Water and report are decorated in the family is in the process " take cover engineering " , and this two place are absolutely cannot jerry place. The house cannot go to do poorly done work over again maintaining again after outfit foster cordial relations between countries, one have a problem is new then " open chamber to defeat abdomen " . Especially conduit respect, when more and more people are installing conduit, be to take care again.
What major owner uses normally when installing conduit is plastic conduit (PPR) , but the connection heating up frit that plastic conduit uses controls its temperature not easily, too small conference brings about temperature slack, temperature is met too high severe deterioration. At present the PPR that go up is in charge of the market to go up to also be put in very big question character in material, the plastic material of PPR canal is character " random copolymerization propylene " , the quality that this has two production of company of Basker of boreal Europe chemical industry, Germany only in the world is better, but the price is higher, at present home still cannot produce random copolymerization third rare, a few PPR of domestic are in charge of what the factory uses is the standard that Korea and itself of homebred modified model propylene do not accord with PPR to be in charge of, still have many enterprise aborning mix into a lot of other plastic, these pipe are called " PPR " canal, accordingly, these quality that provide material should be an issue that makes a person afraid quite.
Choose material of high grade stainless steel to make service pipe, already made a kind of trend on the world. Stainless steel material is the healthy material of a kind of accepted OK and embedded human body, for material with stainless steel production conduit has had in the developed country make old history. The data makes clear:
Be in Germany, the dweller of 80% above chooses the conduit of stainless steel material;
Be in Japan, tokyo already had the resident of 85% above to use the conduit of stainless steel material;
In Australia, had begun to change other canal material, convert the conduit of stainless steel material;
Be in the United States, the hose that drags Si Wei to add guesthouse of Si Wuxing class uses stainless steel data entirely.
Be in China, construction ministry provides national standard at releasing thin wall stainless steel on July 10, 2003 (GB/T19228.2-2003) . Olympic Games place and hotel of 5 stars class used thin wall stainless steel to be in charge of as life feed pipe!
So, choose stainless steel conduit what to profit there is?
1, wholesome, avirulent. Stainless steel material is the healthy material of a kind of accepted OK and embedded human body, it is material of sanitation of 21 centuries environmental protection, for material with stainless steel production conduit has had the application of result of a lot of the year's harvest to record in the developed country.
Cast-iron pipe is perishable corrode is rusty, the influence is healthy, plastic conduit easy generation has mephitis system
2, anti-corrosive, do not written guarantee dirty. The care of mark of rust of yellow spot of crock of the birdbath that because conduit is rustily,can avoid to cause, bath. Cast-iron pipe is perishable corrode is rusty, service life is brief, and conduit corrodes a knot to dirty to be caused easily jam.
3, hot coefficient of expansion. Stainless steel canal is other the 1/4 of plastic pipe product, exorbitant coefficient of expansion can cause hose when environmental temperature changes slack.
4, tensile strength. Stainless steel provides material tensile strength ≥ 530, ≥ of plastic conduit tensile strength 49, plastic kind of product strength 9.2% what be stainless steel only. Intensity inadequacy is conduit suffers outside force to affect one of slack factors.
5, the shell is beautiful. Wall of product inside and outside is smooth, fluid resistance is little, colour and lustre is downy, modelling is beautiful. Cast-iron pipe rusts easily, not beautiful.
6, join is convenient. Stainless steel canal joins means is calorie of join that press type, cost low, speed fast, operation simple, on the safe side. ABS canal material uses ABS collosol to stick receive; And cast-iron metal canal uses silk to buckle join commonly, easy leakage, conduit of other stainless steel is collected solder type join, cost is high, construction time is long.
7, ultraviolet illuminate. Stainless steel canal does not have ageing phenomenon. Plastic pipe material issues ageing in the light serious.
8, high temperature resistant. The highest use temperature that thin wall stainless steel is in charge of can amount to 120 ℃ above, lowermost temperature can be amounted to - the heat of material of canal of 20 ℃ ABS be out of shape temperature 80 ℃ , plastic kind of canal material is not high temperature resistant, the meeting when combustion produces toxic gas.
9, environmental protection function. Stainless steel canal is OK 100% reclaim. ABS and PPR canal material cannot 100% reclaim.
10, service life is long. Below long-term and continuous actuating pressure of the regulation, use next life to be able to be amounted to 100 years above casting iron pipe is perishable corrode is rusty, service life is brief, PPR is not worth the 1/4 of stainless steel.
