Sunning Steel is a leading supplier of high quality stainless steel decorative pipes, offering a wide range of products for many decorative and structural applications.

Description: Polishing mirror welded pipe

Where to use welded stainless steel pipes
Welding stainless steel pipes is very popular. Compared to seamless products, they are cheaper and lighter in weight. Application of metal products:
Cold and hot water pipelines;
Assembly and installation of heating systems;
Used for the construction of supporting structures, frames, and floors.
In the above case, use circular cross-section pipes. Square products are popular in the manufacturing of industrial furniture, sports equipment, as well as the installation of railings, fences, canopies, parking booths, and street benches.
Stainless steel round pipes are the most suitable because compared to profiles, this type of profile has the best aerodynamic performance. The product is manufactured using welding method. Sunning Steel Limited provides stainless steel tube rollers such as ASTM (AISI), EN, JIS (SUS), GOST, etc. The product comes in dozens of sizes, different from steel brands, surfaces, cross-sections, wall thicknesses, and lengths.
Characteristics of welded pipes
Welding stainless steel pipes are metal products with the following characteristics:
They can withstand a pressure of 16 megapascals (160 atmospheres), which is 25% lower than the pressure that seamless pipelines can withstand.
They are produced using steel that is easy to weld. These brands of steel have different strengths and wear resistance.
Welding pipes are not easily bent, so fittings are used to connect them.
They have a relatively large diameter and lower wall thickness.


  1. High mechanical strength
    Pipes are resistant to various shock and deformation loads and wear, durable and practically do not lose their quality over time.
  2. Corrosion resistance
    Stainless steel pipes do not oxidize under the influence of moisture and aggressive environments. They are chemically inert and do not interact with liquids and gases.
  3. Resistance to changes in temperature and humidity
    Pipes are little susceptible to changes in linear dimensions when temperatures change and do not respond to changes in humidity and pressure, which allows them to be used in the most severe conditions.
  4. High ductility
    Stainless steel pipes are easy to process because they are ductile and not brittle, which allows them to be bent at the desired angles and given the desired shape.
  5. Aesthetic appearance
    Stainless steel looks great even without additional processing - painting or polishing.

Scope of application of welded pipes

Reliable and relatively lightweight welded stainless steel pipes are used for assembling heat exchangers and heaters, when laying utilities and pipelines in enterprises:

chemical and oil refining industries;

mechanical engineering and shipbuilding;

food sector.

Rectangular pipes can act as the basis of many metal structures. Rectangular rolled products are used to install fences and railings, load-bearing structures, furniture frames and vehicle elements. The advantages of such products are low weight and high strength. Manufactured from steel grades AISI 201, 304, 430.

Square pipes can withstand high loads, so they are installed as a reinforcing element in metal structures. Most often, square pipes are used when installing the frame of a structure or assembling a structure for a car body. Manufactured from steel grades AISI 430, 304.

Round pipes are the most common. They are widely used in pipelines for transporting liquids and gases under high pressure. The products are used in food, chemical, oil and other industries. We offer structural and special-purpose pipes. Manufactured from steel grades AISI 304, 316, 201.

Oval pipes have increased strength and a mirror surface compared to round products. Due to this, they are used as decorative elements in metal structures in furniture production and mechanical engineering. Manufactured from steel grades AISI 304, 316, 201.
