ASME B16.11 Square Head Plug

ASME B16.11 Square Head Plug Supplier | Precision Engineered for High-Pressure Sealing

At Xi’an QinSteel Trading Co., Ltd, we specialize in manufacturing ASME B16.11 Square Head Plugs that meet stringent global standards. With over a decade of expertise in pipe fittings, we deliver robust solutions for oil & gas, chemical processing, and industrial systems. Our plugs combine precision engineering with rapid order fulfillment, ensuring leak-proof performance even in extreme conditions.

Product Overview

The product is designed for secure, high-pressure sealing in piping systems. Available in Socket Weld or Threaded connections, these plugs comply with ASME B16.11 and BS 3799 standards, offering unmatched durability in sizes from 1/8" to 4". Ideal for permanent or removable installations, they withstand pressures up to 9000LB, making them a trusted choice for critical applications.

Key Specifications

Why Our ASME B16.11 Square Head Plug Stands Out？

① Square Head Design for Secure Installation

The square head ASME B16.11 Square Head Plug allows easy torque application with standard wrenches, minimizing slippage during installation. This design ensures proper sealing force in tight spaces, outperforming hex-head alternatives.

② Dual Connection Versatility

Choose between Socket Weld for permanent, vibration-resistant joints or Threaded connections for easy maintenance. Both options meet ASME B16.11 tolerances for precise fitment.

③ Extreme Pressure & Temperature Resistance

Engineered for 3000LB–9000LB systems, our plugs maintain integrity in temperatures from -50°F to 1200°F. Materials like A350 LF2 (low-temp) and SS316 (corrosion-resistant) cater to harsh environments.

④ Global Compliance & Traceability

Every plug includes mill test reports (MTRs) and complies with ISO 9001, API 6A, and PED certifications. Regional-specific variants (CE, GOST, CCS) simplify global procurement.

⑤ Rapid Customization & Sampling

Need non-standard sizes or coatings? Our R&D team delivers OEM/ODM solutions within 3 weeks, with samples available for quality verification.

Applications

• Oil & Gas: Seal wellhead equipment, pipelines, and valves (API 6A compliant).
• Chemical Processing: Corrosion-resistant SS316 plugs for acidic environments.
• Water Treatment: Durable A105 carbon steel plugs for high-pressure filtration systems.
• Power Generation: High-temperature alloys for steam lines.

Quality Assurance

• 100% pressure testing per ASME B16.11 protocols.
• Dimensional checks with coordinate-measuring machines (CMM).
• Surface finish inspection to prevent galling.

Packaging & Logistics

• Export-grade wooden crates with anti-corrosion VCI packaging.
• Global shipping via DHL, FedEx, or sea freight.
• 98% on-time delivery rate for bulk orders.
