Hi, Muzammal

PVC can be joined to PVC by hot air welding with plastic welding rods and an electric heat gun, Muzammal. It can also be joined, in the case of pipes for example, by gluing (solvent welding). The electric heat guns and welding rod are widely available and the solvent system is on many hardware store shelves, but if not available in Pakistan you can read the MSDS for the commercial products and it will list most of the ingredients. But when you interject "medical grade", I unfortunately have no idea what requirements that adds or what standards need to be met. Sorry!

Hi Muzammal !

You should investigate this site some more!

Go to the first page of finishing.com and zoom down to the LIBRARY. Then vector down around 8 headings to PLANT AND PROCESS ENGINEERING .... lo and behold, at the bottom is an article called HAVING A LEAK ON THE JOB ... and this is all about joining PVC using cement or via threading.

I was also bemused by your wording of Medical Grade ... and can only assume you mean a type l, grade 1 uPVC and not a high impact PVC.

But don't try any welding UNTIL you are experienced ! Your strengths will be very poor. As for me, ah, I was a lousy welder and hit maybe 26% of tensile ...but our trained fabricators all hit over 85% yet one unionized Company demanded that they, too, should be able to compete as they had 'welders'.... but the very best test they showed was a paltry 30% of tensile.

Mr. Cheema how are you?
I read what you are seeking, but am not sure what kind of PVC you are using. Is it clear medical grade? Normally that is flex or plasticized PVC.
One of the reader has advised you about the uPVC which is un-plasticized PVC (also called as "rigid PVC".

In either case the welding of the two would not be very difficult. You can use PVC cement, PVC solution, Ultrasonic welding etc. It all depends upon what is the final application.

Thanks and Good luck!
