Piyush - Model 304H -Stainless Steel Pipes

About 304H pipes-

Stainless Steel S30409 Seamless Pipe are basically austenitic stainless steel that is well tested and is securely verified by the quality controller so as to make sure a high performance, best strength, and categorical quality product. The pipes can be easily grouped in appropriate thickness, surface finish, length, and width. The alloy pipes can also be served in cut-to-length size and it can be machined as well as fabricated so that it correctly meets the requirement of the client. It is basically a modified version of 304 with more controlled carbon content in the range of approx. 0.04-0.10 for desired strength at a particular temperature such as 800 deg F.

Stainless steel pipe properties-

The stainless steel 304H pipe possesses high corrosion resistance and it contains an appropriate amount of chromium. The chromium is responsible for forming a self-healing layer of oxide that gives stainless steel pipe their corrosion resistance properties. It also offers resistance at cryogenic temperatures. Cryogenic resistance can be easily measured by toughness or ductility at zero temperature. It has a high tensile strength at ambient temperature. It has maintained excellent toughness. The strength of the pipe is achieved through cold working and thus fabrication component receives appropriate strength. It can recollect the strength at some eminent temperature. The high chromium content helps to resist scaling at peak temperatures. The pipe offers great ductility and work hardening allow the formation of stainless steel using severe processes like deep drawing. In comparison to mild steel, it has strength double. Other known properties of SS 1.4948 Welded Pipe are heat resistant qualities, great creep strength, and high tensile yielding strength. In contrast, it offers high weldability, corrosion as well as oxidation resistance so that it performs well. It has a typical application such as commercial and home application including container and tank for a variety of solid and liquid.

Testing-

Various test got performed on stainless steel pipes after its manufacturing and are follows-

• Mechanical testing
• Chemical analysis
• Flattening test
• Pitting resistance test
• Macro and micro test
• Positive material identification test
• Flaring test
• Intergranular corrosion test or IGC test

The product is certified too, raw material certificate, EN 10204/3.1B, and third-party inspection report are some of them.

Documentation-

After testing comes to the documentation. Documentation plays an essential part because it is proof that the product is well tested and the quality is maintained. It also tells about the product credibility and ease of work. They are as follows-

• Certificate of origin
• Packing list
• Commercial invoice
• Quality assurance plan
• Heat treatment charts
• Material traceability records
• Fumigation certificates
• Material test certificate
• Guarantee letter
• NABL approved test reports
• Form A of Generalized system of preferences
• Welding procedure specification

SS 304H Pipe Packaging-

The stainless steel 304H pipes can be packed using polypropylene sheets, flat steel bands, wooden cases, wooden pallets, and wooden boxes. It can be shipped in bundles so as to prevent it from rusting and damages. The product can be marked or labeled so that it doesn’t get lost. With capped end pipe of around 3,” OD is supplied in bundles.
