What is the manufacturing process of carbon steel ERW pipe?

• The manufacturing process of Electric Resistance Welded pipes begin with the preparation of steel coils- they are then uncoiled and fed into the ERW mill machine.
• The edges of the strip are formed into a circular shape- the strip is gradually passed through a series of rollers to achieve the desired pipe diameter.
• The edges are then heated and fused together using electric resistance welding- it creates a strong and continuous welded seam.
• Finally, the Carbon Steel ERW Pipe is cut to the required length and undergoes various finishing processes before being ready for use.

In which application we should not use carbon steel welded pipe?

There are certain applications where the use of CS ERW Pipes may not be suitable- like in environments with high levels of corrosive substances such as highly acidic or alkaline solutions. Carbon Steel Welded Pipe without proper coatings or linings might be susceptible to corrosion in such aggressive environments- in these cases, alternative materials like stainless steel or corrosion-resistant alloys are typically preferred to ensure long-term durability and resistance to corrosion. It is important to assess the specific operating conditions and consult with experts to determine the most suitable pipe material for each application.

What is the difference between carbon steel lsaw and ssaw pipes?

The main difference between carbon steel LSAW (Longitudinal Submerged Arc Welding) and SSAW (Spiral Submerged Arc Welding) pipes is in the welding process and shape of the pipe. Longitudinal Carbon Steel SAW Pipes are straight with a longitudinal weld seam, while SSAW pipes have a spiral-shaped weld seam.

LSAW pipes are typically used for larger diameter and thicker wall applications, while Carbon Steel SSAW Pipes are used for smaller diameter and thinner wall applications. The choice between the two depends on factors such as the project requirements, pipe dimensions and intended application.

What causes Carbon Steel spiral welded pipes to crack?

One primary cause for the Carbon Steel spiral welded pipe to crack is the presence of high-stress concentrations- it can occur due to improper welding techniques or design flaws.

Inadequate heat treatment during the manufacturing process can also lead to increased susceptibility to cracking.

Environmental factors like exposure to corrosive substances or extreme temperatures, can further exacerbate cracking- it is crucial to ensure proper welding procedures, appropriate heat treatment, and consider the operating conditions to minimize the risk of cracking in Carbon Steel EFW Pipe.

How price vary of CS Welded Pipe based on thickness?

The price of CS Welded Pipes can vary based on the thickness of the pipe. Generally, thicker pipes require more raw materials and incur higher production costs- this results in a higher price. Thicker pipes also require more welding time and may involve additional processing steps. Therefore, as the thickness of the Carbon Steel DSAW Pipe increases, the price tends to rise.

Which is best welding procedure to weld Carbon Steel LSAW Pipes?

When welding Carbon Steel LSAW Pipes, the best procedure depends on factors like the pipe material grade, wall thickness and intended application. Generally, the submerged arc welding (SAW) process is used for LSAW pipes due to its high productivity and efficiency- it involves feeding a continuous wire electrode into the weld zone while shielding the arc with a granular flux. This process provides deep penetration and produces strong and high-quality welds.
