China PVC Pipe rapid development of these
years , the annual increase rate reaches 8 percent , while the rate of increase
of 2% per year . In the plastic pipe , PVC pipe has always been ahead of the
amount , which is widely used in water supply and drainage .
Product innovation remains to be progress -
because of relatively sophisticated skills in recent years, PVC water pipe
invested little in product innovation , relatively few new products, more
products on the market in general , high-skill , low value-added products ,
similar generic products, the majority of low-grade products , less advanced
products.
Effects of lead on the ban PVC-U pipes -
probably face is , PVC-U water pipe to use non- lead salt rule of PVC heat
stabilizers pipeline industry a greater negative impact . Although the part of
industry associations and a number of production companies make a lot of
efforts, held a special press conference to promote the use of the media , the
whole situation gradually rational, but because some users of the real
situation is still not very aware , PVC-U the rate of increase is less than the
amount of drinking water pipes to increase the level of uniformity , but also
for the use of other PVC-U pipes are also potential negative effects.
Extended use areas , stone
coated metal roofing tile market operations to be progressive
implementation , application and supporting skills need to be further improved
- to promote the industry and products , science and other aspects of the job
are not in place , the impact of the expansion of the use of plastic pipes and
rational use areas . Industry associations about the job remains to be
progress, more needs to strengthen efforts to promote implementation .
Currently, the market will set the product 's use in a limited number of areas
, as well as use the opportunity to open up new markets . Some products use
matching skills are not available, and some product design , construction,
testing and other standardized operations lagging behind.
Market is not standard , and some
low-quality product quality , impact on the healthy development of the industry
- because the plastic pipe market is not standard , and some buyers are not the
end use of the product who do not pay attention to the brand and quality , the
formation of the market is not the same quality together with the presence of
the product , and even some low post when the geological disposal of the
product is very good , and PVC-U pipes quite serious . It knows that a company
produces a variety of PVC-U county region has 500 or more, and the vast
majority of family workshops , Quality imagined. Capital PVC-U pipes , the
material quoted accounted for about 70% of the wall thickness is reduced
through a single company , a lot of calcium carbonate and other methods to
increase product costs decline , the formation of low-quality product quality.
There are not two or more companies to use the same trademark quality , the use
of low- level processing equipment , water pipes and other selection methods
lead salt stabilizer production to reduce costs , harm the interests of
consumers , ruined the industry 's promise.
Should further improve the quality of
construction works - PVC-U pipeline project depends largely on the level of
construction quality , good stone coated metal
roofing tile product cordial construction ensure
outstanding talent pipeline operation systems engineering . Some engineering
skills shortage of professional staff training, follow metal tube method in practice
for design and construction , there is a situation of non-standard construction
, rough construction , etc., not fully PVC-U pipes skill economic function ,
and even the formation of the pipeline damage. Some users still do not know the
current plastic pipe according to the rules of knowledge about how throughout
the construction and supervision .
