Difference Between Welded Steel Pipes And Seamless Pipe in Pakistan

Seamless Pipe in Pakistan is one of the most versatile alloys used in manufacturing and manufacturing, and SS pipes are used in a variety of industries. Seamless steel pipe and welded steel pipe are the two most common types of stainless steel pipe.

Seamless Pipe in Pakistan

The Seamless Pipe in Pakistan is made of spherical steel plates or solid rods called “blocks” and are heat treated and shaped like rods with holes to form hollow tubes or sleeves. Made of cylinder steel. After heating the tape to a high temperature, insert the probe into the cylinder to make a hole. A hollow, seamless round tube. Seamless steel pipe is made of carbon steel, alloy steel, stainless steel alloy. These pipes are known to be superior to welded pipes. It is built using really mechanically strong monolithic steel bars.

Welded Steel Pipes

Welded pipes are a type of pipe with a steel pipe joint on the surface. This is caused by bending the steel belt or steel sheet material into a sphere, square or other shape, then welded in place. Plate winders and benders are used to round or round flat bars, sheets and plates. Then use high power to weld the pipe with or without filler. Welded pipes come in a variety of sizes and can be long pipes. Welded pipes made of 310S stainless steel are commonly used to transport large amounts of water, oil, or gas.

The differences between Seamless Pipe in Pakistan and welded pipes are as follows:  

Appearance

Steel bars are used as the raw material for seamless steel pipes. The hot rolling process cannot remove defects on the outer surface of the bar. After the product is finished, it needs to be scrubbed. Defects can only be partially removed during the process of lowering the wall. On the contrary, welded steel pipes are made from hot rolled steel. Also, the surface quality of the coil is exactly the same as the surface quality of the pipe. Hot rolled steel has a high quality surface. Welded steel pipes have much higher surface quality than Seamless Pipe in Pakistan.

Casting process

Seamless Pipe in Pakistan can be made only once by the rolling process. Welded steel pipes are made of steel plate or steel plate and are made through various bending and welding processes.

Performance and ease of use

Seamless steel pipes are widely used in the boiler and high pressure equipment industry due to their higher strength and pressure than ERW welded steel pipes. Welded steel pipes are often a weakness. Quality affects overall performance.

Welded steel pipes can withstand 20% lower working pressure than seamless steel pipes. Reliable 316 stainless steel seamless tubing is also used at a high level. All industrial pipelines are made of seamless pipes due to the high thermal, chemical and mechanical loads. The budget and pressure for pipe use is very low.

Corrosion

Until the seamless steel pipe is exposed to a highly corrosive environment that shows no signs of corrosion. On the other hand, the welded area of ​​the weld pipe is vulnerable to corrosion attacks. Therefore, there are various weaknesses because the connection area is considered monolithic. Low wear resistance and a larger dimension of distribute seamless pipe manufacturers in Pakistan. Eliminates of these problems and guarantees excellent corrosion resistance.

Advantages of seamless pipe:

  • Energy.
  • Corrosion resistance
  • Strong against high pressure.
  • Durability
  • Higher material purity

Advantages of welded stainless steel pipe:

  • Worth it
  • Faster production
  • Easy to customize
  • Consistent focus
  • Top bear

Welded steel pipes are widely used in boilers, automobiles, shipbuilding, furniture, agricultural machinery, scaffolding, wire pipes, overhead racks, containers and other applications. Seamless Pipe in Pakistan are used in seawater Gas and liquid transport Chemical lines Oil and gas flow lines Chemical and heat treatment plants
