Why should we choose PPH valve, pipe fitting or pipe
PPH valve is a kind of valve made of polypropylene (PP) material, which has the characteristics of lightweight, easy maintenance, good interchangeability and so on, so there are many uses in production and life. The following are some common uses:
Chemical industry:
In the chemical industry, PPH valves are widely used in the pipeline control of various corrosive media, such as acid, alkali, salt and so on. Due to its excellent corrosion resistance and strong anti-aging properties, PPH valves can work stably for a long time, which effectively ensures the safety and stability of chemical production.
Water treatment industry:
PPH valves are also widely used in the field of water purification and sewage treatment. Due to its excellent hygienic performance, does not contain toxic substances, PPH valves in the water treatment process will not produce secondary pollution of water quality, so in the water treatment industry is highly favoured.
Food industry:
In the food industry, PPH valves are widely used in food processing and packaging processes due to their non-toxic, odourless and corrosion-resistant characteristics. For example, in beverage production, PPH valves can be used to control the flow and direction of flow of beverages; in food packaging, PPH valves can be used to control vacuum systems and pneumatic systems.
Pharmaceutical industry:
In the pharmaceutical industry, PPH valves are widely used in the production, storage and transport of pharmaceuticals due to their high cleanliness and good corrosion resistance. For example, PPH valves can be used to control the flow direction and flow rate of medicine during the filling process; in the storage of medicine, PPH valves can be used to control the humidity and temperature of the warehouse.
On the market, there are UPVC,CPVC,PPH,PVDF,FRPP valve, and pipe system. The following reason that Why should we choose PPH valve, pipe fitting or pipe?
What the Characteristic of PPH material ?
Polypropylene Homopolymer (PP-H) is another type of PP. It has better temperature & creep resistance than PPR, and with low temperature impact strength.
Presently PPH pipes & fittings are most reliable in plumbing and water supply plants, due to their chemical features and fusion welding, which ensures the plumbing to have a perfect seal tight system. Approved by the Health Organization with characteristics such as Eco-friendly and high temperature resistance, PPH/PPR pipes & fittings have been taken as one of the best solution for piping systems.
Max temperature of PPH pipes is 110℃, and they are usually used below 90℃. They are applied for cooling water transfer, corrosive material transfer, fume ducts, electrolyze systems, and other piping systems with acid liquids.
What is PPH Physical Properties?
What is PPH products connect method?
PPH pipe system is bonded by hot melt, which can be divided into hot melt socket welding and hot melt butt welding. The specific steps of hot melt socket welding are as follows:
Guide the pipes into heater straight to the marked assembly depth. In the meanwhile, push the fitting onto the heater and reach the marked depth.
Guide the pipes into heater straight to the marked assembly depth. In the meanwhile, push the fitting onto the heater and reach the marked depth.
Heating time must be complied with the values in the under table(next page). After heating time, remove pipe and fitting from the heater immediately and assemble them to the marked depth straight so that there is even bulge is the assembly place. Within the working time, tiny adjustment can be made but rotation must be prohibited. Keeping pipe and fitting from being wrenched, bent, and stretched.
If the environment temperature is lower than 5℃, extend heating time by 50%
When aligning, put the welding sides on the hot iron until the whole side full touch the hot iron completely, side to side, and it can observing the flanging formation. When the flanging height around the entire circumference of the tube or the entire top of the plate reach the required value, then it's aligned.
After hot melt butt welding, the connector shall be fixed in the hot melt butt welding machine, and cooling the connector according to cooling period which specified in the regulations of pressure maintaining and cooling of hot melt butt welding machine. After the cooling, reduce pressure to zero, and then remove the welded pipe/fittings.
