Butt ( tig ) welding pex-al-pex pipe produce line of Chase Machinery Co., Ltd

Model Tpexal-32, Tpexal-63, Tpexal-110, Tpexal-200 .
Tig welding pipe and machines are as same as Henco , Hewing , Swisscab , APswiss .

For bigger sizes of multilayer pipes (bigger than 40mm) , we have found the best solutions for you , you can use low cost (stainless) steel sheet , but not the expansive Aluminum sheet . Our line is good for multilayer pipe making up to 200mm .

*Advantages
Began from 1994 year , we studied and researched by ourselves the production technology of butt-welding PEX-AL-PEX composite pipes , and in 1998 we successfully made a top-quality , fully computer-controlling Tig butt-welding PEX-AL-PEX composite pipe production line . It's a combination of welding and mechanics technics , a combination of many theories and practices .

It can weld Alu-sheet of thickness from 0.2-2mm , has a high production speed :15M/min , easy to control and handle .

2).advantages

a.       advanced technology
Hi - precision inverse transformation welding power sources are applied , electrical current and   data are indicated digitally , IC tension control , on-line eddy current check on defect welding , hi-frequency heating and fully computer control , all these make it advanced in technology at home;

b.      professional computer-controlling is its hi-class mark
It’s a combination of lots of lab tests and actual practicing experiences . PII industrial computer (Windows NT) monitoring and program control , free of interference manual and auto-convertion ,
It’s really completely synchronous , to make a easier , more practiced and durable operation .
Multi-missions vague controlling technology and web/Lan technology are applied , making a easy , reliable and friendly control for the whole line .

c.       fine workmanship , hi-quality
All key parts and components are made of the best materials at home, those purchased ones are hi-quality imported electronic devices ( frequency conversioner , coder etc) . précised CAM technology, advanced processing and measuring ways are applied in manufacturing , making dies and tool carriers get very high precissions.ISO9000 system is applied , after assembled , the whole machines perform very well , durable to run,1^st successful running rate is up to 98% .

Our precision CAM technology make sure that we can have a continuous précised alu-tube forming , as it can avoid alu sheets’ going off course and going winkling , thus a very round and good alu tube can be made stably.

Typical and patented Integrated alu-tube tightening technology (national patent) can make a durable adhesion on Polymer and alu sheet.

Solid hi-frequency heating is of hi-efficient , water and energy saving , polutionless , there’s no any thermal interia , It’s easy to control heating temperature , which can be adjusted and controlled by computer precisely and continuously . it’s the best heating way for pex-al-pex pipe making , especially for adhesive bonding to polymers and alu-sheet.

In order to get a solid welding on the very thin alu sheet, hi-precision inverse transformation welding power sources are applied , which is of light in weight , hi-efficient , stable welding current , good welding seam forming.

d.      hi-quality welding
smooth welding seals , welding parts are stronger than their mother materials . This technology has been used to prove to be the best and potential welding way , making the best welding quality , by Germany , Sweden and other developed countries .

e.       wide range of welding
we studied and made a hi-quality welder for PEX-AL-PEX pipe specially , It's major electronic devices are all of foreign famous brand names . Welding thickness:0.25-1.5mm , up to 3mm is also not difficult , can weld all big size pipes , and have great advantages against ultrasonic welding when welding big size pipes .

f.        hi-roundness pipes with even walls made by this machine
butt welded Alu-tube after being drawn has a roundness below 0.15,much better than overlap welding tube , thus the whole composite pipe is very round , with even wall thickness and strength , without any weak parts .

g.       hi-productivity      15M/min

h.       easy to handle
practiced single layer plastic pipe extruding way is applied to composite pipe’s inner PE pipe making, and inner adhesive extruding , easy to operate , monitor and adjust.

PII Computer control systems (Windows NT) and touch control panel are applied , which have the following advantages:

1.      it’s composed of 1 main control and 4 sub-controls , reasonable layout ;

2.      all controlling subjects on the line have special controllers , located at site on line , very easy to handle;

3.      site-bus and distribution cablings of international standard Web technology are applied , making a reliable performance and anti-interference properties , especially anti hi-frequency interference.

4.      data from main controller can be reliably distributed to all site sub-controllers , at the same time , all working data from sub-controllers can be sent to main controller;

5.      computer system can then automatically learn all data , and find the best running curve for the whole line;

6.      computer controlling or site manual controlling can be easily converted , very convenient for installing and adjusting ;

7.      its smart controlling structures giving a easy controlling reconstructing and extending ;

8.      when a controller failed to work , there’s no any interference to others , the main controller and other sub-controllers can work normally .

In order to get easy , reliable and practiced handle on the compricated whole line , we use the following technologies :

1.many kind of advanced controlling technologies;

2.      IC PID close-circuit technology on temperature control;

3.      close-circuit technology on extruding speed;

4.      accompanying technology of welding machine’s current and speed;

5.      technology of 3 haul-offs working synchronously;

6.      auto speed converting control technology , no waste giving out when speed converting ;

7.      power of hi-frequency hearer auto converting to running speed of the line .

   i.         Pipes can be made

its inner layer PEX pipe, welding and outside Pex pipe can completely independently work , thus it can make , besides composite pipes , PEX pipe , PPR pipe and PB pipes…

j. hi-quality , low price

its price is only 1/10 of European machines with the same parts and components.

k. good after-sale service

we have welding , controlling , mechanics , plastics and other professional engineers , can supply with you complete and in-time service.
