Stainless Steel Pipeline of Bulge System
Bulge Connection Definition：
The technique of bulge connection , is an exclusive invention patent from ZhengKang:“a pipe joint”(ZL2004 2 0020559.2)、patent for utility models：“pipe expanding device for pipe connection ”(ZL2004 2 0021648.9).This technology draws on and absorbs looping flange and Japanese flexible connection ,which is a new type of pipeline connection technique in thin wall stainless steel pipe of security , reliability without leakage .
Bulge Connection Principle：
Roll the pipe from inside to outside with special flaring tool to form a flange ring in an appropriate placement,then put the rubber sealing ring of EPDM into pipe fittings with socket fittings, twist lock nut ,push the rubber sealing ring to achieve the sealing and connecting effects.
Bulge Connection Significant Features：
Easy Installation
Easy installation , similar to galvanized pipe , ordinary worker needs 5mins to learn the installation method
Quick Installation
Processing pipe convex ring concentrated in the fixed site.After processing , workers can install with a common wrench , the installation speed is 20% faster than other modes,50% faster than welding
High Strength of connecting
Flange structure,connection strength of pipe fitting is high, is the largest mechanical connection strength except welding
Easy to take apart ,modify and maintain
The pipe fittings are connected with thread or flange, the pipeline can be taken apart,pipe fittings can be reused to reduce the reconstruction cost.
Multistage seal
Use third degree of O-type sealing ring,multiple protection, safe and reliable without leakage
Long service life

Coated carbon steel pipePlastic-coated carbon steel pipeline is galvanizing in the pipeline's surface and adopting polymer formulation material. After plasticizing and curing , a uniform ,dense and smooth plastic coating is formed on the surface of the pipe and a steel-plastic combination is formed. It not only has the hardness as galvanized steel pipe , but also has the advantages of wear-resistance and corrosion-resistance as plastic pipe. It is a very cost-effective and green energy saving pipes for service life tops 50 years.
