Walmi manufacture seamless stainless steel tubing as per ASTM A269/ASME SA269, A213, A270, including an extensive material of austenitic stainless steel 304/304L,316/316L, 310S,317L,321 etc, duplex stainless steel S31803/S32205, super duplex stainless steel S32750 and High-alloy austenitic stainless steel 904L(N08904).
Sizes range from 12mm to 323.9 mm ( NPS 1/4”-DN8 to NPS 12”-DN300) outside diameter with a full tubes schedules ranging from sch5 through double extra heavy.
The seamless stainless steel tubings are usually delivered in 5.0m-8.0m random lengths or cut to fixed lengths. But Walmi can supply seamless stainless steel tubing in most grades exceeding 15m long. All tubes can be cut to customer’s exact requirements.
Walmi Stainless Steel Seamless tube are austenitic stainless nominal wall thickness tubing for general corrosion-resisting service and low- or high-temperature service. The stainless tubes are used extensively in the following industries:
♦ Gas sensors
♦ Gasoline direct injection system
One-stop service for industrial stainless steel tubular products, including Pipes, Tubes, Butt-Welding Fittings, Forged Piping Flanges and Valves.
Value-added service are available in the following:
♦ Color Coding
♦ Welded with Flanges & Fittings
♦ Stocking for fast delivery
♦ Customized production for hard-to-source grades and sizes.
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.
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
