Twelve Quality Problems and Solutions of PE Pipe

Twelve Quality Problems and Solutions of PE Pipe

Some unexpected quality problems often occur in the production process of PE pipes, which are generally caused by problems with equipment or raw materials. The following shandong wenyuan building materials will be based on years of experience in pe pipe production one by one to introduce common pe pipe quality problems and the causes of quality problems and solutions. Waviness on the surface of the 1. pipe. Reasons: 1. Insufficient cooling 2. Inappropriate size of sealing ring, resulting in vibration. Solution: Increase the water intake of the sizing sleeve or increase the distance between the mouth and the sizing sleeve. Check whether the size of the vacuum groove sealing ring is small. If it is small, replace or appropriately reduce the vacuum degree of the first vacuum groove to increase

Can PE water supply pipe and PE gas pipe be mixed?

Can PE water supply pipe and PE gas pipe be mixed?

PE water supply pipe and PE gas pipe production implementation standards are not the same, the pipeline pressure is not the same, environmental protection standards are also different, so it is not universal. PE water supply pipe implementation standard GB/T13663-2000 international polyethylene pipe (polythylenepipe) material is divided into PE32, PE40, PE63, PE80, PE100 five grades, and used for gas pipe and water supply pipe material is mainly PE80 and PE100. China's polyethylene pipe special material is not graded, which makes the domestic polyethylene gas pipe and water supply pipe manufacturers to choose raw materials more difficult.

PE water supply pipe you must know the knowledge

PE water supply pipe you must know the knowledge

PE water supply pipe is commonly used in municipal engineering. It is often necessary to find suitable manufacturers to purchase pipes that meet the requirements of the project. When asking the manufacturers, it is often necessary to provide specific parameter requirements. Many people do not understand the common knowledge of PE water supply pipe. Here, Runshuo Pipe Industry composes a general knowledge of PE water supply pipe: What types can PE be divided into according to the density of resin? Answer: PE can be divided into: low density polyethylene LDPE(0.9~0.93g/cm3) composed of homopolymer of ethylene monomer according to the density of resin; Medium density polyethylene MDPE(0.93~0.94g/cm3) consists of B

Water seepage performance of PE pipe

Water seepage performance of PE pipe

The seepage performance of PE water supply pipe has important theoretical significance and practical value, and the commonly used test methods to study PE seepage performance are immersion weighing method and differential pressure osmosis method. The soaking weighing method is to soak PE in a water container with controllable temperature until it is saturated, then place the saturated sample in an oven with the same temperature for desorption, weigh once at intervals during the whole process, and then obtain the weight and time data of the whole process to evaluate the water permeability of PE water supply pipe. This method is the basic method to determine the water permeability, the equipment is simple, low cost, so it is widely used in practice. The differential pressure osmosis method is the benefit.

The difference between high and low pressure PE pipe

The difference between high and low pressure PE pipe

High pressure is obtained by reaction under high pressure, and the corresponding low density PE, that is, LDPE low pressure is polymerized under lower pressure, and the corresponding high density PE, that is, HDPE, is obtained. Generally its density is 0.92~0.97. The high density seems to be in the range of 0.95~0.97. Garbage bags, plastic film, shed film, cling film are LDPE, all kinds of bottles. Can. A basin. Containers such as barrels, fishing nets and strapping belts are all HDPE. I have the following processing characteristics of LDPE and HDPE. Comparative LDPEHDP on Processing Characteristics of PE Pipe LDPE and HDPE

PE pipe PVC pipe PP pipe PB pipe how to distinguish

PE pipe PVC pipe PP pipe PB pipe how to distinguish

Compared with the characteristics and main uses of several plastic pipes, PVC pipes have better tensile and compressive strength, but their flexibility is not as good as other plastic pipes, their corrosion resistance is excellent, and their price is the cheapest among all kinds of plastic pipes. However, CPVC pipes have outstanding heat resistance at low temperature, such as brittle bonding, socket rubber ring connection, flange thread connection, water supply and drainage, irrigation, gas supply and exhaust pipes, wire pipes, rainwater pipes, industrial anti-corrosion pipes, etc, the thermal deformation temperature is 100 ℃, excellent chemical resistance, bonding, flange threaded connection hot water pipe, PE pipe, light weight, good toughness, good low temperature resistance, non-toxic, and cheaper,
