Technology description

When  performing  sleeve  welding  with 

the help of heating sockets on the heating 

element,  pipe  joint  and  profiled  part  are 

lapped.  Pipe  end  and  sleeve  of  the  pro-

filed part are heated with the help of heat-

ing  spigots  and  sockets,  installed  on  the 

heating  element,  and  then  joined.  There 

are  two  methods  of  sleeve  welding  with 

different sizes of the spigot and sockets. 

Method  A  does  not  include  mechanical 

tooling of pipes, method B includes me-

chanical tooling – centreless grinding.

Heating  spigots  and  sockets  ZENIT  are 

intended for method A welding only.

 

Sleeve  welding  with  the  help  of  heating 

sockets  can  be  performed  on  pipes  with 

diameter up to 63 mm.

When working with pipes of bigger diam-

eter it is recommended to use an appropri-

ate welding machine.

3.2. 

Prior to welding

Follow recommendations of the pipe man-

ufacturer and profiled part manufacturer!

End  of  the  pipe  must  be  cut  square  and 

evenly.  These  parameters  are  achieved 

by using pipe shears. Besides, end of the 

pipe must be beveled for easy joint. Right 

before welding pipe end and internal sur-

face of the sleeve of the profiled part and 

heating  spigot  and  socket,  if  necessary, 

are  cleaned  with  a  piece  of  paper,  leav-

ing no paper dust or a napkin leaving no 

filaments,  moistened  with  gasoline  or 

commercial  alcohol.  Make  sure  plastic 

remainders  don’t  stick  to  the  surface  of 

the  heating  socket.  When  cleaning  heat-

ing sockets make sure not to damage spe-

cial teflon coating. Do not touch surfaces 

treated in this way before welding.

Welding technology

3.3.1.  Heating  of  pipes  and  profiled 

parts

To heat the pipe and profiled part quickly 

insert  them  on  heating  spigots,  fixed  on 

the heating element of the machine, to the 

end position or to the marking, and keep 

for time required (see welding table).

It is recommended to follow instructions 

of the pipe manufacturer.

When heating, the heat gets inside the sur-

faces to be welded and Во время разогрева 

тепло  проникает  в  подлежащие 

спаиванию  поверхности  соединений, 

доводя их до нужной температуры.

3.3.2.  Welding and fixing

After  heating  remove  the  pipe  and  pro-

filed part from the spigots of the heating 

element and push them inside one another 

without turning. Fix (hold) them for a pe-

riod of time, recommended by the plastic 

pipe  manufacturer  (see  welding  table). 

Time  between  removing  from  the  heat-

ing element and welding must not exceed 

time, recommended by the pipe manufac-

turer (see welding table). Otherwise weld-

ing surfaces will not be heated enough for 

quality welding. 

3.3.3.  Cooling

Load on joints must be applied only after 

estimated  cooling  time  (indicated  by  the 

plastic  pipe  manufacturer),  (see  welding 

table).

4. maintenance

 

ATTENTION!  Before  maintenance  and 

repair disconnect the tool from the power 

source  and  let  it  cool!  These  operations 

must be performed by qualified specialists 

only.

Before every welding clean the teflon coat-

ing of the heating element spigots with a
