Pipe sizes can be confusing because the terminology may relate to historical dimensions. For example, a half-inch iron pipe does not have any dimension that is a half inch. Initially, a half inch pipe did have an inner diameter of 1 ⁄ 2 inch (13 mm)—but it also had thick walls. inch (13 mm)—but it also had thick walls.

For many decades sizing orifices for Air Release Valves has been a mystery. Air entrapped in pipelines is an invisible culprit and no quantitative means exist to determine the precise amount of entrapped air in a flooded transmission pipeline.
A commitment to using only the highest standard of raw materials and the latest manufacturing technology has established Vinidex with a reputation as a quality supplier of polyethylene (PE) pipes. Sizes range from 16mm to 1200mm in diameter. The flexibility of Puhui Pipe manufacturer in China
Fire fighting pipe is a type of normal carbon HDPE pipe used to convey fire suppression agent such as water or gas. Usually it is red in color. But light-wall pipes have a galvanized exterior of a silvery appearance. Installation of red HDPE pipe is limited to wet pipe Puhui Pipe manufacturer in China
It is uncertain when the first crude oil pipeline was built. Credit for the development of pipeline transport is disputed,  with competing claims for Vladimir Shukhov and the Branobel hdpe pipes in the late 19th century, and the Oil Transport Association, which first constructed a 2-inch (51 mm) wrought iron pipeline over a 6-mile (9.7 km) track from an oil field in Pennsylvania Puhui Pipe manufacturer in China

Surge pressures in HDPE pipe are significantly lower than in DI pipe and lower than PVC pipe due to the lower value of dynamic modulus for HDPE. For example, in a typical 8" line a velocity change of 5 fps would cause a 51 psi surge in HDPE DR17 pipe, a 87 psi surge in PVC DR18 pipe, and a 262 psi surge in DI Class 350 lined pipe.
The chemical compatibility of LDPE and HDPE on this chart is tested at 20 C: and 50 C: for 7 days and 30 days (if applicable) with constant exposure. LDPE & HDPE resistance listed by chemical 1.4-dioxane
A good quality HDPE pipe exhibits the properties of a construction material when compared with other conventional piping materials. As discussed above, HDPE pipes have excellent physical properties that are ideal for many industrial appliions.
