Where to Buy Schedule 80 Steel Pipe?

Where to Buy Schedule 80 Steel Pipe? Schedule 80 steel pipe is distinguished from Schedule 40 pipes by having thicker walls and being more robust, making it suitable for high-pressure applications, including industrial processes, hydraulic systems and underground piping.

Steel pipe wall thickness can be measured using the pipe scheduling system, which assigns each tube with an individual number that indicates its wall thickness and inner diameter. As its name implies, a larger number indicates thicker walls and decreased inner diameter.


Schedule 80 steel pipe is a high-grade product used across numerous industrial applications. It typically boasts thicker walls than Schedule 40 pipes, making them better suited to heavy chemical and pressure applications as well as increased durability against stress corrosion cracking.

Schedule 80 steel pipe can be costly depending on its size and material, yet still provide significant cost-cutting potential if required for extra durability or strength. While initially this investment might seem costly, over time you could save yourself both money and hassle by choosing to go this route.

There are various methods for identifying a pipe’s schedule. One straightforward way is by taking a closer look at its label – most schedule 80 pipes will feature gray or off-white coloring on them.

Checking packaging is also possible; sometimes there may even be an accurate schedule number displayed.

Schedule 80 pipes come in various thicknesses depending on their material and application, making it easier for you to find one suitable for your specific needs.

Additionally, you can locate a list of schedules on the manufacturer’s website or by conducting online searches. These lists provide an excellent opportunity to evaluate how strong and durable various schedules are.

When shopping for schedule 80 pipe, be sure to do your research. Different manufacturers provide discounts or coupons which could save money for you.

Although the exact price of a schedule 80 pipe will depend on its size, in general it will cost more than its Schedule 40 counterpart due to extra materials required to account for its thicker walls as well as any added colorants or treatments that come included with its purchase.

However, the extra strength that Schedule 80 pipes offer pays dividends over time; that is why they are frequently chosen in construction projects that demand additional strength.

If you need assistance selecting a pipe schedule for your project, be sure to speak with an experienced professional. They can ensure you select an optimal pipe that best meets your needs while making sure everything runs smoothly.


Durability of Schedule 80 steel pipe depends on several key elements. While this type of piping can be used in low-pressure applications like plumbing and irrigation systems, it also holds up well against higher pressure situations like industrial processes and hydraulic systems.

Durability in schedule 80 steel pipe applications depends upon wall thickness and pressure rating, with thicker walls able to withstand higher levels of pressure than thinner ones – hence its popularity for these purposes.

American National Standards Institute (ANSI) uses a formula to calculate a steel pipe’s schedule number; selecting an ideal schedule number for an application can prevent damage and ensure longer pipe lifespan.

Schedule 80 pipe is more durable than its schedule 40 counterpart for several reasons, including its thickness, notch resistance, tensile strength, impact resistance and abrasion resistance.

Applications that require extra strength and resilience would benefit greatly from its use, as it also resists corrosion more effectively than most materials.

Yet this extra durability comes at a cost; schedule 80 piping is more costly to produce due to more materials required in its creation, making it more costly for contractors who offer multiple schedules of piping to their customers.

As well as cost, other factors can impact the durability of schedule 80 steel pipe such as material selection, manufacturing methods and installation techniques.

Schedule 80 pipes typically feature thinner walls and smaller inside diameters than schedule 40 pipes at similar nominal pipe sizes, making installation more challenging and increasing weight significantly.

Heavy loads can be difficult to manage with improper installation of pipes; thus, it’s essential that you understand the difference between them in order to purchase high-quality items for your next project.

Corrosion resistance

Corrosion resistance of steel pipe is an important consideration for pipe and tube manufacturers as it dictates whether or not their material meets project needs.

Temperature, humidity, air impurities and wet times all play an integral part in corrosion. Different materials may be more vulnerable than others to corrosion; experts must have expert knowledge about each material in order to select an effective option for a task.

Schedule 80 pipe is an ideal combination of strength and corrosion resistance, making it suitable for various industrial applications, including aerospace, food & beverage production facilities, pressure containers, architectural designs, chemical processing equipment and cryogenics.

Schedule 80 pipes’ resistance to corrosion depends on their application and material selection; for instance, in marine environments a special anti-corrosion coating may need to be added for added protection against corrosion.

Additionally, the type of metal that’s used with the pipe also plays an integral part in its ability to resist corrosion. Some stainless steels are more corrosion-resistant than others and certain alloys are better suited for specific applications.

As such, different varieties of stainless steels exist to meet various applications and environments. One such material is 304 stainless, which offers excellent corrosion resistance in most environments.

316 stainless steel offers another alternative option, being more resistant to corrosion than its counterpart, 304. Therefore, this alloy is the better choice when projects may lead to rusting issues.

With so many stainless steels to choose from, it is crucial that you select one with appropriate properties for your project. If it requires high temperatures, opt for one with greater thermal diffusivity – this measure measures its ability to disperse heat evenly throughout its surface area.

No matter the stainless steel selected, proper welding techniques are key in maintaining its corrosion resistance. A welder must take great care with filler metal selection and cleanliness of the welded area; additionally, threading process must also protect both interior and exterior pipe surfaces against moisture intrusion and corrosion.


Schedule 80 steel pipe comes in various sizes to meet various applications. Common applications of schedule 80 pipe include industrial processes, hydraulic systems and underground piping as it’s built to withstand higher pressure than its counterpart, schedule 40 pipes.

Schedule 40 and 80 pipe are both widely utilized pipe schedules that each offer their own distinct advantages and disadvantages. The primary difference is that schedule 80 has thicker walls with smaller inside diameters than schedule 40; this makes it better suited for high pressure applications while schedule 40 is well suited to low-pressure systems like residential plumbing and irrigation systems.

Selecting an optimal pipe schedule can be challenging, so it is vital that you select one which best meets the needs of your project. Selecting an optimal schedule will help ensure your pipes remain safe and sturdy regardless of where they’re being installed.

The American National Standards Institute (ANSI) determines a steel pipe’s schedule number based on its nominal size and pressure rating.

Nominal pipe sizes in North America are standardized using Nominal Pipe Size (NPS) and Schedule standards. NPS defines the diameter of each pipe while Schedule indicates wall thickness standards.

If you need assistance in selecting the appropriate pipe schedule for your project, South Austin Metals’ experts are ready and willing to assist. They will explain how schedules are determined and help find one which best meets your requirements.

Other than your project schedule, many other factors need to be taken into account when choosing the appropriate steel pipe for your task. Most significantly is its pressure rating – higher pressure equals stronger pipe.

Pipe wall thickness also plays an integral part in its strength and durability; thinner walls increase cracking risk or corrosion damage more rapidly.

Pipe thickness increases its pressure capacity, so as schedule numbers increase so will its wall thickness and hence capacity to handle more pressures and stresses. As such, thicker pipes allow easier handling of wider range of pressures as well as increased stress.
