What is class 52 ductile iron pipe ?
Class 52 of the ductile iron pipe is quite identical to gray iron in chemical structure. The Class 52 ductile iron pipe can be used in various water supply projects, sewage, irrigation, drainage, and water pipelines. The Awwa c151 class 52 di pipes are also used in various acidic and corrosive environments, and they offer continuous performance due to their excellent chemical properties. The Ductile iron pipe class 52 has a pressure rating of 350 psi and thus, it can contain at least 900 psi water. The pipes are known for its long service life and it has high strength too.
These pipes are manufactured in accordance to the AWWA C-151 specification. Their dimensions and design can be customized according to the requirements specified by the client. These pipes are available in different material grades, like K8, K9, K10, L245, L290, Q235A, Q235B, Q345, X42, X46, X70, X80, X95. They are made according to ISO 2531 standard. These pipes come with different surface treatments like varnish, black paint, galvanization, etc., which enhances its appearance and also the corrosion resisting properties. The dimensions of the pipes are customizable according to specific application requirements.

Ductile iron class 52 vs class 53
The ductile iron class 52 pipes of the same nominal diameter as class 53 pipe can withstand higher pressure. This is because the nominal thickness for each pipe size is higher for class 53 compared to class 52.
Find trustworthy stockists of 4 inch di class 52 pipe in Middle East countries, and look at how much pressure can take this pipe.
How much pressure can take class 52 di pipe ?
The Class 52 di pipe comes with a pressure rating of 350 psi. Thus, they are sufficient for containing at least 900 psi water, which is dependent on the joint restraint. The ultimate containment capability for the internal pressure of the given pipe size and wall thickness can be calculated with the help of the following formula:
t= PiD / 2S,
Wherein t is the computed min net thickness in inches
Pi is the internal pressure measured in psi
D is the nominal outer pipe diameter in inches
S is the min yield strength for ductile iron pipe

Why are awwa standard important for ductile iron class 52 pipe ?
The AWWA standards for the Class 52 ductile iron pipe specifications cover the usage of polyethylene encasement for protecting the ductile iron pipes against corrosion. It also covers other minimum manufacturing requirements which are used in potable water, reclaimed and wastewater applications. It also covers for some tests of the pipe and that they should meet some minimum requirements. The standard establishes three tests for the quality and the durability of the pipe. For example, they should be subjected to a hydrostatic test of not less than 500 psi. Also, the physical properties of the metal must meet the min tensile strength of 60,000 psi and yield strength of 42,000 psi, at a 10% elongation which is required for durability. The AWWA standard also focuses on the internal lining of the pipe with cement so as to prevent tuberculation. Also, rubber gaskets should be placed between the segments of the pipe at the joint and compressed, which will help to make a water-tight seal.
