Different Types of Pipe

tubes-pipes-geometric-abstract-81628Steel Dragon Tools pipe threading machines can cut, thread, and ream a variety of different types of pipe with the right die head and dies. Some of the different types of pipe available on the market includes black iron, galvanized steel, stainless steel, copper, and plastic. Each pipe material has different uses and qualities.


Black iron pipe is made from mild steel. Black iron pipe is susceptible to corrosion when exposed to alkaline or acidic water. Black iron pipe is typically used for low-pressure and low-heat applications with gas or steam but is not suitable for potable water.


Cast iron pipe is manufactured with molds and is mostly used for sewage and waste removal. Cast iron pipe will corrode when in contact with carbonic or sulfuric acids. Cast iron pipe can be found in the sewage systems of many homes due to its durability and longevity. This type of pipe is popular for use in waste removal before of its thickness. The pipe’s density helps to muffle the sound of water and waste moving through it, resulting in a quieter home.


Galvanized iron pipe, also known as galvanized steel pipe, is steel pipe with a protective zinc coating. The zinc layer prevents rust and corrosion for approximately 40 years. Once the layer of zinc has been worn away, corrosion and deposits of salt and lime will eventually block the pipe. Galvanized pipe was used for potable water delivery but has been replaced with the more resistant copper and easier-to-handle PVC. Thanks to its anti-corrosion properties, durability, and relatively low cost, galvanized pipe is still popular for use outdoors in irrigation or in large construction projects where the amount of copper pipe needed might be cost prohibitive.


Stainless steel pipe is made with different alloys for use across many industries including food, aircraft and aerospace, nuclear energy, military, and medical applications. Stainless steel pipe is highly regarded for its low maintenance, corrosion resistance, hygienic properties, ease of fabrication, durability, and recyclability. Some types of stainless steel pipe are highly acid resistant and are typically found in chemical plants or for use in food processing.


Copper pipe is durable and corrosion resistant. This type of pipe is easy to handle and install but can be expensive. Copper pipe is typically used for potable water delivery and refrigerant lines in air conditioning systems. Copper pipe can also be used for gas delivery systems, both industrial and medical.


Polyvinyl chloride pipe (PVC) is a versatile material that comes in several chemical variations for different uses. This pipe can be used for pressure and non-pressure applications including potable water service, radiant floor heating, drains, waste removal, venting, irrigation, and ice melting. PVC pipe is inexpensive, easy to handle, and resistant to most household chemicals. PVC pipe does have a low resistance to heat and will expand rapidly when heated. PVC also has a lower pressure rating and crush resistance when compared to most metal pipe.
