Overview of Schedule 80 Carbon Steel Pipe
Schedule 80 carbon steel pipe refers to pipes with Schedule 80 characteristics, whose strength and toughness are determined by the composition of carbon steel. Different grades of carbon steel pipe determine its performance in pressure capacity, and Schedule 80 steel pipe represents a certain pressure carrying capacity. In order to standardize the pressure capacity of pipes, a "Schedule Scale" system is used, where the Schedule Scale ranges from 5 to 160. The higher the number, the greater the pressure the pipe can withstand.
Pipe specifications are usually marked with "Sch", a method defined by the ASME B36.10 standard. Schedule 80 steel pipe is not a single wall thickness, but a collection of wall thicknesses. The inner diameter of the pipe is critical to the transportation of fluids and gases, and different specifications represent different wall thicknesses at the same diameter.
Schedule 80 Carbon Steel Pipe Specifications and Dimensions
So the Schedule 80 Pipe Dimensions would be in half way through the spectrum. The nominal bore sizes range from 1/8 inches through 6 inches and the internal and external diameters vary. This in turn affects the wall thickness to vary from 0.095mm to 0.432mm. So the Schedule 80 Pipe Pressure Rating depends on all of these factors; the wall thickness, the diameter and the material grade. The stronger materials don’t need to have thicker walls to be in schedule 80. The Schedule 80 Pipe Thickness In Mm ranges only from 0.095mm to 0.432. The applications of the carbon steels pipes are in the less corrosive, high toughness and high wear and tear applications. The Schedule 80 Pipe Weight differs based on the grade, wall thickness, diameter and length of the pipe. Please contact us for more information and pricings.

Application of Schedule 80 Carbon Steel Pipe
Schedule 80
carbon steel pipe has a wide range of applications in many fields due to its excellent durability and strength:
(1) Industrial applications
In industrial environments, Schedule 80 carbon steel pipe is often used for fluid and gas transportation under high pressure. The pipe is widely used in chemical processing plants, refineries and power generation facilities due to its rugged construction and ability to withstand harsh environmental conditions. Schedule 80 pipe is also commonly used in HVAC systems, fire protection systems and industrial water treatment processes due to its reliability and long life.
(2) Commercial Uses
The commercial sector utilizes the versatility of Schedule 80 carbon steel pipe to meet a variety of needs, including plumbing and drainage systems, structural support, and mechanical infrastructure. Suitable for commercial buildings, shopping centers and sports facilities, the pipe's wear resistance and durability make it an affordable choice.
(3) Residential Applications
In residential construction, Schedule 80 carbon steel pipe is used for piping solutions that require durability and longevity. This includes underground water lines, natural gas distribution and sewage systems. Its resistance to external pressure and environmental factors makes it an excellent performer in ensuring the safety and functionality of homes.
Benefits of Schedule 80 Carbon Steel Pipe
Why you need to know SCH 80 and its importance:
In construction, the numerical requirements have always been high. Because the accuracy of the numerical values has a great impact on the success of the project. Especially in foundation construction, the stability of the building may be problematic due to a numerical deviation, and it may collapse or tilt without knowing when. Therefore, construction workers must pay attention to the numerical values and be cautious. Next, let me introduce to you the SCH 80, which has been discussed a lot recently.
SCH 80 represents the wall thickness grade of the American standard seamless steel pipe. The wall thickness corresponding to different numbers will also be different. In the industry, this method is often used to replace numerical values, making it easier for everyone to record and use. When designing for some constructions, such accurate values are needed to enable the design to be successfully constructed. If the values are inaccurate, there may be a large gap and lead to failure.
In addition to SCH, which represents the wall thickness of American standard steel pipes, there are also other pronouns such as DN and NB that describe the diameter of steel pipes. DN represents the nominal diameter of the steel pipe in mm, and NB represents the British standard in imperial units.
We will use different ways to express it for different application situations.
SCH 80 means XS thickened pipe with pressure wall thickness less than DN200mm.
The method of expressing wall thickness by the inner diameter of carbon steel reducers stipulated by MSS and ANSI in the United States divides the wall thickness of pipes into three types:
1. Standard weight pipe is represented by STD, which is a carbon steel reducer with an inner diameter
2. The thickened pipe is represented by XS, which is a carbon steel reducer with an inner diameter 3. Extra thick pipes are represented by XXS, which are carbon steel reducers with an inner diameter
Extended information:
Domestic carbon steel reducers comply with American pipe standards: Sch5s, Sch10s, Sch10, Sch20, Sch30, Sch40s, STD, Sch40, Sch60, Sch80s, XS; Sch80, SCH100, Sch120, Sch140, Sch160, XXS; among them the most commonly used ones are two types: STD and XS.
The internationally accepted pipe flange standards can be summarized into two different and non-interchangeable pipe flange systems: one is the European pipe flange system represented by Germany; the other is the American pipe flange system represented by the United States.
Summary
Schedule 80 carbon steel pipe is the pipe of choice for a wide range of applications due to its superior strength, durability, and versatility. Whether in industrial, high-pressure applications or in commercial and residential construction, Schedule 80 carbon steel pipe provides a reliable solution. With proper treatment and coating, this pipe is able to perform well in a variety of environmental conditions. For applications that require high pressure and high durability, Schedule 80 carbon steel pipe is undoubtedly a quality option worth considering.
