Firstly, caps are a type of malleable iron pipe fitting that are used to seal the end of a pipe. Malleable iron is a type of cast iron that has been treated with heat to improve its strength and durability.
Secondly, caps are typically threaded on the inside and are designed to screw onto the end of a pipe, providing a tight seal to prevent leaks. They are commonly used in plumbing and gas line applications, as well as for industrial piping systems.
Benefits About Caps Malleable Iron Pipe Fittings
Caps Malleable Iron Pipe Fittings are threaded components designed to join and seal steel pipe. Caps, unions, elbows, tees and other fittings are commonly available in malleable iron. These fittings offer several advantages for plumbing and industrial piping installations.
Although not stainless, malleable iron develops a patina that helps prevent corrosion. Fittings can also be galvanized or coated for extra corrosion protection in harsh environments.
Malleable iron fittings are made of high-carbon malleable iron that is strong, ductile and able to withstand high pressures. They can last a long time with minimal leakage or damage.
Malleable iron fittings can join steel, galvanized steel, wrought iron and even copper pipe. They provide a durable connection between multiple piping materials.
Key Tips For Using Malleable Iron Caps
Use a pipe threader or dies to cut and shape threads on the pipe ends to the correct taper and dimensions before assembling a fitting. Rough or uneven threads will not seal properly.
Screw the fitting onto the pipe hand-tight before tightening with a pipe wrench. This allows you to keep turning ifyou cross-thread the joint.
Apply 2-3 wraps of plumbing thread tape or apply sealant thread sealant to the male threads before screwing on a fitting.
