Low Pressure Fluid Transportation with Large Diameter Electric Welded Steel Pipes
Large diameter electric welded steel pipes are commonly used in low pressure fluid transportation systems. This type of pipe is less expensive, has greater flexibility and is easier to install than other types of pipes, making it an attractive option for many industries.
Large diameter electric welded steel pipes are generally manufactured using grade A or grade B steel. Both grades are suitable for the demands of low pressure fluid transportation systems. Grade A steel is a relatively low-carbon steel with a higher level of specified mechanical properties and greater corrosion resistance than grade B. This type of steel is more common and therefore more cost effective.
The large diameter electric welded steel pipes are usually made to the diameter – nominal diameter ratio of (DN/ND). This ratio is used to define the actual size of the pipe rather than seeking its actual outside diameter. The standard DN/ND ratio of these pipes is 6, meaning that the actual diameter of the pipe is six times its nominal diameter. Generally, the size of the pipe is capped at DN/ND 8.
In order to withstand the demands of low pressure fluid transportation systems, the large diameter electric welded steel pipes must also meet a series of criteria. This includes pipes with a wall thickness that is suitable for low pressure, as well as a surface condition and chemical composition that allows for efficient flow of the fluid. The pipes should also be resistant to corrosion and have an internal surface which has not been altered in any way.
The benefits of using large diameter electric welded steel pipes in low pressure transportation systems include the following:
Cost – Large diameter electric welded steel pipes are generally much more cost-effective than their counterparts in other piping systems, making them an attractive option for many businesses.
Durability – Unlike other materials, steel pipes are extremely durable and can withstand large amounts of pressure and vibrations over time. This makes them ideal for use in low pressure transportation systems.
Ease of installation – Installing large diameter electric welded steel pipes is relatively easy, requiring minimal tools and minimal labour. This reduces the overall cost of the installation process.
The large diameter electric welded steel pipes in compliance with GB/T 14980-94 are highly suitable for use in low pressure fluid transportation systems. This type of pipe is much less expensive, more durable and easier to install than other types of pipes, making it an attractive option for many industrial processes.
