Malleable iron pipe fittings with the same diameter external thread, also known as external threaded straight connectors, are indispensable straight-through connectors in piping systems. They are primarily used for the precise connection of two internally threaded pipe fittings, valves, or equipment interfaces of the same diameter. Widely applicable to pipeline installation projects in various fields such as building water supply and drainage, HVAC, fire protection, and gas transmission, they combine practicality and durability.
The product is made of high-quality malleable cast iron (malleable iron) through precision casting and professional malleable annealing treatment. The material is tough and not easily broken, with excellent pressure resistance, capable of withstanding working temperatures from -20℃ to 300℃ and high-pressure media transportation. It is suitable for various common transportation media such as water, oil, air, and gas. The surface uses advanced hot-dip galvanizing technology to form a dense zinc-iron alloy layer, effectively resisting corrosion and rust, significantly extending service life, and suitable for various complex indoor and outdoor installation environments.
The threads are precisely and correctly machined, conforming to national standards, with clear and smooth textures. No complicated threading process is required during installation; the connection is convenient and tight, with excellent sealing performance, effectively eliminating the risk of leakage. With a full range of specifications and diameters from DN15 to DN100, it meets the needs of various engineering pipelines, offers excellent cost performance, and is delivered in a timely manner. It is the preferred accessory for pipeline connections in fields such as construction, chemical industry, and water conservancy, combining practicality and economy.
