Stainless Steel 304 Pipe
Categorised under a chemical engineering process, the refining of petrochemicals includes a set of procedures that transform crude oil to usable end products such as liquefied petroleum gas or LPG, kerosene, gasoline or petrol, jet fuel, diesel oil and fuel oils. An alloy that serves this application with par excellence is grade 304.
Hence, the petrochemical industry is one of the major endorsers of SS 304 Pipes. Due to the many steps involved in refining petrochemicals, the SS 304 welded pipes is often exposed to innumerable chemical processes such as distillation, hydrodesulfurization, alkylation, isomerization to name a few. At every step, the SS 304 efw pipe not only have to transport the raw material, but they also have to convey the refined product that contains additives.
This transportation of fuel causes a lot of stresses to the pipes, which is why we recommend our clients to check out the SS 304 erw pipes weight chart here for reference. Moreover, the flow of the refined product is also dependent on the ASME SA312 grade 304 pipes size. In comparison to the ordinarily used carbon steel pipes, the cold worked SS 304 seamless pipes has a much tougher disposition while demonstrating higher tensile strength properties. Therefore the ASTM A312 tp 304 seamless pipes is a well favoured product across global refineries. Click here to learn more about the aisi 304 pipe price.

How to get the weight of 304 round pipe and square pipe?
In order to calculate the weight of round pipes, one would require the following dimensions i.e. - outer diameter or OD in mm along with wall thickness or as referred to as W.Thick in mm as well. Using the below mentioned equations, one could calculate the weight of the pipe in meters or in feet.
OD (in mm) – W.Thick (in mm) X W.Thick (in mm) X 0.0248 = Weight Per Metre
OD ( mm) – W.Thick (in mm) X W.Thick (in mm) X 0.00756 = Weight Per Foot
Square shaped pipes have all four sides in an equal proportion formed at a 90 degree angle. Similarly, calculating the weight of grade 304 square pipe could be done by the method above by substituting the outer diameter as is the case of a round pipe by the height or width of the square. Hence, the modification of the formulae would be as follows -
Height ( in mm) – W.Thick (in mm) X W.Thick (in mm) X 0.0248 = Weight Per Metre
Height ( in mm) – W.Thick (in mm) X W.Thick (in mm) X 0.00756 = Weight Per Foot
