Seamless steel pipe D114

Seamless steel pipe D114 Hot products at Tiger steel here!

Can you believe it? we just imported 2 containers 2 weeks ago, but until today, there is not 1 piece left in stock.

Feeling curious, so today I decided to find out the reason.

The new one contacted a few customers to ask how. When I heard the answer, I was surprised too.

The customers said that: The project is by your side, At first, the selection of welded pipe 114 was calculated, but then recalculated, and the bearing capacity was insufficient. Should turn to choose Seamless pipe.

By the way, Tiger Steel also introduced you to know more about it.

First, find out the outstanding characteristics of Seamless steel pipe D114

Reality during testing shows:
Seamless steel pipe D114 has much better pressure resistance than welded 114 pipes. The reason lies in the weld of the welded steel pipe. When Tiger Steel tested the welded pipe, the result was that the pressure withstand was lower at the welding point than at other points of the steel pipe.
If you do not have much time to verify, test the product. It is possible to calculate through the formula for calculating the working pressure of the pipeline. Rest assured, the Tiger Steel formula mentioned below is completely accurate and is certified by many scientific societies around the world.

That’s Peter Barlow’s formula:

Pipeline working pressure
In there:
  • P a = maximum allowable pressure (psi)
  • S y = minimum yield stress (psi)
  • F d = design coefficient
  • F e = longitudinal weld coefficient – Table 841.115A of ASME B31.8-2012
  • F t = temperature reduction coefficient

Typical design coefficients Fd: (QCVN 01:2016/BCT)

  • Liquid pipeline: 0.72
  • Gas pipeline – type 1 zone 1: 0.8
  • Gas pipeline – type 1, zone 2: 0.72
  • Gas pipes – type 2: 0.60
  • Gas pipes – type 3: 0.50
  • Gas pipes – type 4: 0.40
The second point is the cost: If you consider the total cost from the time of purchase to the maintenance process later. It is definitely more profitable to buy Seamless steel pipes.
However, this point still depends a lot on the actual work.
