Stainless Steel Pipes and Stainless Steel Tubes from us are of the highest quality, and they will be resistant to corrosion for years to come, as well as being strong, durable, and easy to machine. In addition to the standard size of these SS Pipes and SS Tubes, we are also specialized in providing our customers with custom-sized pipe and tube requirements.
It is possible to purchase stainless steel seamless pipes in compliance with ASTM A213 and ASTM A269 as well as in standard tube sizes and wall thicknesses in the common grades of stainless steel, such as stainless steel 304 and stainless steel 304L.
These instrumentation tubes are used primarily in petrochemical plants, oil and gas equipment, heat exchangers, sea water applications, pharmaceutical industry, general fabrication, chemical processing equipment, food and beverage industry, and water treatment plants, and are primarily used in these areas. Water, oil, and gas can all be transported with stainless steel pipes and tubes that will withstand harsh climatic conditions and high internal and external pressures.
In this particular alloy, titanium is widely used as a means of preventing intergranular corrosion and is widely used in damaging temperatures. This alloy is a popular form of stainless steel widely used in damaging temperatures. As the titanium reacts with the carbon during the manufacturing process, it produces a coating of titanium carbide that is rust-resistant. Chromium is not retained in the alloy in order to provide a high tensile strength, as well as to fight the corrosion. Titanium, on the other hand, prevents the formation of chromium carbide in the material.
Owing to these properties, we have used this alloy to manufacture the excellent range of 321 321H Stainless Steel Pipe. These are developed in accordance to the ASTM standards. Our complete inventory consists of seamless pipe and weld pipe. These pipes are highly immune to inter granular corrosion and carbide precipitation. Moreover, these exhibit excellent weldability.

Features of SS 321 / 321H Pipes
- Corrosion resistance between the grains of the material
- They provide resistance to corrosion
- Helps to Prevent the formation of carbide
- Can easily withstand very high temperature
- They manifest high tensile strength
- Show high resistance to stress cracking
Advantages of SS 321 / 321H Pipes
Weldability, formability, and fabricability are some of the advantages of this product. The inner surface of the pipe is smooth from the inside of the pipe, which reduces pressure and turbulence. The product has good strength compared to other products. With its welded system, it provides more space for workers to work.
Why is material testing so important?
The purpose of material testing is to ensure that the product is in good condition and of high quality by testing it by a professional. There are a number of strict tests that the product has to go through, such as flattening, flaring, intergranular corrosion, micro and macro tests, hardness tests, chemical analysis, and spectrometry. A variety of other tests are also carried out, such as mechanical testing, positive material identification, or PMI testing, pitting resistance tests, etc.
How a product’s documentation is done?
It is the responsibility of the company to provide the product with the necessary documentation by issuing it with certificates and reports so that it can be clarified properly. As an example, we can use quality assurance plans, guarantee letters, heat treatment charts, traceability records, welding procedure specifications, commercial invoices, certificates of origin attested by the embassy, fumigation certificates, raw material test reports, etc.
