Cast iron pipes
WHAT ARE CAST IRON PIPES LIKE?
Until the 1970s, most sewer pipes were made of cast iron. After this, the plastic pipes were taken into use as well.
Cast iron pipes tend to vary only in weight. The options that were available were heavy, medium and light cast iron pipes. Cast iron pipes continue to be used in some sites because of their good sound absorption qualities. Due to their good resistance to mechanical strain, they are used in places where they remain visible, such as in basements of blocks of flats.
Cracking is the biggest problem associated with cast iron pipes. This is caused by the deposits accumulated on the inside of the pipes during thermal expansion. Cast iron pipes should, in fact, be cleaned every 10 years and refurbished every 30-60 years.
CAN ANYONE FIX OR CLEAN CAST IRON PIPES?
Particularly when it comes to the restoration of old buildings, it can be dangerous to do plumbing work on your own. Even though the pipes do not yet leak, old sewer pipes may be in such poor condition that the handling process can cause leakage.
It can also be difficult to ascertain the health of sewer pipes ahead of time. The effect of corrosion on cast iron pipes varies significantly. On average, these pipes corrode 1mm in 10 years. Consequently, the assessment of the possible need for pipe renovation as well as the actual pipe refurbishment should always be carried out by a professional.
A thorough sewer renovation executed by a professional significantly increases the value of old properties. Call on NewLiner when you need reliable, quick and convenient pipe renovation!
