A Forged Pipe Plug is a solid, high-strength component used to seal the end of a piping connection, effectively stopping the flow within a pressure system. These plugs are part of the ASME B16.11 forged fittings range and are typically installed at unused outlets, branch connections, or during pressure testing operations. Depending on the configuration, they can be supplied with either Threaded (NPT/BSP) or Socket Weld ends.
Forged plugs are produced from forged bar stock or billets, offering superior strength, leak-proof performance, and high pressure resistance. They are commonly used in oil & gas pipelines, petrochemical plants, power stations, marine applications, and other industrial sectors where mechanical reliability is non-negotiable. Different styles like Hex Head, Square Head, Round Head, and Countersunk (Flush) Plugs provide flexibility for specific access and sealing requirements.
Quality is at the core of our forged fittings manufacturing process. Each Forged Pipe Plug is produced in accordance with international specifications such as ASME B16.11, BS 3799, MSS-SP-79, and MSS-SP-83. We ensure full traceability and compliance with material and dimensional standards, which is crucial for performance under high-pressure and high-temperature environments.
Our manufacturing facilities are ISO 9001:2015 certified, and we provide comprehensive Mill Test Certificates (MTC) as per EN 10204 3.1/3.2, along with third-party inspection reports if required. We also comply with PED 2014/68/EU, NACE MR0175, and IBR standards for applicable materials and service environments. Every plug is tested for pressure integrity, dimensional accuracy, and surface finishing, ensuring leak-tight sealing even in the most critical operations.
To ensure safe handling and transportation, Nutech Overseas follows industry-best packaging practices for all Forged Pipe Plugs. Each plug is cleaned, capped, and protected with rust-preventive coatings before being packed. We use fumigated wooden boxes, corrugated cartons, or bubble-wrapped bundles—depending on the order volume and customer preferences.
Proper labeling includes material grade, size, pressure class, heat number, and purchase order details to maintain full traceability. For overseas clients, we offer export-worthy seaworthy packaging compliant with international logistics standards. Whether shipping by air, sea, or land, we ensure timely and secure delivery to destinations across the USA, Europe, Middle East, and Asia through trusted freight partners.
We manufacture and supply a comprehensive range of Forged Pipe Plugs to meet diverse industry requirements and pressure classes. The main types include:
- Square Head Plug:
Commonly used in pipelines requiring frequent maintenance; allows easy removal using standard tools.
- Hex Head Plug:
Offers a flush surface with a hexagonal head for wrench-tightening in high-pressure systems.
- Round Head Plug:
Ideal for applications where aesthetic appearance and minimal projection are important.
- Countersunk Plug (Flush Plug):
Designed to sit flush with the pipe surface, reducing obstruction and allowing internal cleaning.
- Socket Weld Plug:
Welded into place for permanent sealing in high-pressure and high-temperature piping systems.
- Threaded Plug (NPT/BSP):
Screwed into threaded openings to provide a strong and leak-proof seal in temporary or low-pressure applications.
We proudly serves a global clientele by exporting ASME B16.11 Forged Pipe Plugs to over 45 countries. Our high-performance Threaded, Socket Weld, and Flush Type Plugs are trusted by engineers and procurement teams across key industrial hubs.

Absolutely. Forged Pipe Plugs can be custom-engineered to perform reliably in some of the harshest industrial conditions—including offshore drilling platforms, cryogenic systems, and high-temperature refinery operations.
In these environments, material selection is crucial. We offer plugs forged from a wide array of premium materials like Stainless Steel 316/L for corrosion resistance, Alloy Steel F22 for high-temperature tolerance, and Duplex/Super Duplex (F51, F55) for enhanced strength and seawater durability. For cryogenic services, Carbon Steel A350 LF2 CL.1 is often used due to its low-temperature impact toughness.
Moreover, we ensure compatibility with ASME B16.11, MSS-SP-79, and BS 3799 standards and provide threads like NPT and BSP, as well as pressure ratings from 3000# to 9000#, tailored for high-demand applications.
When choosing a forged pipe plug for high-pressure systems, consider:
- Pressure Class: Choose from 3000#, 6000#, or 9000# based on system pressure.
- Connection Type:
- Threaded Plugs (NPT/BSP) – Easy to install.
- Socket Weld Plugs – Stronger, leak-proof joints.
- Material Compatibility:
- Carbon Steel A105 – For general use.
- Stainless Steel 304/316 – For corrosion resistance.
- Alloy Steel F11/F22 or Duplex F51/F55 – For extreme conditions.
- Plug Type Selection:
- Square Head, Hex Head, Round Head, Bull Plug, or Countersunk (Flush) Plug.
