China SMLS Pipe Manufacturer  offers ASME 36.19 ASTM A312 TP904L SMLS Pipe, 1/2 Inch, SCH10S.

ALLOY 904L is a multipurpose highly corrosion resistant stainless steel. The chromium, nickel, molybdenum and copper content of the alloy renders it suitable for many applications dealing with medium to corrosive environments. It is particularly useful in sulphuric acid applications where the range of concentrations and temperatures in which it can be used, is wider than that for grades such as 317L and duplex grade ALLOY 2205. This is in part due to the copper content of the alloy. In industrial grade phosphoric acid environments, the performance of ALLOY 904L / 1.4539 is again superior to that of 317L stainless steel and, at higher temperatures, duplex grade ALLOY 2205 as well. Performance in phosphoric acid is strongly influenced by the level of impurities present. The Alloy also has useful resistance to organic acids such as formic and oxalic acids. With respect to localised corrosion, the high nickel content of ALLOY 904L / 1.4539 makes it more resistant to stress corrosion cracking than other common austenitic stainless steels whilst the levels of chromium, molybdenum and nitrogen impart excellent resistance to pitting and crevice corrosion.

Typical physical properties of grade 904L stainless steels

Application of ASME 36.19 ASTM A312 TP904L SMLS Pipe 1/2 Inch SCH10S:

• • Food processing equipment, particularly in beer brewing, milk processing & wine making.
  • Kitchen benches, sinks, troughs, equipment and appliances
  • Architectural panelling, railings & trim
  • Chemical containers, including for transport
  • Heat Exchangers
  • Woven or welded screens for mining, quarrying & water filtration
  • Threaded fasteners
  • Springs
  • Others

Other Features:

1) Chemical and Physical characteristic: durable, corrosion resistant and high-temperature resistant

2) We also produce pipes with special specifications according to customers’ requirements;

TP904L SMLS pipe is a tubular section or hollow cylinder, usually but not necessarily of circular cross-section, used mainly to convey substances which can flow — liquids and gases (fluids), slurries, powders and masses of small solids. It can also be used for structural applications; hollow pipe is far stiffer per unit weight than solid members.

TP904L SMLS pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable. Historically seamless pipe was regarded as withstanding pressure better than other types, and was often more easily available than welded pipe.

• • TP904L SMLS pipe‘s Marking & Packaging

While marking we choose a specific item number as well different color shade to differentiate steel grades. We mark TP904L SMLS pipe as needed with the most suitable & visible marking technique.

Packaging is an integral part of the product. It guarantees that the TP904L SMLS pipe is delivered to the customer in the required quality. For smaller orders the size of the TP904L SMLS pipe bundle depends on the no. of Tubes ordered, for larger orders the tubes are packed into individual bundles and in such a way that the maximum weight of 4000kg per bundle is not excedded. Bundle tied down with steel tape. Bundle tied down by steel strap underlaid by tapaten.

We can also provide TP904L SMLS pipe wooden box packing, cardboard boxes, plastic wrapping, using hardened paper with PE meshing (used as protection against mechanical damages of tubes), into tapaten and polyethylene sheet etc.
