In this second phase and in these not flooded surfaces, the aerobic bacteria Thiobacillus give rise to the production of sulphuric acid H2SO4according to this reaction: In this second phase and in these not flooded surfaces, the aerobic bacteria Thiobacillus give rise to the production of sulphuric acid H2SO4according to this reaction:.
PVC Pipes Made for fusing pipe from 63mm – mm 2″ – 6″ overhead, vertically and in the tightest locations.
The hydrogen sulphide reacts directly with many metals like iron and copper. The advantages of a dolly and functionality of a pipe stand create one of the most useful pipeline tools.
A quick and accurate socket fusion tool that allows one operator to align, heat, fuse and cool the pipe.
The process consists on two phases. Polyethylene PE pipes How electrofusion pipes and PE fittings are performed. Includes fusion machine, heater, facer, insulated heater stand and screw driver kit. Guided side Bend tester Includes testing unit and hydraulic hand-pump More information.
Leave a comment about this subject. Water Research Centre The pipes more affected by the corrosion because of the sulphides, are those who have cement in their composition, like the concrete, asbestos cement and foundry, whose internal protection is given by a thin sheet of cement mortar.
The hydrogen sulphide is also the gas which volcanoes release, it is yellow and with a strong smell like rotten eggs, this gas is toxic for human beings and has caused the dead of many operators of the maintenance equipment of sewerage networks.

Includes fusion machine, facer, heater, insulated heater stand and lifting assembly. That is why it must be avoided to climb down to the sewer pipes, what can be achieved with the modern systems of inspection by a robotized TV video camera and by cleaning the sewer pipes at the level of the floor.
The corrosion problem of the Sewerage Network
Save wear and tear on machinery, reduces strain on operators and makes the fusion process easier. Heaters and adapters are sold separately. What is important is to know that there are specifications to evaluate, classify and categorize the problems that we face in the sewerage networks. Characteristics of the trench for buried plastic pipes. Do you know Trenchless Technologies no-dig with plastic pipes?
Both the first document that it is in English like the second one which is in Dutch must be more updated at present. In the first one, the settled sludge by the action of anaerobic organisms saneaiento hydrogen sulphide SH2. Includes fusion machine, facer, heater, insulated heater stand and lifting assembly.
