PRODUCTS DETAILS
Malleable Iron LCC Long Compression Coupling. LCC is a kind of connection pipe fittings commonly used in plumbing installation,Fire Protection,Waterworks,HVAC,Plumbing,GAS,Irrigation,or other piping systems. It is used for the connection of pipe bends. According to the production process, it can be divided into: welding elbow, forged elbow, push elbow, casting elbow, butt welding elbow, etc. Malleable Iron LCC Long Compression Coupling is a kind of casting coupling, through melting, annealing, and then machined into pipe fittings. This material pipe fittings have good malleable castability, are relatively easy to process, and have a certain strength. Fittings are used in piping systems with working pressures between 1.6MPa to 2.5MPa. The connection of the piping system is connected by threads, and the threaded connections are sealed with pipe thread seal tape or sealant. There are three ways of surface treatment of pipe fittings: hot-dip galvanizing, electro-galvanizing and black. Galvanizing can make the pipe fittings have good anti-rust, anti-corrosion and other properties. Hot-dip galvanizing is done by placing the pipe filigents in the melted zinc liquid, and the thickness of the zinc layer is relatively thick, which can reach more than 70um. Electro galvanizing, also known as cold galvanizing, is to put the zinc block in the electrolyte, and then through electrostatic adsorption to make zinc ions attach to the surface of the pipe fittings, the thickness of the zinc layer is uniform, but the thickness of the zinc layer is thin, the thickness is more than 25um.

We do toughness test to compare our fittings with other brand's fittings. Our pipe fittings has better toughness, if you are interested, we can send you test video for your reference.Our pipe fittings threads are higher accuracy than other brand fittings. Our pipe fittings threads strictly compliance with EU standards at numbers of thread, according EN10242, for 1" nipple, the length thread is at least 14.5mm, the numbers of thread is at least 6.3, our pipe fittings fully comply EU standards, but other brand fitting has short length, and numbers aren't enough either.
Axes angle, turns of external thread and turns of internal thread are also higher 20% than EU standards.The axes of the screw thread is accurate to within ±0.5° of the specified angle according to ISO7-1,the axes of the screw thread accuracy of our fittings is ±0.3°,higher 40% than ISO7-1.
FM & UL
The black and galvanized fittings we produced are both UL (Underwriters Laboratories) and FM (Factory Mutual Insurance Company) approved. FM/UL has an independent testing facility where products are tested to make sure they meet the highest level of standards for safety and property loss prevention. No matter EN standard or ASME, as long as the product can pass the strict test in the laboratory, it can obtain FM/UL certificate.
