Aluminum is a strong, corrosion resistant, lightweight pipe that is very versatile and has a wide range of applications. It works very well for compressed air systems, and is widely used for its ability to be welded.
Nickel-based alloys offer high strength, as well as high temperature and heat resistance. It is usually made from pure wrought nickel, and has good mechanical properties with very high resistance to many corrosives. It is commonly used to maintain product purity in handling foods.
Chromium is a seamless ferritic Alloy-Steel pipe for high temperature service. It enhances the corrosion resistance of steel, and inhibits pitting. It is the essential constituent of stainless steel. It is remarkable for its magnetic properties, and is the only elemental solid which shows antiferromagnetic ordering at room temperature.
Copper tubing is most often used for the supply of hot and cold tap water, medical gas, and as a refrigerant line in HVAC systems. The three most common types are Type K (thickest), Type L (medium), and Type M (thinnest). Types K, L & M are all made in both rigid and flexible forms. It can be joined using flare connection, solder, compression connection, or press.
Hastelloy is a nickel-based alloy that exhibits some of the highest resistance to corrosion. It is perfect for a wide range of chemical applications that would oxidize other metals. It contains molybdenum and chromium to help round out its profile, and is widely regarded as one of the world’s toughest alloys.
Inconel pipe is a high strength, nickel-based alloy. It exhibits excellent corrosion resistance, oxidation resistance, and toughness. It has a very high fatigue strength, is non-magnetic, and offers an operational temperature range from cryogenic to 2,000deg F. It is often used in process heaters and high purity eater systems in nuclear reactors, and is an acceptable material for heat exchanger tubing and flowing sea water.
Molybdenum tubing is the most commonly used refractory metal, being the least expensive. It is an ideal material for use in x-ray anodes and CT imaging. It can be used effectively up to 1800deg F. It has the third highest melting-point of any element, and is commonly used to make steel, high-strength and super alloys.
Monel pipe is mostly composed of nickel and copper. It is stronger than pure nickel, and is resistant to most corroding agents. It is quite expensive, and therefore its use is typically limited to applications where it cannot be replaced with something cheaper. It is three times as expensive as carbon steel.
Stainless Steel pipe comes in a variety of grades; 304, 316 and 347. Stainless steel has great corrosion resistance to chemical corrosives as well as industrial atmospheres. It has good formability and can be readily welded by all common methods. It is commonly used in the fuel and petroleum industry, breweries, food processing plants, and for waste water processing.
Titanium pipe and tubing is used in a wide-range of applications because of its superior strength-to-weight ratio and corrosion resistance. It is very easy to use in alloys, and because of this it has found its way into many industries, from power generation to chemical and industrial processing. Titanium pipe is much more expensive than carbon steel, but it is considered to be quite cost effective because of how long it lasts.
