Several advantages of glass steel pipeline with insulation:

(1) corrosion resistance: chemically inert material,excellent corrosion resistance, and can according to thedifferent choice of corroded pipeline conveying medium.

(2) high mechanical strength: water pressure resistance,resistance to external pressure strength and impact strength were good and according to requirements of thedesign and manufacture of pressure pipes and pipe fittings.

(3) temperature adaptability: use temperature range:more than -70 degrees Celsius lower than 250 degrees Celsius, the freezing medium pipeline without crack.

(4) small fluid resistance: pipeline smooth inner wall,roughness coefficient is 0.0084, the same flow, pipe diameter can be reduced.

(5) light weight, long service life, light weight, convenient transportation, low cost, no maintenance, the service life of 50 years or more.


Q:What belongs to plastic profiles
Plastic profiles are used more: window frames, staircase handrails, troughs, wall feet, shaped tubes and so on. Raw materials are mainly hard PVC, a few are semi-hard PVC, soft PVC, polyurethane low foam and other materials. Plastic profiles with its excellent thermal insulation performance is listed as one of China's key development of building materials. In the production of plastic profiles, the need to pay attention to what problems in order to ensure the quality of profiles and technology.
Q:The state of high-rise residential building doors and windows materials are not allowed to use steel profiles are expressly provided?
The state of high-rise residential building doors and windows materials are not allowed to use steel profiles should be allowed. We are a lot of these are more than 20 layers of plastic steel `` also used.
Q:Plastic doors and windows and plastic windows do not like?
Plastic doors and windows that use U-PVC plastic profiles made of doors and windows. Plastic doors and windows with wind, water, insulation and other good features. Plastic doors and windows are made of steel and steel profiles of doors and windows, steel profiles are made of plastic and steel profiles made of mixed.
Q:The main features of steel profiles
Plastic steel profile referred to as steel, the main chemical composition is PVC, it is also called PVC profiles. Is widely used as a new type of building materials, because of its physical properties such as rigidity, flexibility, corrosion resistance, excellent anti-aging properties, is usually used as copper, zinc, aluminum and other non-ferrous metals excellent substitutes.
Q:Is not aluminum alloy better than steel?
Aluminum alloy usually use copper, zinc, manganese, silicon, magnesium and other alloy elements, the early 20th century by the German Alfred Wilm invention, the development of the aircraft to help greatly, after a World War II German aluminum alloy composition is classified as state secrets. Compared with ordinary carbon steel has a lighter and corrosion-resistant performance, but the corrosion resistance is not as pure aluminum. In the clean, dry environment, the surface of aluminum alloy will form a protective oxide layer.
Q:The development of steel profiles
China's steel production capacity has reached 5 million tons / year. Most manufacturers can not fully play the capacity, there is a serious overproduction and homogenization of competition. China's steel profiles common national standard is GB / 8814-2004, access to national inspection-free enterprises are also referred to this standard production. Different from Europe and the United States, China's single type of profiles, the market is the bulk of the 60MM Pingkai doors and windows series of profiles and 80MM push-pull series of doors and windows profiles. The above two specifications account for more than 80% of the total consumption.
Q:What is the steel profile?
GB 8814-2004 according to the thickness of the main section of the profile will be divided into three categories of ABC, according to the "visible wall thickness minimum / non-visible wall thickness minimum" said, A type of wall thickness of 2.8 / 2.5mm, B Type of material requirements wall thickness 2.5 / 2.0mm, C type of wall thickness does not specify the requirements. The mainstream of the national standard profiles are Class B.
Q:What is the meaning of steel profiles 80?
Ordinary steel profiles will be deformed, the color is relatively monotonous, usually white, if you want to change the color will add PVC with the film, a long time the PVC film will fade. Automotive supplies industry in the use of steel, the material requirements are relatively high, the most typical is the engine chassis protection board, has been widely used by most riders. Plastic steel is also used in the production of tapered roller bearing cage. Plastic cage has: 1, reduce the friction and roller slip, reduce the working temperature; 2, improve safety and performance; 3, fail safe mode, not stuck.
Q:How plastic embossed profiles are made
Plastic processing is a complex process, generally divided into the following main processing methods:
Q:PVC extrusion profiles compared to ABS, PE and other plastic profiles have any advantages?
PE is polyethylene, this product is light weight, easy processing, the screw and the barrel is not too high requirements, processing temperature is wide, but the hardness is not PVC and ABS good, chemical resistance, some places as PVC.
