Product Description

Types of Stainless Steel Pipe

First, let's dive into the many different types of stainless steel pipe so that we can judge which types to use for each different scenario.

Seamless Pipe

A seamless pipe is a pipe that does not contain any seams or weld joints. It's capable of standing up to intense levels of pressure and also temperatures thanks to the metal itself. It's used in a wide variety of different oil and gas applications, but they are also used in mechanical and engineering industries too. This makes seamless pipes rather versatile and they are always inspected with high levels of precision to ensure the quality of the material.

Welded Pipe

Welded pipes can be used in virtually every industry thanks to its flexibility. However, they fare better in corrosion resistance as opposed to withstanding pressure. Because of the materials used and the lightweight nature of welded pipes, they're far more cost-effective than most other piping methods and offer the best value for your money.

• ASTM (USA):

• A312: Seamless and welded austenitic stainless steel pipes (covers 304, 316, 310S).

• A790: Duplex and super duplex stainless steel pipes (2205, 2507).

• EN (Europe):

• EN 10216-5: Stainless steel pipes for pressure purposes at high temperatures.

• EN 10312: Stainless steel pipes for fluid transport (including hygienic standards).

• JIS (Japan):

• G3463: Stainless steel pipes for heat-exchangers (SUS304, SUS316).
• • Chemical Analysis: Optical emission spectroscopy to verify Cr, Ni, Mo content (tolerance ±0.5% for major elements).
  • Mechanical Testing:
  • Tensile test (ISO 6892-1): Ensures strength and ductility meet grade requirements.
  • Flattening/Flaring Test: For welded pipes, to check seam integrity under deformation (ASTM A999).
  • Corrosion Testing:
  • Salt Spray (ASTM B117): 1,000-hour test for marine-grade pipes (316/2205).
  • Intergranular Corrosion (ASTM A262 E-test): Critical for welded joints to avoid sensitization.

• Corrosion Resistance: Eliminates need for frequent coatings/maintenance in harsh environments, reducing lifecycle costs.

• Design Flexibility: Wide range of grades/sizes for pressure ratings (10 bar to 1,000 bar) and temperature extremes (-200°C to 1,200°C).

• Hygienic Properties: Smooth surfaces meet strict food/medical safety standards (no pores for bacterial growth).

• Recyclability: 100% recyclable, with 85% of stainless steel pipes sourced from recycled materials.

 

Stainless steel pipes are indispensable in modern industry, combining corrosion resistance, mechanical robustness, and design versatility to meet the most demanding environmental and operational challenges. From transporting critical fluids in oil rigs to ensuring hygiene in pharmaceutical plants, their reliability and adaptability make them a preferred choice across sectors. As global focus shifts to sustainability and high-performance engineering, ongoing innovations in alloy technology and manufacturing will further expand their applications, solidifying their role as a backbone material for industrial progress.

Stainless steel pipes are widely used due to their durability, corrosion resistance, and ability to withstand high pressure and high temperature. They are mainly used in industrial pipelines such as petroleum, chemical, medical, food, light industry, mechanical instruments, and mechanical structural components. In addition, when the bending and torsional strengths are the same, the weight is lighter, so they are also widely used in the manufacture of mechanical parts and engineering structures. They are also often used in furniture and kitchenware.
 

Specific Applications:

• Food and Beverage:

  Stainless steel pipes are essential for transporting fluids in food processing and beverage industries due to their hygienic properties and resistance to corrosion from acidic substances. 

   
• Oil and Gas:

  Their corrosion resistance and strength make them ideal for transporting crude oil, natural gas, and refined products, both onshore and offshore. 

   
• Chemical Processing:

  Stainless steel pipes are used in chemical and petrochemical plants for conveying various chemicals, acids, and gases, including those at high temperatures and pressures. 

   
• Construction:

  They are used for structural support and design elements in buildings and infrastructure, as well as in plumbing systems. 

   
• Water and Wastewater Treatment:

  Their resistance to chemicals and high pressures makes them suitable for transporting water, sewage, and treated effluent in water treatment plants. 

   
• Pharmaceutical Industry:

  Like food processing, stainless steel pipes are used to ensure high levels of cleanliness and prevent corrosion in pharmaceutical applications.
