RIYANG fusion machines are capable of fusing a variety of different types and sizes of thermoplastic pipes.
Corrosion is one of the most costly problems associated with metal piping systems. It occurs both inside and outside the pipe and affects hydraulic efficiency. Many cities treat their water to help slow rust and pitting that is inevitable with metal pipes. Others choose costly cathodic protection, plastic coating, or sleeving to try and extend the service life of the pipe.
Unlike traditional metal infrastructure products, HDPE pipe does not rust, rot or corrode. It is resistant to biological growth. This means an extended service life and long term cost savings.
HDPE pipe is flexible and ductile, not rigid. It has outstanding resistance to fatigue. Unlike other plastic pipes, it is designed and pressure rated to handle the kind of occasional and recurring surge events that are common in water distribution systems. HDPE pipe is a safe and durable product ideal for your piping infrastructure. The service life of HDPE is estimated to be between 50 to 100 years, depending on application, design and installation.
Heat fusion welded jointing methods create a completely homogeneous joint which is as strong as, or stronger than the pipe itself. This eliminates jointing chemicals (like in PVC pipe) or rubber seals which can fail over time, also solving root intrusion problems, and provides pipeline integrity where installed in unstable ground.
Because high-density polyethylene pipe is smoother than steel, cast iron, ductile iron, or concrete, a smaller diameter HDPE pipe can produce an equivalent volumetric flow rate at the same pressure. It has less drag and a lower tendency for turbulence at high flow rates. HDPE’s superior chemical resistance and non-stick surface characteristics nearly eliminate scaling and pitting, preserving the excellent hydraulic characteristics throughout the pipe system’s service life.
High-density polyethylene pipe installations are cost effective and have long term cost advantages due to its physical properties, leak free joints and vastly reduced maintenance costs. This relates to savings in replacement costs for generations to come. The properties of PE also allow unique installation methods, such as Horizontal Directional Drilling, Pipe Bursting, Slip-lining, Plough and Plant, Submerged or Floating Pipe, etc.
Traditional piping systems are installed by open cut (digging a ditch), resulting in traffic and environmental disruption. HDPE can be installed using this traditional open-cut method or by utilizing eco-friendly trenchless technology. For trenchless installation, a horizontal directional machine bores a continuous hole beneath the ground. When the drilling head reaches the end of the bore, the pipe is attached and pulled back through the hole.
It is much easier to handle and install lightweight HDPE pipe vs. the heavier, rigid PVC or metallic pipe segments, allowing for cost advantages in the construction process.

To properly fuse the thermoplastic pipes and ensure the weld quality, the operator is always obliged to find the right fusion pressure and time under the welding standard which requested by the project.
You could consult with our sales to ask for the welding table for Riyang butt fusion machine (Riyang fusion pressure calculator is on the way), or you could use other fusion pressure calculator APP to work out the pressure and time.This page will indicate how to calculate the fusion pressure and time manually, we will use the standard ISO21307:2017 as an example.Standard: ISO21307:2017 Single Low-pressure
Machine: Riyang Basic Butt Fusion Machine V315
Pipe: OD315, SDR17

Check out the formula of the gauge pressure calculation
GPis the gauge pressure (bar);
IPis the interfacial pressure (MPa);
ACis the total effective piston area, given by the manufacturer of butt fusion machine (mm2)
ASis the interfacial surface area (mm2)
DPis the drag pressure
Note: The interfacial pressure is the amount of force per unit of pipe area required to butt fuse the pipe or fitting ends.
Note: The interfacial pressure is the amount of force per unit of pipe area required to butt fuse the pipe or fitting ends.
Refer to below tables for phases , parameters and values for single low-pressure fusion jointing procedure
1.(en + 3) This is the cooling time for the butt joint when still in the machine and under pressure. Cooling time may be shortened and should be lengthened depending on ambient temperature (approximately 1% per 1℃)
2.(d) A cooling time out of the machine and before rough handling maybe recommended.
Now using all information and formula above we will calculate all values by maximum
en= dn/ SDR = 315mm / 17 = 18.52 mm
P1= P3 0.19 x {π x (dn-en) x en}÷2000 x 10} + 5 (for example) = 21 bar
P2DP = 5 bar
t1= bead-up size 0.5 + 0.1 x 18.52mm = 2.3 mm
t2(13.5 ± 1.5) x 18.52 = 278 s
t310 s
t43 + 0.03 x 315 = 12.5 s
t50.015 x 18.522- 0.47 x 18.52 + 20 = 16 min
