I can't quite found out what these specifications mean:
(01) 101,372 m PVC water pipes JECE (63 mm x 3.6 mm)/10 including rubber ring
(07) 5,656 m PVC sewage pipes JSCE 50 mm
(11) 9,702 m PVC sewage pipes JECE (250 mm x 4.9 mm) including rubber ring
The numbers mean, for example:
"nine thousand seven hundred and two meters" of pvc pipes suitable for sewage water, diameter 250 mm and thickness 4.9 mm
PVC = Polyvinyl chloride not laminated
JE = ELASTIC JOINT
JS = SOCKET WELD JOINT
C = PLUG (or head)
E = SPIGOT (or cord)
(D x e) S20 and S25
D = Outside nominal diameter
e = Wall thickness
S = Series
My doubt comes to what the plug, the spigot, the elastic joint and the other stuff actually are.
Have you got a manufacturer's manual that explains these things?
An advice on a good manufacturer of PVC pipes would come handy too.
I have translated the specs from Spanish, so there might be errors as I am not familiar with piping.
