Product Description

Product Description

 

Stainless steel welded pipe is a crucial component in various industries, known for its durability, corrosion resistance, and versatility. This type of pipe is manufactured by welding together two or more pieces of stainless steel, creating a strong and seamless connection. Unlike its counterpart, the seamless pipe, welded pipe offers unique advantages in terms of cost-effectiveness and dimensional consistency.

Grades and Specifications

Stainless steel welded pipes are available in various grades and specifications to meet different industry requirements:
 
A. Common grades: The most frequently used grades include 304, 304L, 316, and 316L. Each grade offers specific properties suitable for different applications.
 
B. ASTM A312 specification: This is a standard specification for seamless, welded, and heavily cold worked austenitic stainless steel pipes.
 
C. Size ranges and schedules: Stainless steel welded pipes are available in a wide range of sizes, typically from 1/4" to 36" NPS (Nominal Pipe Size). Common schedules include 10, 10s, 40, 40s, 80, and 80s.
 
D. Wall thickness: The wall thickness of welded pipes is generally more consistent than that of seamless pipes, which can be an advantage in certain applications.


 

Benefits of Stainless Steel Welded Pipe

The advantages of using stainless steel welded pipes include:
 
A. Excellent corrosion resistance: This property ensures the longevity and integrity of piping systems in various environments.
 
B. High strength-to-weight ratio: Stainless steel welded pipes offer robust performance without excessive weight.
 
C. Resistance to high temperatures and pressures: This makes them suitable for demanding industrial applications.
 
D. Aesthetic appeal: Their polished appearance makes them attractive for visible installations.
 
E. Cost-effectiveness: Compared to seamless pipes, welded pipes are generally more affordable, offering a balance between performance and cost.

5. Can we visit your factory?
-- Warmly welcome. Once we have your schedule, we will arrange the professional sales team to follow up your case.

6.What is our need pay attentation to Seamless Steel Pipe for Fluid Transportation?
--The steel used in seamless pipes is selected for its compatibility with the fluid being transported. This is particularly important for aggressive fluids that could cause corrosion.To ensure the integrity of the stainless steel seamless pipes, seamless steel pipes often undergo non-destructive testing, such as ultrasonic testing, to detect any internal or external defects that could affect fluid transportation.Depending on the application, seamless steel pipes may be coated or lined to provide additional protection against corrosion or to accommodate specific fluid types, such as chemicals or drinking water.
