Copper nickel pipe types vary by composition and diameter. There are different grades, standards and pressure classes of these pipes. There are two different measuring systems as well. The imperial system uses the inches and foot units for measurements. But in many countries the centimeter, meter system is used as the standard. This is called the metric measurement system. The advantage of the metric measurement system is that it is universal. So any supplier from any country or locale could communicate with any customer from any other part of the world in the same language. The copper nickel pipe dimensions have to be communicated accurately before production. There are different grades of the copper nickel material such as the 90/10 or 70/30 material.
These correspond to the different compositions and their different quantities in the composition. However, all pipes have to be measured for diameter, wall thickness and length. The copper nickel tubing can therefore be produced in the correct dimensions given the correct measurements. Since the material is highly thermally expansive, it has to be correctly calculated before application. It is the same reason why welding and other methods that involve heating should be administered carefully onto these pipes. If not applied carefully, these could lead to deformation of joints. The 90/10 copper nickel alloy is also called the cuni90/10 in short. The prices of cuni 90/10 pipe and fittings can vary according to the availability, supplier storage capacity, transportation means, application requirements, wall thickness, diameter and other market factors as well.
