The Details Of Black Steel Pipe

The time of issue:2014-2-13 9:15:47       Author:

HDPE is a kind of high crystallinity, nonpolar thermoplastic resin. Square one HDPE appearance is milk white, in a small cross section in a certain degree of translucent of black steel pipe. PE has excellent resistance to the most of the life and the characteristics of industrial chemicals of blace steel pipe. Some kinds of chemicals can produce chemical corrosion, such as corrosive oxidant, aromatics and halogenated hydrocarbon especially high insulation dielectric strength, make it will suit for the wire and cable. At the level of high molecular weight has excellent impact resistance, even at the temperature under 40 f low temperature are so in the room.

The different processing methods of manufacturing PE available is very wide. Such as sheet extrusion, film extrusion, black steel pipe or profile extrusion, blow molding, injection molding and plastic. There are a lot of purposes of extruded PE, such as wire, cable, hose, pipe and profile. Black steel pipe applications range from small section yellow tube to forty-eight in diameter thick wall used for industrial and urban pipeline clarinet. Large diameter hollow wall work for rainwater drainage pipe made of concrete and the rapid growth in other substitutes sewer pipes.

Type plate and thermoforming, many large picnic cooler thermoforming lining is made of PE, which has high resilient, light weight and durability of black steel pipe. Other sheet and thermoforming products include fenders, tank linings, disc basin cover, transport tank and tank. A large number of fast-growing mulch or bottom sheet application of the village, which is based on the MDPE resilient, chemical resistance and impermeability. Blow molding which sold in the United States above 1/3 is used to blow molding applications of this kind of black steel pipe. These range from bleach, milk, oil, detergent and distilled water bottles to large refrigerator, car fuel tank. Blow molding grade characteristic parameters, such as melt strength, ES - CR and toughness, and used for sheet and thermoforming application level similar to that of similar grades can be used.

Usually used in the manufacture is the injection, blowing smaller containers used for packaging drugs, shampoo and cosmetics. One advantage of this process is the production automatic bottle to edges of these black steel pipes, need not be late dressing like general blow molding processing steps. It is the Injection, because of the innumerable applications of the HDPE, ranging from reusable thin-wall drink cup to 5 - the GSL cans, 1/5 of the consumption and production of HDPE of black steel pipe in domestic. Injection grade general melt index of 5 ~ 10, has toughness lower grades and liquidity has machinability of higher liquidity level. USES include daily necessities and food thin-wall packaging; Resilient and durable of food and paint; High environmental stress cracking applications, such as small engines fuel tanks and 90 - gal garbage cans.
