The wall is made of metal sleeves; how can it be replaced with UPVC or fiberglass?
Thread Content
The pipes originally used on site were made of 316 stainless steel, and the medium handled was PAC; these pipes suffered severe corrosion. We would like to replace them with UPVC or fiberglass pipes. How can we connect them to the wall sleeves?
I don’t know what’s on the other side of the wall; it would be best to clarify that. For installation along the pool wall, a non-metallic pipe should be inserted from inside the pipe to the other side of the wall, after which leak prevention measures should be taken on that side. It’s just that the diameter needs to be reduced; I’m not sure if that will work. But this method is relatively simple. Otherwise, the metal pipe has to be completely removed, but this is very difficult. Because a water-stop ring should be installed on the metal pipe inside the wall. At the very least, half of the walls will need to be demolished, and it will also be very difficult to carry out waterproofing measures later on. Or open another one,,, Also, for reference, it is worth considering whether the distance between this valve and the wall affects its operation, and whether it would be better to be able to operate it by rotating it from the side.
Go to the market and find those who specialize in anti-corrosion pipes; they will inspect the site on their own and come up with a plan, completing the work in 2 days.
Adding a flange or thread transition will do.
PAC is short for polyaluminum chloride, a flocculant used in water treatment. It is a liquid that appears light yellow to yellow-brown in color; it is a water-soluble inorganic polymer that lies between aluminum chloride and aluminum hydroxide, and is thus referred to as a water treatment flocculant. In the process of water treatment and purification, polyaluminum chloride helps accelerate flocculation, enabling the impurities in water to form flocs that settle, thus achieving a relatively thorough separation of water from these impurities. Compared to traditional inorganic coagulants made up of low-molecular-weight crystalline salts, polyaluminum chloride is composed of inorganic polymers with diverse structures. It features rapid flocculation and sedimentation speeds, as well as significant water purification effects; it can effectively remove heavy metals such as arsenic and mercury from water. Additionally, its pH range
If it is this type of medium, polyaniline can be used for anti-corrosion inside the pipeline
