Samuelson Sales supports industrial and refinery operations by sourcing stainless PVF through a broad network of OEMs and master suppliers. We are not tied to a single manufacturer or stocked product line, which allows us to support applications where service conditions, availability, lead times, and pricing drive decisions.
Our role is to help operations, maintenance, and project teams secure the right material for the service, whether the need is day-to-day MRO, outage work, or larger capital projects. Below is an overview of the types of stainless materials we regularly support for industrial and refinery environments.
Stainless Steel Pipe
We support sourcing of stainless pipe specified in applications where corrosion resistance, chemical compatibility, or service conditions make carbon steel unsuitable.
Welded Stainless Steel Pipe
- ASTM A312
- Grades 304/L and 316/L
- Sizes 1/4" thru 36"
- Schedules 10s, 20, 40s, 80s
Seamless Stainless Steel Pipe
- ASTM A312
- Grades 304/L and 316/L
- Sizes 1/4" thru 20"
- Schedules 10s, 40s, 80s, 160, XXH
- True Schedule 40 and True Schedule 80
Stainless Steel Flanges
We source stainless flanges applied in piping systems where bolted connections are required for equipment tie-ins, isolation, inspection, or maintenance access.
- ASTM A182
- Grades 304/L and 316/L
- Sizes 1/4" thru 24"
- Pressure ratings: 150#, 300#, 600#, and 1500#
- Weld Neck, Slip-On, Blind, Lap-Joint, Socket Weld, and Threaded
Stainless Steel Valves
We support sourcing of stainless valves for refinery and industrial services where corrosion resistance, chemical compatibility, pressure class, temperature, and emissions considerations drive selection.
- Stainless ball valves for isolation service
- Stainless gate and globe valves where flow characteristics or throttling requirements apply
- Stainless check valves where backflow prevention is required to protect equipment
- Pressure classes aligned to system design requirements
- End connections including flanged, buttweld, socket weld, and threaded
- Manual and actuated configurations based on control and access requirements
Valve sourcing is often coordinated with maintenance planning and outage schedules.
Buttweld Stainless Steel Fittings
We source buttweld fittings specified in piping systems where welded connections are required to manage pressure, temperature, and long-term integrity.
Welded & Seamless Buttweld Fittings
- ASTM A403 WPW, WPX, WPS
- Grades 304/L and 316/L
- Sizes 1/4" thru 24"
- Schedules 10s, 40s, 80s, 160
Configurations
- Long Radius 90, Short Radius 90, 45
- Tee and Reducing Tee
- Caps
- Concentric and Eccentric Reducers
- MSS Type A and Type C Stub Ends
Forged Stainless Steel Fittings
We support sourcing of forged stainless fittings for small-bore applications where pressure rating, connection type, and service conditions drive design requirements.
3000 lb Forged Stainless Steel Fittings
- ASTM A182
- Grades 304/L and 316/L
- Sizes 1/4" thru 4"
- Threaded and Socket Weld

150 lb Cast Stainless Steel Fittings
- Grades 304 and 316
- Sizes 1/4" thru 6"
- Threaded
Configurations
- 90, 45, Street 90
- Coupling, Half Coupling, Reducing Coupling
- Hex Bushing

- Union, Cross, Cap, Tee
Stainless Steel Branch Connections
We support sourcing of branch connections where branch take-offs from main headers are required, based on reinforcement, pressure, and layout considerations.
- ASTM A182
- Sizes 1/2" thru 2"
- Schedules 40s and 80s
- Pressure classes: 3000#, 6000#
- Buttweld, Socket Weld, and Threaded
