Malleable iron pipe fittings, also known as straight couplings or pipe clamps, are indispensable straight connectors in piping systems. They are specifically designed for the secure connection of two pipes of the same specification and are widely used in various pipeline projects in construction, industry, and municipal engineering. The products are precision cast from high-quality malleable cast iron (malleable iron) and annealed at high temperatures, possessing both high strength and toughness with excellent machinability. They are not easily broken or deformed during installation, exhibiting outstanding durability.
The surface uses an advanced hot-dip galvanizing process to form a dense zinc-iron alloy layer, effectively resisting erosion in humid and corrosive environments, significantly extending service life and adapting to various complex working conditions. The precision-machined internal threads ensure a tight fit; when used with PTFE tape for sealing, it effectively eliminates the risk of leakage. Installation is convenient and efficient; basic installation can be completed after manual tightening, reducing construction costs.
A complete range of specifications is available, covering the entire series from DN15 to DN100, corresponding to various common sizes from 4 points to 4 inches, precisely adapting to different pipe diameter requirements. Sufficient stock is available for on-demand supply. The product conforms to national industry standards, has undergone rigorous quality testing, and boasts a pressure resistance of up to 2.5MPa. It is suitable for temperatures ranging from -20℃ to 300℃ and can be used in various pipeline systems, including water supply, fire protection, gas, and compressed air.
With outstanding cost-effectiveness and stable quality, it is the preferred choice for safe and reliable pipeline connections, whether for new construction projects or the repair and replacement of old pipelines, ensuring smooth and stable pipeline systems throughout the entire process.
