Description
Schedule 40 304L Stainless Steel Welded Pipe - 20' Lengths
Schedule 40 304L Stainless Steel Welded Pipe provides a heavier-wall stainless piping option for welded industrial, mechanical, and process piping systems. Supplied in 20-foot lengths, this pipe is manufactured to ASTM A312 / ASME SA312 requirements and is designed for fabrication with compatible welded fittings and additional lengths of pipe.
Schedule 40 has a thicker wall than Schedule 10 stainless steel pipe, providing a more substantial pipe wall for applications where the selected system design requires Schedule 40 construction. This product is identified as Grade 304L stainless steel with welded pipe construction.

Schedule 40 Construction
Schedule 40 stainless steel pipe has a thicker wall than Schedule 10 pipe of the same nominal size. This results in greater pipe weight and a more substantial wall section.
Actual wall thickness varies by nominal pipe size. Verify the required diameter and Schedule 40 wall thickness before ordering, fabrication, or installation.
304L Stainless Steel
304L stainless steel is the low-carbon version of 304 stainless steel and is commonly used in welded piping and fabrication applications.
The material provides the corrosion resistance and fabrication characteristics associated with 304-series stainless steel while supporting compatible welded piping system construction.

Welded Pipe Construction
This product uses welded pipe construction. The pipe is formed and longitudinally welded during manufacturing, creating a weld seam as part of the finished pipe.
Field connections can be welded to compatible fittings and additional pipe lengths using an appropriate welding procedure for 304L stainless steel and the applicable piping system requirements.
Schedule 40 vs. Schedule 10
Schedule 40
- Thicker wall than Schedule 10
- Greater pipe weight per foot
- More substantial wall construction
- Used where Schedule 40 is specified by the system design
- This product configuration
Schedule 10
- Thinner wall construction
- Lower weight per foot
- Common where lighter-wall stainless pipe is suitable
- Different dimensional and mechanical characteristics
- Wall thickness varies by nominal pipe size
Advantages of Welded Connections
Permanent Piping Connection
- Creates a continuous welded assembly
- Suitable for compatible stainless steel weld fittings
- No threaded joint required
- Common in fabricated process piping
- Suitable for shop or field welding
System Fabrication
- Can be cut to required installation lengths
- Connects to additional welded pipe sections
- Supports fabricated piping layouts
- Compatible with appropriately specified weld fittings
- Useful in industrial and mechanical installations
Common Applications
