This made identifying the problem difficult as Poly-B pipes may look fine on the outside but inside they are slowly deteriorating waiting to break open.

And lastly, it turned out that Poly-B pipes had trouble handling hot water and chemicals such as chlorine and began to break down quite quickly. Water pressure was also a problem as areas with high water pressure could cause a joint to rupture.

At first, it seemed to be a problem with the fittings.Many of the fittings used were made of plastic which cracked and leaked over time.In some instances, fittings were installed too tightly and would slowly start to crack leading to leakages. However around the mid-80’s, many Poly-B plumbing systems began to leak. This type of pipe was greatly used in the late 1970’s till late 1990’s due to it being cheaper than copper and easy manoeuvrability. Poly-Butylene pipes, also known as Poly-B, is a gray plastic pipe used to supply domestic water and hydronic heating. According to different connection forms, welding can be divided into butt welding and socket welding.Poly-Butylene Pipes ​ Poly-Butylene Pipes After the stainless steel pipe is welded, the weld surface shall be protected, such as applying acid pickling passivation paste. For the stainless steel pipe with smaller diameter, it can also be directly sealed with argon arc welding.

Threaded connection is a widely used removable fixed connection, which is easy to install, stable and reliable in quality.įlange connection is a kind of connection mode that two pipes or pipe fittings are respectively fixed on a flange plate, then a flange pad is added between the two flange plates, and finally the two flange plates are tightened with bolts to make them closely combined.Īrgon arc welding is generally used to seal the bottom of stainless steel pipe, manual arc welding is used to cover the surface, and argon is filled into the pipe for protection, so that the inner weld of the pipe does not produce oxidation.

This connection is mainly used for the connection of steel pipe, copper pipe and high-pressure pipe. The use of extrusion connection method to realize thin-walled pipes and pipe fittings, save materials, the pipes are not removable, and the quality of pipes is required to be high.Īlso known as screw connection, it is through the internal and external thread to connect the pipeline and pipeline, pipeline and valve. After inserting, use special tools to squeeze the connection, clamp the pipe fitting on the pipe, and achieve the connection through the sealing ring water stop Effect. When inserting, the central axis of the spigot shall be aligned with the central axis of the bellmouth. Insert the spigot into the bellmouth (compression type connection, ring compression type connection, double compression type / double extrusion type connection is to insert the pipe into the pipe fitting, plug in compression type connection is to insert the pipe fitting into the pipe fitting). The common stainless steel pipe connection methods mainly include extrusion connection, the Thread Type Connection, flange connection, the Welding Type Connection, etc.
