Product Description

Seamless Stainless Steel High Pressure Pipe: Engineered for Demanding Performance

This Seamless Stainless Steel High Pressure Pipe represents the pinnacle of durability and reliability for critical fluid transport systems. Manufactured as a seamless unit, it eliminates weld seams—the traditional weak points—delivering superior structural integrity and leak-proof performance under extreme conditions. Specifically designed to meet and exceed the rigorous demands of high-pressure applications, this pipe combines exceptional high tensile strength with the inherent corrosion resistance of stainless steel. It is the go-to solution for industries where safety, longevity, and unwavering performance are non-negotiable, particularly in challenging sectors like oil and gas. Available in custom lengths to minimize on-site welds and waste, it ensures a more efficient, cost-effective, and secure installation for your specific project footprint.

Product Characteristics & Advantages

•
Superior High Tensile Strength: The cold drawing or pilgering process used in manufacturing enhances the mechanical properties of the stainless steel, resulting in a pipe with exceptional high tensile strength. This enables it to withstand immense internal pressures, external loads, and mechanical stress without deformation or failure.
•
Seamless Construction: The absence of a longitudinal weld seam ensures a homogeneous structure with uniform strength and corrosion resistance throughout the pipe's circumference. This drastically reduces the risk of leakage and fatigue failure, especially in high-pressure, cyclic service common in oil and gas applications.
•
Exceptional Corrosion Resistance: Made from high-grade stainless steel, this pipe offers excellent resistance to a wide range of corrosive elements, including water, chemicals, and saline environments. This guarantees a long service life and reduces maintenance costs, even in harsh operating conditions.
•
Precision Manufacturing & Compliance: Our pipes are precision-engineered to adhere to stringent international standards, including ANSI B36.19, which specifies dimensions for stainless steel pipes. This ensures perfect compatibility with standard fittings, valves, and other system components.
•
Customization & Flexibility: We understand that projects vary. Therefore, we offer this Seamless Stainless Steel High Pressure Pipe in custom lengths. This tailored service helps reduce installation time, lower joint-related costs, and minimize material waste, providing a more economical and streamlined project flow.

Technology & Manufacturing Process

The production of this high-performance pipe begins with a solid, cylindrical billet of stainless steel. It is heated and pierced to form a hollow shell. Through a series of high-tech processes like hot extrusion, pilgering, or cold drawing, the shell is elongated and sized to achieve the precise diameter, wall thickness, and dimensional tolerance. The seamless pipe is then solution annealed to relieve stresses and restore optimal corrosion resistance, followed by pickling and passivation to remove scale and form a protective chromium oxide layer on the surface. Advanced non-destructive testing (NDT) methods, including hydrostatic testing, ultrasonic testing, or eddy current testing, are rigorously applied to ensure every inch of the pipe is free from defects and meets the highest quality standards.

Primary Applications

The core application of this Seamless Stainless Steel High Pressure Pipe is in the oil and gas industry, where it is used in:

•
Downhole tubing and casing
•
Process and instrumentation lines
•
Hydraulic lines
•
Heat exchanger tubes

•
Power generation (including nuclear)
•
Shipbuilding and offshore platforms
•
High-pressure fluid and gas transmission systems

Service & FAQ

We provide comprehensive technical support and customer service. Our team can assist with material selection, specification review, and logistics planning.

•
Q: What are the benefits of seamless pipe over welded pipe for high-pressure use?

A: Seamless pipes have no weld seam, making them stronger, more reliable, and less prone to leakage under high pressure and corrosive conditions.
•
Q: Can you supply pipes according to other international standards?

A: Yes. We can manufacture pipes conforming to DIN, JIS, EN, and other major standards upon request.
•
Q: What is the typical lead time for custom length orders?

A: Lead time varies based on specification and quantity. Please inquire for a specific project schedule.
