Welker Solid Probe

Solid Probe

One-piece stainless steel probe construction for rugged sampling and injection service.

The Welker Solid Probe is a rugged one-piece 316/316L stainless steel pipeline probe designed for sampling and injection applications in natural gas, oil, and petrochemical service. Machined from a single solid bar, the Solid Probe eliminates welds that can become vulnerable to corrosive attack, helping improve strength, durability, and long-term reliability. Built for demanding process conditions, the Solid Probe provides a robust sample or injection point for operators who need a corrosion-resistant alternative to welded probe designs.
