Dipti Metal Industries proudly stands as the largest global Hot Dip Galvanized (HDG) Threaded Pipe Fittings Manufacturer, supplier, stockist, dealer, distributor, and exporter from our base in Mumbai, India. We are recognized as a top worldwide leader for high-quality, corrosion-resistant threaded fittings. Our manufacturing capabilities, combined with our extensive global sourcing from trusted, certified partners, ensure that all products rigorously adhere to international standards, primarily ASME B16.11 and BS3799 for the fittings themselves, and specifically **ASTM A153** or **ISO 1461** for the hot-dip galvanization process. Our commitment ensures compatibility, safety, and superior performance across diverse industrial applications globally, particularly in environments prone to corrosion.
Hot Dip Galvanized Threaded Pipe Fittings are carbon steel fittings that undergo a process of immersion in a bath of molten zinc, creating a metallurgically bonded, highly durable zinc coating on their surface. This zinc layer acts as a sacrificial barrier, providing superior corrosion protection by corroding preferentially to the steel, thus extending the lifespan of the piping system. This makes HDG fittings an ideal choice for outdoor installations, marine applications, chemical processing plants, and any environment where moisture, salts, or other corrosive elements are present. Our comprehensive range of **HDG threaded fittings** includes **Elbows, Tees, Crosses, Couplings, Plugs, Caps, Bushings, Nipples, and Olets**. These are available in various nominal bore (NB) sizes (1/8″ NB – 4″ NB), pressure classes (2000lb – 9000lb), and thread types (NPT, BSPT, BSPP), specifically manufactured from carbon steel grades suitable for galvanizing. Our unwavering commitment to stringent quality control ensures that every HDG threaded fitting we supply meets precise dimensional, material, and galvanization specifications, providing robust and durable solutions for demanding industrial piping applications worldwide.

Hot Dip Galvanized (HDG) Threaded Pipe Fittings are carbon steel fittings that have been coated with a layer of zinc by immersing them in a bath of molten zinc. Their primary function is to provide superior corrosion resistance to the fittings, extending their lifespan and ensuring reliable performance in harsh, outdoor, or corrosive environments where bare carbon steel would quickly degrade. This zinc coating acts as a sacrificial layer, protecting the underlying steel.
The fittings themselves comply with dimensional and pressure standards like ASME B16.11 (Forged Fittings, Socket-Welding and Threaded) and BS3799 (Specification for Steel Pipe Fittings, Screwed and Socket-Welding). The hot-dip galvanization process and zinc coating quality are typically specified by standards such as ASTM A153 (Standard Specification for Zinc Coating (Hot-Dip) on Iron and Steel Hardware) or ISO 1461. These ensure both the fitting's mechanical properties and its corrosion protection meet stringent requirements.
Forged carbon steel fittings are typically used for hot-dip galvanization. Common material grades include ASTM A105 (for forged carbon steel fittings) and ASTM A350 LF2 (for low-temperature carbon steel forged fittings). These materials have compositions that are well-suited for the hot-dip galvanizing process, ensuring a strong metallurgical bond between the zinc coating and the steel substrate, resulting in excellent corrosion protection. Other materials are generally not hot-dip galvanized.
HDG threaded fittings are commonly used in applications requiring enhanced corrosion protection. This includes outdoor piping systems, marine environments, offshore platforms, agricultural irrigation, general plumbing in corrosive areas, water and wastewater treatment plants, power generation facilities (for cooling water lines), and any industrial setup exposed to moisture, chemicals, or atmospheric corrosion. They are preferred for their durability and extended service life.
