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
