Max steels are the largest firm manufacturing the high-quality cu 70/30 pipe fittings. We are exporting these pipe fittings all over the world respect to national and international standards. These are fabricated in a variety of shapes such as the elbow, reducer, tee, cross, stub bends and more. We are taking small and bulk orders of copper pipe fittings and delivering it within a week.
These pipe fittings can be exposed to high-temperature applications without a deformation. These are made up from the composition of copper and nickel fittings in the 70/30 ratio. It has low creep rates under heavy forces. The grade has a high melting point so that is suitable for heating applications.
The grade is austenitic in nature. Pipe fittings come with tolerance and allowance for the different type of industrial pipe fittings. The cu alloy is magnetic and non-magnetic in nature. This serves excellent service towards corrosion and abrasion resistance.
Pipe fittings are processed from high-grade crude materials under the rolls of latest machines. The heat treatment process like annealing and tempering increases the stability against the heat. Moreover, it is protected from the industrial coatings of satin and bright black polish this prevents from rusting and oxidations.
Several testing procedures are conducted to provide high-grade material to clients. The tests are as follows mechanical test, tensile test, PMI test, intergranular corrosion test, destructive- non-destructive test, radiographic tests and other tests on the demands of the clients.
Cu 70/30 pipe fittings are prominent for industrial pipe fittings applications.
