drained out. Therefore, it is recommended that water from the cooler is directed to the water tank in
Fig.4-7 as a water source to the extruder.
Note: In pipeline installation, water outlet pipe of the oil cooler should miss the drainage pipeof
steam condensate must, or else it will cause steam to flee into the cooler.
(3)Steam pipeline of pipeline system
1. Steam inlet joint 2.Steam to conditioner
Relevant Requirements for each joint of steam pipes on pipeline system
 Steam inlet joint: steam inlet flange of steam manifold is DN100 and the pressure to
steam to this inlet shall be higher than and equal to 0.6MPa of saturated steam.
 Steam to the conditioner: This flange shall be connected with the joint of Part #1
and Part#4 in Fig.4-11; the specification of pipe fitting applies DN80.
 Steam to the extruder barrel: This flange shall be connected with the joint of Part #1
in Fig.4-10; the specification of pipe fitting applies DN40;
 Steam to jacket of the extruder barrel: This flange shall be connected with the joint of Part #3 in
Fig.4-10; the specification of pipe fitting applies DN20;
 The piping of all the above steam pipelines to use seamless steel pipe.
(4) Pipeline of principal machine
See Fig.4-10 Pipeline of principal machine is installed on the support rack. Relevant requirements to
pipeline of principal machine are as following:
 Steam inlet to the extruder barrel: This flange shall be connected to the joint with
part# 3 in Fig.4-9; the specification: DN40;
 Condensate drainage: This joint is used for condensate water drainage, mainly to
drain the condensate in the primary pipeline for startup. Before each startup, drain it once
with a drainage amount of 1~2kg.

Steam inlet of jacket: This inlet shall be connected to the joint with Part #4 in
