How much do you know about PVC PU steel wire pipes?How much do you know about PVC PU steel reinforce wire pipes?
As we all know, plastic hoses include steel wire pipes, wire pipes, hoses, snakeskin pipes, fiber pipes, high-pressure pipes, composite pipes, rubber-plastic pipes, and plastic-ribbed pipes. Today we mainly talk about PVC steel pipe.
There are many names of PVC steel pipe in the industry, PVC steel wire reinforced hose, spring tube, steel wire winding transparent tube, steel wire hose, steel pipe, etc.,
The transparent steel wire tube is also a PVC steel wire spiral reinforced hose, which is simply referred to as "steel wire tube" in the PVC hose industry. The product is made of PVC plastic as the main body, and the spiral steel wire is embedded as the reinforcement layer, so the product has both rigidity and flexibility, not only has sufficient mechanical properties and rigidity, but also has excellent flexibility. Generally, according to the performance of the hose, major manufacturers will divide it into ordinary PVC steel wire spiral reinforced hose, PVC steel wire high strength polyester fiber composite reinforced hose, food grade PVC steel wire spiral reinforced hose, PVC high temperature / low temperature resistant steel wire Spiral reinforced hose, PVC anti-static steel wire spiral reinforced hose and so on.
The main purpose:
PVC steel wire hose can be divided into industrial grade (specially conveying industrial water, oil, sewage, powder, chemical raw materials, etc.) and food grade (food factory conveying juice, milk juice, drinking water, winery conveying liquor and beer) , Etc.), liquid and solid particles, powdery materials such as wind power, suction and drainage, oil, low concentration chemicals, etc. Regardless of the purpose, the substance itself must be a "non-corrosive" "low concentration chemical" substance.
The PVC steel wire pipe is a PVC hose embedded with a steel wire skeleton. The inner and outer tube walls are transparent, smooth, and free of air bubbles, and the fluid transportation is clearly visible; resistant to low-concentration acids and alkalis, high elasticity, not easy to age, and long service life; resistant to high pressure, can maintain its original state under high pressure vacuum.
1. High elasticity, high strength galvanized metal wire, high-quality PVC synthetic material;
2. The clear and transparent tube has good flexibility and small bending radius;
3. High negative pressure resistance, corrosion resistance, non-toxic materials, long service life;
4. Used in the suction and discharge of liquid, gas, oil and dust in agricultural pump machinery, oil depots, petrochemical equipment, industry, engineering mines, food manufacturing and other fields. It can replace rubber tube in most working environment.
Identify the advantages and disadvantages
In order to meet the operational needs of various industries, the demand for steel wire pipes is increasing day by day. Many steel pipe manufacturers have been born. The PVC transparent steel wire pipes produced are varied, and the quality is also very different. How should you choose a good quality steel pipe and how to judge the quality?
In order to allow customers to avoid unnecessary economic losses in the choice, the following summarizes several methods to judge the quality of steel pipe?
1. When conditions permit, professional instruments can be used to test the heat deformation temperature or Vicat softening point, color, turbidity, positive and negative pressure resistance, bursting pressure, halogen and nitrate content of The tensile strength, etc. to determine the quality of the steel pipe.
Second, in the absence of technical conditions, you can use visual, olfactory, tactile and other methods to judge the quality of pvc transparent steel pipe quality.
a. Observe whether the wall thickness of the steel pipe is uniform. If the manufacturer allows it, it is more straightforward to sample from the middle. It is mainly to prevent fraudulent elements from falsifying during the production process. The uneven thickness of the pipe wall will lead to easy fracture and easy use during the process. Blasting seriously shortens the service life of the steel pipe.
b. The high-quality steel wire pipe should be transparent and odorless. The particles processed by special process are crystal clear and free of any impurities; on the contrary, low-quality PVC hose particles doped with impurities will appear yellow, the wall of the pipe is opaque, opaque, not Anti-aging and other characteristics
c. Observe whether there are bubbles, paste, etc. on the tube wall under good lighting conditions.
d. The high-quality steel wire odor is very small, except for the weak plastic smell, there is no irritating odor like petroleum additives. On the contrary, the low-quality steel wire odor is pungent, using a large amount of recycled materials and chemical raw materials to add As a result, especially in the season when the temperature is high, it is impossible to get close at all, and the smell is great.
e. Take a piece of steel wire from the cut surface of the steel pipe to make an experiment to see if it is easy to break. Good quality steel wire requires professional tools for cutting. In addition to ensuring its flexibility, a good quality steel wire pipe needs to be increased. Tensile strength.
f. High-quality steel pipe, smooth inner and outer walls, evenly wound steel wire, otherwise low-quality steel pipe feels rough, not transparent, etc.
