Stainless pipes & tubes are versatile material comprised of a steel alloy and a small percentage of chromium — the addition of chromium adds to the material’s corrosion resistance, a trait that earned stainless steel its name. Because stainless steel is also low-maintenance, oxidation resistant, and doesn’t affect other metals, it comes in contact with, it is frequently used in a large array of applications, especially in piping and tubing manufacturing.

Material stainless pipes & tubes grades
Stainless steel is one of the most popular and versatile materials. Stainless steel is an iron alloy that contains a minimum of 10.5% chromium. Alloying elements such as nickel, molybdenum, titanium, carbon, nitrogen, and copper can boost the strength, formability, and other properties of stainless steel. Different alloys offer different levels of corrosion resistance.

Stainless pipes & tubes Tolerance
In the production process, because the actual size is difficult to meet the nominal pipe size requirement, that is, it is often larger or smaller than the nominal size, so the standard stipulates that there is a difference between the actual size and the nominal size of the stainless steel pipe. A positive difference is called a positive deviation, and a negative difference is called a negative deviation.
Outside diameter (OD), wall thickness and length are three basic parameters in the process of manufacture and distribution for stainless steel tube & pipe, and these parameters have been standardized.
Outer diameter and wall thickness are particularly important, they are not only the basic support for meeting the design requirements of various types of applications such as strength, stiffness and fluid delivery, but also have a decisive influence on the subsequent processing, therefore, standards for stainless steel tube & pipe diameter and wall thickness of the manufacturing accuracy (tolerance) should been standardized.
What is Nominal Pipe Size and Actual Pipe Size
A. Nominal Pipe size: It is the nominal size specified in the standard such ASME B36.10m, ASME B36.19m, the ideal size that users and manufacturers hope to obtain, and the order size specified in the contract.
B. Actual Pipe size: It is the actual size obtained during the production process, which is often larger or smaller than the nominal size. This phenomenon of being larger or smaller than the nominal size is called deviation.
European Standard
European stainless steel tube & pipe standards specify 4 classes outer diameter and wall thickness in percentage or absolute value on the basis of nominal dimension.Generally, larger diameter or heavy wall thickness stainless steel pipe use percentage, small diameter or thin wall thickness stainless steel tube use absolute value.

Stainless Steel Density
Stainless steel density refers to substance mass per unit volume, it is one of typical property of stainless steel, commonly, density of stainless steel range from 7600 kg/m3 to 8000 kg/m3.
Stainless steel is a wide used material, containing at least 10.5% of Chromium, and other elements added to form stainless steel structure, these elements have Carbon, Silicon, Manganese, Phosphorus, Sulfur, Nickel, Molybdenum, Titanium and Copper, it is noted as high strength and excellent corrosion resistance.
Densities change depending on these alloy elements changing, different alloy content have different density value, even it is the same grade, it is difficult to calculate accurate density values, theoretic density value is given below for reference.
The following is the comparison of several commonly used stainless steel density, data may not be completely accurate, only for reference.
- Material 201, 202, 301, 302, 304, 304L, 305, 321
- Density 7.93 7.93 7.93 7.93 7.93 7.93 7.93 7.93
Seamless Tube Manufacturing Process
Seamless tubes are generally made in complex steps starting with the drilled hollows from billets, by cold drawing and cold rolling manufacturing process with cold drawing & cold rolling machines.
Stainless steel pipe polishing
Stainless steel pipe doesn’t look all shiny and new right off the welding line. In fact, it looks burnt and kind of charred. Polishing it will give it that mirror finish (or satin silver finish) that makes it such an attractive accessory. Stainless steel pipe polishing is an important process for manufactures and architectural applications. Polishing stainless steel pipes creates a uniform and consistent surface finish–vital for tank manufactures and OEMs supplying products to the chemical and pharmaceutical industries.
Beveling
Beveling Stainless Steel pipes contain one end angled, so that it mates with a complementary pipe end. Pipes can be beveled for certain applications in order to make welding of stainless steel pipes easier, which saves weld prep time and money compared to hand cutting.
Heat treating & Annealing
Stainless steel pipe annealing is an important production process and the heat treatment is mostly carried out under controlled conditions to avoid carburization, decarburization and scaling on the metal surface. Stainless steel pipe annealing is a solution treatment employed for recrystallizing the work-hardened austenitic stainless steels and drawing chromium carbides. In addition, stainless steel pipe annealing removes stresses occurred during sold-working, and homogenizes dendritic stainless steel welds.
UT testing
Ultrasonic Testing (UT) utilizes sound energy at high frequencies to provide examinations and measurements of the stainless steel product. This aids in flaw detection/evaluation, dimensional measurements, etc.
