Washer edge is beveled to prevent cutting of insulation material.


1, butt joint: the stress concentration is relatively small, carrying capacity is better.

2, Angle joint: bearing capacity is low, is generally not used alone, multi-purpose at the corner of the enclosed structure.

3, lap joint: stress distribution, low bearing capacity, simple preparation and equipment.


Cup head weld pins are specialized fasteners used in insulation applications. They are commonly used in the following applications:
HVAC insulation: Cup head weld pins are widely used in heating, ventilation, and air conditioning systems for securing insulation materials to metal ducts and pipes. They are used to fasten insulation boards, blankets, or wraps onto the surface, ensuring proper insulation and preventing heat transfer or condensation.

Refrigeration insulation: Cup head weld pins are also used in refrigeration systems, such as walk-in coolers or freezers, to attach insulation materials to refrigeration pipes, panels, or cabinets. Proper insulation is crucial in maintaining optimal temperature conditions and reducing energy consumption

Automotive insulation: Cup head weld pins find applications in automotive manufacturing, particularly in vehicles' exhaust systems. They secure insulation products like heat shields or exhaust pipe insulation wraps, enhancing thermal protection and reducing excessive heat transfer into the vehicle's interior or engine compartment.

With the cup-shaped head and steel construction, the cup head pins provide a secure and long-lasting hold, they are available in various lengths and gauges to suit all your industrial needs.
