Polishing Cold rolling EFW ASTM B474 UNS N02201 Alloy 201 pipe

1 Overview:

Commercially pure or low-alloy nickel has characteristics that are useful in several fields, notably chemical processing and electronics. Nickel is highly resistant to various reducing chemicals and is unexcelled in resistance to caustic alkalies. Compared with nickel alloys, commercially pure nickel has high electrical and thermal conductivity. It also has a high Curie temperature and good magnetostrictive properties. Annealed nickel has a low hardness and good ductility and malleability. Those attributes, combined with good weldability, make the metal highly fabricable. Nickel has a relatively low work-hardening rate, but it can be cold worked to moderately high strength levels while maintaining ductility.

Nickel 200 (UNS N02200/W.Nr. 2.4060 & 2.4066) is commercially pure (99.6%) wrought nickel. It has good mechanical properties and excellent resistance to many corrosive environments. Other useful features of the alloy are its magnetic and magnetostrictive properties, high thermal and electrical conductivities, low gas content and low vapor pressure. Chemical composition is shown in Table 1. The corrosion resistance of Nickel 200 makes it particularly useful for maintaining product purity in the handling of foods, synthetic fibers, and caustic alkalies; and also in structural applications where resistance to corrosion is a prime consideration. Other applications include chemical shipping drums, electrical and electronic parts, aerospace and missile components.

Commercially pure wrought Nickel with good mechanical properties over a wide range of temperature and excellent resistance to many corrosives, in particular hydroxides.

Application field:

Many different industries utilize Ni 200, but it is especially useful to those who are looking to maintain the purity of their products. This includes:

Food handling

Manufacturing synthetic fibers

Caustic alkalis

Structural application that demand corrosion resistance

Characteristics

Ni 200 can be hot rolled into practically any shape, and it also responds well cold forming, and machining, as long as established practices are followed. It is also accepts most conventional welding, brazing, and soldering processes.

What is the Difference Between Pipe and Tube?

One of the most frequent questions we get from customers is “What’s the difference between pipe and tube”? Although pipes and tubes may look similar, they are in fact quite different in nomenclature and sizing. Remember that pipes and tubes are rarely interchangeable.

The difference between pipe and tube include:

• Shape

• Measurement

• Telescoping Abilities

• Rigidity

• Applications

• Metal Types

• Size

• Strength

Shape

Pipes are always round in shape. Tubes can be square, rectangular or round, as shown in the image to the right.

Measurement

Pipes are only provided with an inside (nominal) diameter and a “schedule” (which means wall thickness). There’s an easy way to remember this: since pipe is used to transfer fluids or gas, the size of the opening through which the fluids or gas can pass through is probably more important to you than the outer dimensions of the pipe. Tube measurements, on the other hand, are provided as an outside diameter and set ranges of wall thickness.

Telescoping Abilities

Tube can be telescoped. Remember to account for the flash weld inside the tube. Pipe, on the other hand, does not have a flash weld. DOM (Drawn over Mandrel) Tube is the best material for telescoping because the inside flash weld has been removed.

Rigidity

Although copper and brass tubes can be shaped relatively easily, tubes are are typically rigid. Pipes, on the other hand, are invariably rigid and cannot be shaped without special equipment.

Applications

Only pipes are pressure rated and intended to be used for the transference of fluids or gas. Tubes, on the other hand, are used in structural applications.

Metal Types

Tube is available in hot rolled steel and cold rolled steel. Pipe is typically black steel (hot rolled). Both items can be galvanized.

Size

Pipe is typically available in larger sizes than tube.

Strength

Tube is stronger than pipe.
