Pipe, Pipe large diameter , double-wall Pipe, Pipe Hollow , from the year 2000 the country began to introduce production equipment from abroad, domestic equipment manufacturers have developed a year of production equipment .
1 Introduction
Pipe, Pipe large diameter , double-wall Pipe, Pipe is a hollow high -density polyethylene (HDPE, PVC) as raw materials,
Welded by winding a pipe, because of its unique molding process , can produce up to three meters in diameter of the pipe, it is difficult to complete the production process of the other nylon cable tie. High-density polyethylene (HDPE, PVC) due to its own financial excellent welding performance not only ensure the molding process and product quality, but also for the construction of a reliable connection provides a variety of ways, such as electric fusion welding , heat shrink connections , etc. while this is an important reason for the leakage occurs rarely , but also precisely because of this reason, this pipe was not available with other pipes surrounded by unique features, this attention to the current pollution control provides a very effective way .
Second, the pipe performance
HDPE ( High Density Polyethylene ) double-walled large diameter pipes wrapped in HDPE as raw material, the two forming, it has the following advantages:
1 , chemical stability , acid , alkali, salt and strong , resistant to water , waste water and chemicals,cable ties corrosion, corrosion of soil rot , no rust .
2 , impact resistance , pressure , wall -shaped structure with a unique elastic deformation of large and difficult to destroy , have a very good base for any applicability .
3 , anti-aging , pipe storage and construction process can withstand the brunt of the sun , in the design and production process pipe full account of the 50 years when the material attenuation factor .
4 , wide temperature range , can be used in -50C to 60C within a temperature range without cracking and swelling leakage.
5 , light weight, the weight of the cement pipe , 1/ 10 ( equivalent water efficiency under ) without heavy construction equipment .
6 , easy connection .
7 , superior wear resistance than cement pipes, pipe wear life more than 50 years .
8 , the price of raw materials , low construction , management and maintenance costs.
9, HDPE material is non-toxic , harmless to the land , the use of renewable , environmentally friendly green products.
security seal labels cylinder made of metal, plastic Outsourcing ABS plastic, for clip spring lock body structure, lock body surface using blanching, laser type and serial number, bar code, color can be customized according to user requirements, wire diameter φ1. 8, the length can be produced according to user requirements, pulling up to F ≥ 250KG. Scope: For Customs containers, tankers, container trucks and other purposes.
