Cast iron pipes .Prices and features of the installation .

Technical properties of iron drain pipes

The title is no exaggeration.Cast iron pipes is of good quality indeed have a lifespan of up to 100 years under normal operating conditions.Most importantly, unlike their fellow fans plastic pipes made of cast iron with alloying additives have long proved their high operating status.Due to what?Let's investigate.

in the global markets of water supply equipment, always pragmatic rules.The cheaper and more reliable pipeline system, the easier it is to sell to the end user and to insure themselves against claims and lawsuits.Cast iron pipes for sewerage very rarely fails of its producers, while maintaining virtually unchanged for decades manufacturing technology.What are they good?

• mechanical properties .The ideal can not be called.Products even alloyed with magnesium, chromium, titanium, or other chemical additives iron remain weak resilience.On the other hand, the pipe for sewerage operate in ramjet pressureless systems where their internal strength properties are much more important, and in our opinion the best.
• corrosion resistance.This component of gray cast iron is comparable to the modern plastics.With high-quality processing of internal surfaces in molding education clear of corrosion on internal surfaces of the pipe does not occur, and the "collapse" of the local occurs naturally.
• Technological quality.It manifests as a stage production of pig-iron sewer pipes, as well as their installation and operation.The low coefficient of thermal expansion, high (due to the thickness of the walls) the effect of sound insulation, environmental cleanliness (a natural material without impurity of synthetics).

If you add a high temperature stability, absolute indifference to the fires and practically zero wear process of the internal surfaces of pipes, their first in this market segment can be considered quite natural.

installation of sewage systems cast iron pipes

Before distributing the sewer system it makes sense to get acquainted with GOST 6942-98, which of these lines says almost everything.Some important points:

• cast iron pipes for domestic sewage and fittings for them are made with a diameter of 50, 100, 150 mm;
• bitumen coating internal and external surfaces must retain the softening temperature of 60 degrees;
• maximum temperature control - 400 degrees.
• connecting elements (padding, couplings, tees straight and angular, crosses, caps, etc.) Are selected from the assortment of products.

Cast iron pipes 50 provide a convenient layout within the home network, and access to a diameter of 150 provides a guaranteed discharge of sewage into the overall system fans.When you select should be noted that in the passport products may be present three values:

• internal nominal installation diameter (Dn or Dn);
• outer diameter: figure is an important, but often derived;
• thickness of the pipe wall that defines the cross-section of a conditional pass.

mounting system made by simply inserting the straight portion of one part to another part of the fitting and sealing of the gap tarred hemp tow.Flare naturally located in the opposite direction to the drain.The branching circuit arranged in the same order.

cost of cast iron pipes for sewerage.The issue price.

us, ordinary citizens, often concerned about two issues: how much this thing will cost and how much it is difficult.For the most curious report that the tube length is 2 m and weighs about:

diameter	wall thickness	Weight kg	Price, rub.
50	4,0	11,0	800
100	4,5	25,1	1260
150	5,0	40,3	2280

As you can see, set in suburban homes are sewer pipes profitable even economically, especially given their infinite lifetime.Shipping costs and installation will be repaid within a year.
