Stainless Pipe for Boiler, Super Heater and Heat-exchanger

Walmi is a manufacturer of stainless pipe for Boiler, Super Heater and Heat-exchanger Tube,U/U-bending/U-bends/U-type tube as per ASTM A213 with materials of 304, 304H, 321, 321H and 316L. Stress relieved and Hydrostatic testing after U-Bending are all available in our factory.

Sizes range from 12.7mm to 38 mm ( NPS 1/4”- DN8 to NPS 1 1/4”- DN32) outside diameter with a full tubes schedules ranging from sch10S through double extra heavy.

The stainless pipe and U tubes are delivered in fixed lengths. What’s more, Walmi can supply stainless pipe exceeding 35m long before U-bending. All tubes can be cut to customer’s exact requirements. requirements.

Application

Walmi Stainless Steel U Tubes,Boiler, Super heater and Heat Exchanger Tube are austenitic stainless tubes, including grades containing the letter H, which can provide higher creep-rupture strength.

Advantages

Stainless Steel Hollow Bar is primarily used for the manufacture of radially machined components, a great variety of hollow products and cylindrical components, which will be used in conditions where where corrosion is an issue .The use of Hollow Bar is an economic and efficient means of supplying high quality raw material and a sensible alternative to the use of solid bar as it reduces machining requirements and minimizes material wastage.

Specifications:

Excellent availability, Reduced customer inventories.
No minimum order, 1 piece stainless steel hollow bar order is accepted by Walmi Stainless Steel.
Improved cutting speeds and feed rates, better machine utilization and reduced fixed cost per produced stainless steel component.
Reduced tool wear, lower lubricant usage and machinery maintenance costs, better machine utilization through reduced stoppage time.
Less machine setting-up time and and machine cycle times, lower labor and overhead costs for each stainless component.
Faster machining, shorter production time due to excellent and consistent machining properties of stainless steel.
Easier handling due to lower weight per un-machined component of the hollow bar.
Very competitive from short to long series production of hollow bar compared to forging.
shorter production time for hollow bar compared to bore out solid stainless steel bar.
tangled chips can be avoided Due to limited internal machining
