The main raw material PVC water pipe is health grade PVC resin, adding quantitative stabilizer, lubricant, filler, toner, etc., the plastic extruder extrusion molding and injection molding machine, through cooling and solidifying, finalize the design, testing, packaging process to produce a kind of water supply pipe The characteristics of PVC water supply pipes 1.Light weight, convenient handling and handling: small density, convenient handling, loading and unloading and construction. 2.Excellent corrosion resistance: excellent acid resistance, alkali resistance and corrosion resistance, suitable for the use of chemical industry. 3.Fluid resistance is small: the inner wall of the pipe is smooth, its rough coefficient is only 0.009, and the fluid resistance is small, effectively improving the hydraulic condition of the pipe network and…
PPH threading tool is used for PPH pipe thread making, mainly by the main body, thread twisted wire, card cover and core composition. Next you will learn how to assemble the PPH threading tool. 1.Take out the tool body and open the lid; 2.Cased the corresponding size of the tool; 3.Take out the corresponding size hexagonal threading die(with the words to the outside); 4.Install the fixed cover and rotate it securely.
PPR pipes are widely used in industrial and residential buildings, sanitary drinking water and hot water heating. PPR pipes are divided into 2 kinds of hot and cold water pipes. Cold water pipe thickness is thin, hot water pipe is thicker. So in the resistance to fracture, hot water pipe performance is much better and the price of hot water pipe is also more expensive than cold water pipe. Many manufacturers for the sake of insurance, the construction process regardless of hot and cold water pipe cracking, improve safety factor. The real PP-R pipe shall comply with the standards of GB/T18742-2002 ” plastic piping systems for hot and cold water –PP second part of the pipe” fittings shall conform to…
The installation steps of PPR pipe and fittings 1.Check the operating welding machine and the temperature should be up to 260 ℃ . 2.Mark PPR pipe the access depth before welding(25mm depth is about 1.5cm) 3.Parallel the pipe and fitting into the welding head for 4 seconds’ duration 4.Pulling out the pipe and fittings after fully heated and keeping a good time after the join. 5.After the temperature is cooled, the pipe is tightly coupled with the fitting. 6.To see the fusing effect, we use scissors to cut and the joints are seamless. 7.In the project pipe and fitting all installed, with the test press test pressure 48 hours without leakage, can be used normally.
1.Open the tool box and take out the bracket. 2.Take out the host, fixed on the bracket. 3.Select the corresponding size of the metal fitting, using the octagonal screw to fix the fuse 4.Connect the power supply to check if the fuser is working. 5.After the work is turned off, the fuser is still at high temperature and can wait for cooling.
PPR pipe and pipe fitting as the preferred material for water improvement of home decoration, you definitely want to know some of the basics and characteristics of the PP-R pipe and pipe fitting. The following content will lead you to a deep understanding of PPR pipe and pipe fitting, know exactly what it is. The introduction of PPR pipe and pipe fitting PP-R pipe and pipe fitting is also called three-type polypropylene pipe, which is made of random copolymerized polypropylene.PPR pipe and pipe fitting characteristics is light, corrosion resistance, no scaling, long-life etc. That is a new type of plastic pipe developed and applied in Europe at the beginning of the 90s. At the end of the 80s, PP-R…
UPVC what material? UPVC known as hard PVC, which is an amorphous thermoplastic resin plus certain additives by the polymerization of vinyl chloride monomer made (such as stabilizers, lubricants, fillers, etc.). In addition to using the additive, but also uses blended with other resins modified approach, it has obvious practical value. I believe we will have a home water pipe, whether it is a kitchen or bathroom and toilet need to use pipes, but you know your home water pipes is what material it? Now generally have metal pipes, cement and plastic categories, and for the residents of the home must take the plastic pipe mainly, at this point we may well be asked of plastic there are many, that…
PVC water supply pipe fittings are designed and manufactured in accordance with national standards, products are widely used in buildings. External water supply pipeline system. The product is soft and beautiful color, inside. Outer wall is smooth, the fluid transmission resistance is small, it is 0.6-0.7 times of the same direct cast iron pipeline system. The product is light weight. Than the high strength, pressure, impact resistance, corrosion resistance is good. Pipe Test items Index Physical properties density kg/m³ 1350-1460 Vicat softening temperature ℃ ≥74 Water absorption g/㎡ ≤40 Oven test No bubbles or splitting line cracking Mechanical properties Fall test No leakage or rupture Hydraulic test No leakage Hygiene standard Lead extraction value The first time < 1.0mg/L The…
With the rapid development of our country’s hard PVC pipe, pipe fittings production technology and construction technology and supporting fire prevention measures, especially “Code for Design of Building Drainage PVC Pipe” (CJ J29-1989) and “Building Drainage PVC Pipeline Construction and Acceptance Regulations “(CJ J30-1989) since the implementation of PVC pipe has been widely used in building drainage projects. However, mistakes often occur in the actual installation process, leading to seepage of the floor, water leakage at the joints of the pipe fittings, poor water launching and dirty indoor air, which have seriously affected the normal use of households. 1 common installation errors and countermeasures 1.1 three links or four links Due to the negligence of construction workers, the three-way or…
CPVC (chlorinated polyvinyl chloride) is a thermoplastic pipe used for potable water supply in residential construction. It’s a modified version of PVC (polyvinyl chloride) that’s made more stable and rigid through a chlorination process. The added chlorine gives CPVC better insulating properties, higher temperature tolerance, and improved resistance to fire and corrosion. CPVC pipes are available in sizes from 1/2″ to 24″ and are approved for use in plumbing and mechanical codes in the United States and Canada. The content list of this article: Advantages of CPVC Pipe Characteristics of CPVC pipe Application range of CPVC pipes Advantages of CPVC Pipe CPVC water supply pipe is based on chlorinated polyvinyl chloride resin as the main raw material, extruded by extrusion…
HDPE (high density polyethylene), English full name is High density polyethylene HDPE is a highly crystalline, non-polar thermoplastic tree fat. The appearance of the original HDPE milky white, in a slight degree of cross-section was a certain degree of translucent. PE has excellent resistance to most life and industrial chemicals. Certain types of chemicals can cause chemical attack, Examples are corrosive oxidizers (concentrated nitric acid), aromatic hydrocarbons (xylene) and halogenated hydrocarbons (carbon tetrachloride). The polymer is non-hygroscopic and has good water vapor resistance and can be used for packaging applications. HDPE has good electrical properties, In particular, dielectric strength is high, making it suitable for use in wire and cable. Medium to high molecular weight grades have excellent impact resistance…
