PVC to ductile iron adapter according to the standard atlas can be divided into: national standard and non-standard. The national standard waterproof casing refers to the selection and production of the 02S404 or 02S312 standard atlas according to the Ministry of Construction. It has strict requirements on flange thickness, wing ring thickness, pipe diameter and thickness. Non-standards are in the case of the shape and the approximate structure conform to the standard atlas. When selecting materials, the thickness of the flange, the thickness of the wing ring, the diameter of the pipe and the thickness are considered to be relaxed. Strictly speaking, these are unqualified products. Of course, certain The relaxation criteria within the degree will not affect the use, but the excessive relaxation criteria will affect the performance. PVC to ductile iron adapter according to the atlas, it can be divided into: S312 type flexible waterproof casing and 02S404 type flexible waterproof casing. Both have different dimensions and structural forms.

Description
The ductile iron dismantling joint is also called a telescopic joint, an expansion joint, and a compensator. The telescopic device can be axially extended and retracted within a certain range, and can also overcome the deviation caused by the different axial directions of the pipe in a certain angle, which can greatly facilitate the installation and disassembly of the valve pipe, and can be freely allowed in the pipe to allow the expansion and contraction amount. Stretching, once Ductile Iron Dismantling Joint exceeds its maximum amount of expansion, it will limit the position and ensure the safe operation of the pipeline.
The Ductile Iron Dismantling Joint consists of the main body, the sealing ring, the gland, the telescopic short pipe and other main parts. Ductile Iron Dismantling Joint is a new product that connects pumps, valves and other equipment with pipelines. Ductile Iron Dismantling Joint connects them into a whole through full bolts, and has a certain displacement. In this way, it can be adjusted according to the installation size on site during installation and maintenance, and the axial thrust can be transferred back to the whole pipeline during work. This not only improves work efficiency, but also plays a certain protective role for pumps, valves and other equipment.
