the 310s fittings allows them to be welded and fabricated with ease. These weld fittings are thereby less susceptible to embrittlement and sensitization while in service. Apart from this, they show good strength in temperatures up to 2100 degrees F.

What is the difference between Stainless Steel 310S welded and seamless fittings?
Welded and seamless fittings are the two most prominent methods used in producing components across the 310S stainless steel grade.

  • Stainless steel 310S welded fittings are designed by welding pieces of sheet metal in precise shapes and sizes. A seamless stainless steel 310S fitting is designed by cutting, heating, and shaping the fitting in precise dimensions.
  • Seamless fittings don’t have any welds or seams as seen on their counterpart.
  • Seamless fittings are robust and high-strength in comparison to standard welded fittings.
  • Seamless fittings can transport and suffice in 20% higher working pressure than welded  fittings.
  • Welded fittings are comparatively cheaper compared to seamless components.
  • Seamless fittings are restricted in size, while welded fittings have no such restrictions during their production. 

Should you weld ASTM A403 WP310S Pipe Fittings on both sides?
ASTM A403 WP310S pipe fittings are designed to be utilized in different pressure systems and require welding procedures as per the requirements. For socket weld fittings, only a single weld can be used, and the entire component can withstand different pressures and temperatures in small-sized pipes. In many cases, buttweld fittings are welded on both sides as they are utilized in connecting pipes of big sizes. When a fitting is double welded, the depths of each of the welds can vary. These double-welded fittings are high-strength components having the ability to withstand high pressures and temperatures.

 What is BW in 310S Stainless Steel elbow?  
BW is an abbreviation of buttweld stainless steel elbow. These elbows are versatile components and play a crucial role in, changing the direction of the flow and influencing the characteristics of the flow. These elbows are welded at the port to the pipe in the same plane. The robust modules are designed in different shapes and sizes, allowing them to withstand different pressure and temperatures setups. They can be availed as long or short radius elbows designed with 45, 90, 180-degree directions. The 310S buttweld stainless steel elbows can also be employed in joining piping components of dissimilar sizes in the piping system.
