Q:Natural gas aluminum pipes, what fittings are best used?
Special pipe fittings for copper plastic aluminium tube.The aluminum plastic pipe is a composite pipe which is welded longitudinally by an intermediate aluminum pipe and is lined with polyethylene plastic inside and outside, and is bonded with hot melt adhesive between the layer and the layer. According to the use of classification, there are ordinary drinking water pipes, high temperature pipes, gas pipes. Gas aluminum composite pipe has yellow Q mark, mainly used to transport natural gas, liquefied petroleum gas and gas pipeline system. Because the middle layer of aluminum plastic pipe is made of aluminum, the permeation of gas on plastic can be avoided, so the utility model is more suitable for gas pipelines.
Q:PE plastic pipe surface is concave, how could it happen?
Measures should be taken to protect or adjust the connection process under cold weather (--5 degrees below) and strong wind conditions.
Q:PVC what's the direct head of the outside pipe?
Hello, PVC, the outside of the pipe is directly attached to the external tooth.Wire and teeth refers to the pipe metal parts of the thread, the outer wire is the outer thread of the pipe, is metal pipe and non-metallic (mainly refers to PP-R, PVC and other plastic pipes) directly connected pipe fittings.PVC water supply pipe and wire directly, as with the pipe connection.
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?
The draft tube is preheated and the vacuum setting pump is opened at the same time. The vacuum pump is used to adjust the discharge volume of the sizing sleeve.
Q:The difference between PP-R aluminum pipe and PP-R pure plastic pipe
From the connection way, aluminum plastic pipe is a physical connection, simple and convenient, unless the operation is improper, its safety and reliability is very high. PE pipes and PP-R pipes with hot melt or welding connection, complex process, easy to produce stacking defects, lead to stress concentration, influencing the long-term performance of pipeline; in addition, the local high temperature fuse facilitates pipeline material degradation, accelerated aging pipeline
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:Plastic pipe fittings and cast iron pipe fittings are not the same technical field
The most widely used plastic pipe is plastic pipe. There are many kinds of plastic pipes, which are divided into two categories: thermoplastic pipes and thermosetting plastic pipes. It belongs to thermoplastic, including PVC pipe, polyethylene pipe, polypropylene pipe, POM pipe, etc. it belongs to thermosetting phenolic plastic pipe. The main advantages of plastic pipes are good corrosion resistance, light quality, convenient molding and easy processing. The disadvantages are low strength and poor heat resistance.
Q:Can the PPR pipe be injected with the same pipe as the PVC pipes?
Tolerable。 As long as it is thermoplastic, all injection molding machines can be produced.
Q:How about plastic pipe fittings?
Heat resistance (standard referred to as oven test). The good pipe is baked at the 150 - hour oven by the wall thickness
