Q:Who knows the size of the PVC pipe and what is the maximum and minimum size?
The physical properties such as molecular weight, crystallinity and softening point of PVC change with the polymerization conditions (temperature). PVC resin is used as base material and mixed with various additives such as stabilizer, plasticizer, filler, colorant and modifier. It is plasticized, molded and processed into PVC resin plastic. PVC material has light, heat insulation, heat preservation, moisture-proof, flame retardant, simple construction and so on. Specifications, colors, patterns, and very rich decoration, is widely used in production and life. For example, PVC water pipes, PVC plastic doors and windows, and plastic toys containing PVC, wires and cables.
Q:Spiral drain pipe fittings are not special pipe fittings
1 vertical compression to the outer diameter of 40%, immediate unloading, the specimen does not rupture, not stratified.2, the temperature at 0 degrees, high 1M conditions, with a weight of 1Kg heavy hammer, impact 10 times, should be more than nine times without cracking.3. The inner wall is even and smooth. The water permeable holes are evenly distributed below 1/2 in the height of the trough. The number of holes at the height of the trough is not more than 10% of the total number of 1/2.4, water area is larger than 45cm2/M
Q:What are the characteristics, properties and uses of PVC plastics?
PVC can be divided into soft PVC and hard PVC. Among them, hard PVC accounted for about 2/3 of the market, soft PVC accounted for 1/3. Soft PVC is generally used for flooring, ceiling and leather surface, but because the soft PVC contains softening agent (this is the difference between soft and hard PVC PVC), crisp, not easy to save, so the range of use is limited. The hard PVC does not contain softener, therefore, the utility model has the advantages of good flexibility, easy molding, uneasy brittleness, no poison, no pollution and long storage time, so the utility model has great development and application value. The essence of PVC is a kind of vacuum blister film. It is used in the surface packing of various panels, so it is also called decorative film and adhesive film. It is applied to many fields such as building materials, packaging, medicine and so on. Among them, the building materials industry accounted for the largest proportion, 60%, followed by the packaging industry, as well as other small range of applications.
Q:What are the manufacturing processes of plastic pipe fittings?
After the host heat preservation time, opens the feeding baffle plate, opens the main engine to adjust for 10 turns13. when the time of holding the machine is over, turn on the feed machine baffle and turn on the coextrusion machine20HZ or so.
Q:PPR pipe fittings, copper pieces, that are embedded parts and plastic parts are not good, appear pressure leakage situation
The water supply pipe is connected with the metal pipe polypropylene, polypropylene pipe should be used with metal fittings as a transition, the pipe and the plastic pipe by hot melt connection, connected with the metal fittings or sanitary hardware fittings with wire.
Q:What kinds of plastic pipe fittings are there? What are the various uses? And how to distinguish quality?
Plastic pipes are generally divided into water supply, drainage, power communication pipes, etc. according to the material, they are divided into PVC-U, PVC-C, PE, PPR, HDPE, PP, PB and so on.
Q:Regarding the connection of plastic pipes and inspection wells, is the flexible connection or rigid connection?
The connection between the pipeline and the inspection well shall be constructed according to the design drawing. When the socket pipe is connected with the well wall of the inspection well, the socket pipe fittings shall be supplied by the manufacturer;
Q:What is the difference between plastic pipe fittings and hot melt plastic water supply pipe fittings?
As the name suggests is lining plastic pipe in the pipe wall lining a layer of plastic, for the purpose of internal corrosion of steel pipe, but as a senior sales staff, the deaf ears furnishings still can be divided clearly, pipe lined with plastic for wire, tube wall has plastic layer, but the pipe with a connection, the inner wall of the pipe the plastic layer and the middle layer plastic pipe wall cracks can not reach the requirement of water resistance, a long time will cause the plastic layer and the steel layer from the water can not circulate time wall middle long will breed bacteria instead of water pollution.
Q:What are the common connecting methods for plastic PP pipes?
The common ways of connecting plastic pipes are adhesive connection, rubber ring connection, welding connection, and mechanical (clamp type pipe fitting) connection. For polypropylene (PP) pipes, there are three common ways of connection, namely, hot wire welding, butt welding and loop flange connection.
Q:How can the PPR pipe be connected with the metal tubes?
This is a water storage type electric water heater installation and use of PP-R material, and is connected with the water heater outlet and below the triangle valve components is a special joint installed in the water heater, the components are used to transition metal tube connected with the plastic pipe, the connecting way is to facilitate future maintenance.
