Engineered for secure, high-strength insulation fastening. Our cup head weld pins feature a cupped head and precision-welded construction, designed to anchor insulation within removable blankets and secure it to HVAC sheet metal, ensuring long-term thermal and acoustic performance.

Key Features:

Cupped head insulation pins, also known as Insulation quilting pins, are critical components in both permanent and reusable insulation systems. They are primarily used to provide support and prevent insulation materials from settling or sliding within fabricated blankets and covers. Additionally, they can be applied with a capacitor discharge stud welder to permanently secure insulation to ductwork and other HVAC sheet metal configurations.

• Reliable Insulation Support: Designed to anchor insulation within removable blankets, ensuring uniformity and preventing the insulation from sagging or shifting over time.

• Dual Functionality: While commonly used as a hookless lacing anchor for fabricating blankets, these pins also serve as a weld pin for permanent attachment to metal surfaces.

• Corrosion-Resistant Materials: Manufactured from high-grade 304/316 stainless steel or galvanized steel, providing superior resistance to oxidation, rust, and chemical corrosion in harsh environments.

• Precision Engineering: Available in standard 12 Gauge (2.7mm) and 14 Gauge (2.0mm) pin diameters with sharp tips for easy penetration through insulation without excessive damage.

• Versatile Length Options: Standard lengths of 1″, 1-1/2″, 2-1/2″, and 4-1/2″ accommodate various insulation thicknesses, with custom lengths available upon request.

Application

Our Cup Head Weld Pins are widely used in commercial and industrial insulation fixing:

• HVAC ductwork – internal and external thermal/acoustic lining

• Industrial piping and vessel insulation

• Power generation and boiler cladding

• Commercial building mechanical rooms

• Removable insulation jackets and blankets (when used with self-locking washers)

Compatible insulation materials:
Mineral wool, fiberglass wool, rockwool, ceramic fiber blankets, and composite insulation boards.

Compatible substrates:
Carbon steel, galvanized steel, and stainless steel (must be conductive for stud welding).

FAQ

• What is the difference between cup head weld pins and lacing anchors?
  Cup head weld pins are typically used as hookless fasteners to secure insulation inside blankets, while lacing anchors feature a hook for lacing wires. However, cup head weld pins can also serve as weld pins for permanent attachment.

• What pin length should I choose for my project?
  The pin length should be slightly longer than the insulation thickness to allow for the self-locking washer to be placed and secured. Standard lengths range from 1″ to 4-1/2″.

• Are these pins suitable for high-temperature applications?
  Yes, our stainless steel cup head weld pins are designed to withstand elevated temperatures and provide durable, long-term fixings in demanding industrial environments.

• Can I place a custom order?
   Yes. Please contact our sales team with your specific requirements, and we will do our best to accommodate them.

• Do you provide samples? How can I get one?
