· If you look closely you will notice that 2.5" pipe has a slightly higher burst pressure rating than 2", oddly. Collapse Pressure. Collapse pressure (or PVC pipe crush strength) is the amount of outside pressure a pipe can take before it starts collapsing inwards. This is an important measurement when burying pipe for subterranean applications.

Contact usAn unplasticized PVC pipe, shown above, is quite rigid with high strength and good chemical resistance. These properties make it attractive for use in above or below ground plumbing applications. However, a very important change in property occurs as the temperature gets colder - the impact strength of PVC drastically changes for the worse.
Contact usCast iron pipe has long been the standard material for conveying water and sewage in municipal, utility and industrial piping systems. Ductile iron pipe, a product of advanced metallurgy, offers unique properties for conveying water under pressure, and other piping uses. It combines the physical strength of mild steel with the long life of gray cast iron.

Contact usThis is generally referred to as "crush strength" and "D-Load", however since flexible conduit reacts differently under a heavy weight load, these terms do not apply to PVC pipe. When a PVC pipe encounters external loading, its diameter will begin to deflect. If the pipe is buried in the right supportive soil conditions, the stiffness ...
Contact usThe strength, durability, and long service life of Ductile''s predecessor, Gray Cast Iron pipe, are widely recognized. The first official record ofGray Iron pipe installation was in 1455 in Siegerland, Germany.
Contact usDuctile cast iron has enhanced ductility, high impact strength, etc. Summary – Galvanized Pipe vs Ductile Cast Iron Galvanized pipe and ductile cast iron can be described as two types of iron. Galvanized pipes are pipes that are made by coating the iron surface with a zinc layer. This prevents the pipes from rusting.

Contact usExamine the pipe. Look at how weathered it is. Ductile pipe was first created in the 1950''s. It was first sold commercially in the 1960s, with most installations being done in the 1970s or later. If the pipe is older than that, then it is cast iron. Cast iron pipes have been around much longer than ductile pipes, which eventually replaced them.
