As a result, we deliver factory-direct pricing, consistent weld quality, and fast delivery. Similarly, this applies to all your boiler, furnace, and high-temperature lining projects.
In addition, we produce these weld stud anchors to comply with ISO 13918 for welded studs. Meanwhile, we use ASTM A108 cold drawn carbon steel as the base material. Therefore, they are ideal for anchoring refractory materials to boiler tubes and furnace shells.

- Finally, we provide Direct Factory Support. Tarco Industry provides technical guidance, samples, and custom production.
How to Install Boiler Tube Pin Refractory Anchors
- First, prepare the boiler tube surface. Clean the surface to ensure proper electrical contact for stud welding.
- Then, position the anchor. Place the pin perpendicular to the tube surface.
- Next, weld the pin. Use a drawn arc stud welder per ISO 13918 to weld the pin to the tube.
- After that, verify the weld. Check for full fusion and proper pin alignment.
- Finally, apply the refractory. Cast or gun the refractory material around the anchors.
Applications & Industries for Boiler Tube Pin Anchors
- For instance, in boiler tube walls, they anchor refractory material to protect tubes from high heat.
- Also, in industrial furnaces, they secure refractory linings on furnace shells and roofs.
- In addition, for power plants, they are used in boilers and high-temperature equipment.
- Furthermore, in petrochemical plants, they anchor refractory in reactors and heaters.
- Lastly, in cement kilns, they hold refractory bricks and castables in place.
