What is the difference between pipe vs tube?

What is the difference between pipe vs tube? A pipe is a round tubular to transport or distribute fluids and gases. Steel pipes are designated by a nominal size value (NPS or DN), which represent a rough indication of their inside diameter and fluid conveyance capacity. A tube is a round, rectangular, squared or oval hollow section measured by outside diameter (“OD”) and wall thickness (“WT”), expressed in inches or millimeters.  Pipes are used for conveying fluids and gases; tubes are used to manufacturing pressure equipment (tubing) and for mechanical applications. PIPE INSIDE DIAMETER The word “steel pipe” refers to round […]

What are the risks of natural gas pipeline construction?

Abstract: The construction of long-distance transportation natural gas pipeline system is to achieve the purpose of long-distance pipeline transportation of natural gas, so that users along the line can obtain the required gas volume to meet the needs of users.       The construction of long-distance transportation natural gas pipeline system is to achieve the purpose of long-distance pipeline transportation of natural gas, so that users along the line can obtain the required gas volume to meet the needs of users. The procedures for pipeline construction are complicated. Long-distance pipeline systems are generally buried pipelines. Pipe trenches need to be dug. For […]

Difference Between SCH 40 and SCH 80 Steel pipe

“Schedule 40” and “Schedule 80” refer to the thickness of the walls of pipes. “Schedule” is the standard of wall thickness that has been adopted by the American National Standards Institute. As per the Institute, the thickness of wall pipes varies from Schedule 10, Schedule 40, Schedule 80, and Schedule 160. Pipes with Schedule 40 come with standard weight, and pipes with schedule 80 come with extra strength. The materials used for making Schedule 40 and Schedule 80 come from the same material. Schedule 80 pipes have a thicker wall than Schedule 40 pipes. As such, Schedule 80 pipes are […]
