دستگاه کشنده همان طور که ار نام آن مشخص است.. وظیفه کشیدن لوله را به عهده دارد. چرا که لوله با توجه به فشاری که در داخل سیلندر هست تا حدی می تواند جلو بیاید و پس از آن متوقف می شود. این دستگاه باعث می شود لوله جلو تر آمده تا پس از دستگاه کشنده، اره بتواند لوله ها را به میزان دلخواه برش بزند.

The quality of the polyethylene pipe should be controlled along the production line according to production standards. Even with the best design and use of the finest raw materials, the lack of proper quality control during production can create adverse results from the final product. With a series of extruders (single tube), the pipe can be produced with high quality of PEX, ABS, PPR, PP. The rotating cutting machine can be controlled automatically by the computer . mentioned production lines are simple and reliable, and also are advanced in the world. The types of polyethylene pipe lines according to their sizes are as follows .

خط لوله آب از چندین دستگاه مختلف تشکیل شده است... این دستگاه ها شامل اکسترودر، وان وکیوم، وان خنک کننده، دستگاه کشنده، دستگاه اره میزی، خط زن لوله و لوله انداز می باشند. لوله انتقال آب که اکثر ساختمان ها و منازل دیده می شود از سه سایز  میلی متر، میلی متر و میلی متر است..فاده می شود.

It is used for pipes of water supply , sewage , agriculture , building industry and etc. this line include of single screw extruder , buckle , vacuum tank , cooling tank , haul-off , cutter , stacker . frequently speed control system of extruder , haul-off , vacuum motor , main motor of extruder  , all are well known and famous type and also have high efficiency . the production of PE pipe is apparently a simple and easy process but the process of producing a PE pipe deponds on the details that if a small error occurs in the production process , it can lead to a poor quality and unacceptable products. Equipments and spare parts for the production line of polyethylene is one of the most important factors in the quality of the finished product and these equipments must be used with the highest possible quality and ultimately in perfect harmony . production line of Pe should be modern and update , works according to the latest European standards and with the highest level of control , observes all production characteristics , control all components of an excellent product and in case of non-conformance, automatically solve the problem or stop the pipe production process . The precise control of weight along with the reduction of melt fluctuations of exhaust material from the mold in the cross-section and the length of the pipe is one of the most important parameters to be considered when choosing a polyethylene production line. The use of precise and advanced control systems makes this possible .

همان‌طور که گفته شد در پروسه تولید لوله UPVC در وینوپلاستیک از مواد مختلفی است..فاده می‌شود که هر کدام می‌توانند موجب بروز ویژگی و قابلیت‌های منحصربه‌فردی در لوله‌ها شوند. از جمله مهم‌ترین مواد مصرفی در تولید این لوله و کاربرد آنها می‌توان به موارد زیر اشاره کرد:
