High-Quality Stainless Steel Pipe & Tube for Industrial Use
Welded and seamless stainless steel pipes in 304, 316L, and other grades for construction, fluid transport, and structural applications.
What Are Stainless Steel Pipes & Tubes?
Stainless steel pipes and tubes are long, hollow sections used for fluid transport, structural support, or decorative use. They are valued for their corrosion resistance, durability, and clean finish.
The key difference:
Pipes are generally used for transporting fluids or gases (focus on pressure & internal diameter)
Tubes are often structural or decorative (focus on outer dimensions & finish)
Available in round, square, and rectangular shapes and used in construction, chemical plants, marine structures, furniture, and mechanical systems.

Performance Characteristics and Applications of Stainless Steel Pipes
I. Performance Characteristics
Corrosion Resistance
The surface of stainless steel pipes forms a dense passivation film, effectively resisting corrosion from the atmosphere, water, and chemical media, maintaining stable appearance and performance over a long period. Its resistance to acid, alkali, and salt corrosion makes it particularly suitable for harsh environments such as chemical and petroleum industries.
High Temperature Resistance
It is not easily deformed, discolored, or oxidized in high-temperature environments and can withstand extreme temperature conditions (e.g., -270℃ to 400℃), making it suitable for high-temperature equipment such as boilers and heat exchangers.
Mechanical Properties
High tensile strength (>530N/mm), combined with toughness and ductility, enabling it to withstand high pressure and heavy loads, avoiding the risk of bursting or leakage.
Hygiene and Environmental Protection
The material is non-toxic and harmless, with a smooth inner wall that does not accumulate scale, eliminating secondary pollution and meeting drinking water standards; it is also 100% recyclable, reducing the environmental burden.
Aesthetics and Processability
The surface can be polished, brushed, or matte, offering a strong metallic texture and diverse shapes; excellent cold working and welding performance, facilitating stamping, bending, and other forming processes.
II. Main Applications
Architecture and Decoration
Civil Applications: Used in decorative projects such as stair railings, doors and windows, guardrails, and ceilings, enhancing the modern feel and structural strength of buildings.
Public Spaces: Widely used in interior and exterior decoration of shopping malls, hotels, and offices, such as furniture frames and artwork production.
Industrial Applications
Fluid Transportation: Used in the petrochemical and food industries to transport corrosive media, ensuring safe operation under high temperature and high pressure conditions.
Mechanical Construction: As a core component of boilers, heat exchangers, and piping systems, extending equipment lifespan.
Public Welfare Applications
Drinking Water Systems: Used as domestic water supply pipes, resistant to freezing and cracking, preventing bursts and ensuring water safety; service life can reach 100 years.
Bathroom Fixtures & Furniture: Used to manufacture bed frames, chairs, and bathroom fixtures, combining durability and a high-end feel.
Special Applications
Marine Engineering & Pharmaceuticals: Providing stable and reliable pipeline solutions in highly corrosive environments, such as offshore platforms and chemical plants.

Frequently Asked Questions
Q1: What’s the difference between seamless and welded pipes?
A:
Seamless pipes have no weld seam and are used for high-pressure and critical applications. Welded pipes are more economical and suitable for general use.
Q2: Do you offer decorative pipes with mirror finish?
A:
Yes. We supply tubes with mirror (8K), brushed (No.4), and hairline finishes for decorative applications.
Q3: Can stainless pipe be used outdoors?
A:
Yes. Grades like 304 and 316 are suitable for outdoor use, especially 316 for marine or coastal environments.
Q4: What is the tolerance for OD and wall thickness?
A:
Standard tolerance applies per ASTM A554 / A312, and tighter tolerances available upon request.
Q5: Can you do custom lengths or perforated tubes?
A:
Absolutely. We support CNC cutting, perforation, and slotting per customer drawings.
