Welding terminology

T = Time
P = Pressure
B = Bead size

Pipe terminology

ND = Nominal Diameter
ID = Internal Diameter
OD = Outside Diameter
T = Thickness
NP= Nominal Pressure
SDR = Standard Dimensional Ratio
Relation between the Outside diameter and Thickness of the wall

Pressure terminology

PSI= Pound square inches
MPa= Mega Pascal
1 MPa= 10 Bar = 145 PSI = 1 N/mm² = 100 N/cm²
1 In² = 6.4516 cm²
1 cm² = 100 mm² = 0.155 In²
1 mm²= 0.01 cm² = 0.00155 In² = 0.00001076 Ft²
1 mm = 0.1 cm = 0.03937 In = 0.7854 mm² = 0.001217 In²

DRAG = Drag pressure

TEPA = Total Effective Piston Area

IFP MIN (60 PSI = 0.41 Mpa = 0.41 N/mm² = 41 N/cm
IFP MAX (90 PSI = 0.62 Mpa = 0.62 N/mm² = 62 N/cm

How to calculate Pressure Gauge according to the ASTM F 2620 American Standard?


(PG) = Pressure Gauge
PG = IFP*Ap + DRAG
TEPA
IFP = Interfacial Pressure
ASTM F2620 › IFP = 0.41 – 0.62 MPa / 60 – 90 PSI
DVS 2207 › IFP = 0.15 MPa / 21.75 PSI
Ap = (Pipe Area)
AP = (OD – T) * T * л
T = OD SDR = OD

Л = 3,14
TEPA = Total Effective Piston Area
DRAG = Drag pressure

HDPE PIPE FEATURES

THERMOPLASTIC PIPE VS TRADITIONAL PIPING SYSTEMS

  • Leak-Proof: HDPE pipe can be joined by thermal fusion to form a joint that is as strong as the pipe itself and is leak free. Thermal fusion eliminates potential leak points every 8-20 feet commonly found with Concrete, PVC and Ductile Iron pipe. Leak proof joints also eliminate infiltration and exfiltration problems experienced with other pipe joining methods. Since fused joints are self-restraining, costly thrust restraints or thrust blocks are not required.
  • Corrosion and chemical resistant: HDPE pipe will not rust, corrode, tuberculate or support biological growth and are resistant to chemical abrasion. It is the material of choice in harsh chemical environments. HDPE pipe has a smooth ID and maintains its flow capability over time – Hazen Williams C Factor remains 150, even after years of use.
  • Flexible and fatigue resistant: HDPE pipe can be bent to a radius 25 times the nominal pipe diameter. This can eliminate many fittings required for directional changes compared to piping systems made from other materials. In addition, the flexibility of HDPE pipe makes it well suited for dynamic soils and areas prone to earthquake. HDPE pipe for pressure applications can accept repetitive pressure surges that exceed the static pressure rating of the pipe. Thermoplastic pipes can withstand common damages, vibrations and pressure surges.
  • Lightweight and impact resistant: HDPE pipe is much easier to handle and install than heavier, rigid metallic or concrete pipe, allowing for cost advantages in the construction process. It is structurally better able to withstand an impact than other pipe materials, especially in cold weather installations when other pipes like PVC are prone to cracks and breaks.
  • Easy to install: Flexibility and leak free joints allow for unique and cost effective methods of installation of HDPE pipe that the rigid Concrete, PVC and Ductile Iron pipes can’t use. These alternate installation methods (Horizontal Directional Drilling, Pipe Bursting, Sliplining, Plow and Plant, Submerged or Floating Pipe) can save considerable time and money in most applications.
  • Cost-effective and permanent: HDPE pipe is cost effective and has long term cost advantages due to its physical properties, heated-fused pipelines create a leak-free systems, and reduced maintenance costs or repair needs, and conserve resources. Thermoplastics pipes, like Polyethylene (PE) are expected to last up to 100 years – saving replacement costs.
  • Seamless: Fused thermoplastic pipes create a monolithic pipeline with less mechanical transitions, meaning less opportunities for leaks.
