Out Diameter

168.3mm-2050mm

Wall Thickness

6mm-25mm according to the pressure.

To meet the requirements of internal design pressure, the pipe wall thickness is determined by using the following
formula:  t=PD/2S
Where:
t = design nominal wall thickness for the specified internal design pressures.
Thickness and weight tolerances for pipe shall be governed by the
requirements of the specification to which the plates or sheets are ordered (in. [mm])
P = internal design pressure (psi [kPa])—specified by the purchaser
D = outside diameter of the steel pipe cylinder (in. [mm])

S = design stress (psi [kPa]), not to exceed the purchaserspecified
percentage of the minimum yield point of the steel selected by the manufacturer .

Length

5.8m-20m,or as customer’s requirements.

Technique

SAW welding

Application

This standard covers the requirements for steel water pipe for use
in water transmission and distribution under normal circumstances. It is the responsibility of the purchaser for each project to determine if any unusual circumstances related to the project require additional provisions that are not included in the standard. Such special conditions might affect design, manufacture, quality control, corrosion protection, or handling requirements
