| In
same acreage,girth of rectangular is about 20% more then that of oval,e.g.,rectangular
needs more materials ang so the cost is higher. |
| The
major adventage, of the oval tuber pipe is£º |
| 1¡¢ The
full-automatic mechanical chemical plant produces, the products have
no dust clean |
| 2¡¢ Wet
Zhou Xiao of section, the leaking out rate of the tuber pipe is extremely
low |
| 3¡¢ The
lock is sewn tightly, lock the chink levelly and smoothly and not
let out when in charge of, lock and sew have function which strengthens
the muscle |
| 4¡¢ The
structure is highly in intensity, rigidity is good, prevent two noises
from producting |
| 5¡¢ Have
lopnger continuous length (It is in change of longs to be 4-8M generally),size
kind tuber pipe have it is simple and convenient to install. |
| 6¡¢ Occupy
space to be highly little, adapt to layers of high insufficient building
ventiulation tuber pipe of space |
