High Temperature resistant fire sleeve widely serves in petrochemical industry
PE material is polyethylene, which is the largest type of plastic material. It is a polymer material synthesized from polyethylene. There are basically two categories: low density polyethylene LDPE (lower strength); High density polyethylene HDPE. PE materials are divided into five grades according to the international unified standards: PE32, PE40, PE63, PE80 and PE100.
The production of PE pipes for water supply pipes is high-density polyethylene HDPE, graded as PE80 and PE100 (according to the minimum required strength MRS). The MRS of PE80 reached 8 MPa; The MRS of PE100 reaches 10MPa. MRS is the tensile stress strength of the tube (calculated according to international standards).
PE pipe is medium density polyethylene pipe and high density polyethylene pipe. According to the wall thickness, it is divided into SDR11 and SDR17.6 series. The former is suitable for conveying gaseous artificial gas, natural gas, liquefied petroleum gas, the latter is mainly used for conveying natural gas. Compared with steel pipe, the construction process is simple and has a certain flexibility. More importantly, it is not used for anti-corrosion treatment, which will save a lot of process. The disadvantage is that the instrument is not as good as steel pipe. Construction should pay special attention to the safe distance of heat heating, can not be exposed to the sunlight in the air, sensitive to chemicals, to prevent the leakage of sewage pipes.
PU pipe has excellent high pressure resistance, vibration resistance, corrosion resistance, wear resistance, weather resistance, bend resistance, light weight; PU pipe is easy to use and flexible, the pipe is convenient to work, and the inside and outside diameter size is high precision; PU tube has flexibility, durability, flexibility, easy to use, excellent thermal insulation, superior bending performance!
The types of PU tubes produced by our company are PU tubes, PU braided tubes, PU pneumatic tubes and PU hoses. The main properties are: wear resistance, impact resistance, corrosion resistance, bending resistance, low temperature resistance, crack resistance, long service life, good elasticity, safety and reliability. It has a wide range of applications, such as food factory, industrial plant, fishery, medical, weaving machinery, ceramic machinery, packaging machinery, printing machinery and so on.
