Grooved pipe system introduction

　　Haolong grooved pipe attachment makes the installation of the pipeline system become simple ,convenient and reliable . Grooved pipe system is the most economic pipeline connected ways.In the fifties,it was popularized and applied on a large scale in America. This installation way is faster than flange and whorl , and it doesn't damage pipeline layer.So it avoids welding zinc-plated two times and make the whole pipeline installation cost drop the lowest.

　　HaoLong pipe attachment cast caliper , high extending rate of Check Hoop of ductile cast, The high power joining bolt produce according to CJ/T156-2001.To every batch products carry on checking ofchemistry and mechanical character, and to cast caliper carry on checking of mechanical character and resist aging .It guranteed the security of pipe fittings and seal useing.

      Haolong grooved attachment except the advantages of making pipeline installation system fast. Its connection has flexibility and antidetonation , resist expanding and shrinking ability.It allow steel pipe have certain relative deflections , it is easy to adapt to the deformation of the steel construction main building ,and guarantee the pipeline system not out,this is also the adopting character of architectural design.

      Haolong grooved attachment makes the pipeline system become the most convenient pipeline system of maintaining , it can revise and change the pipeline condition convenient .If only unclamp two slices of calipers ,It can change a section of steel pipeand reduce maintenance person and cost greatly , it will offer the related tool of perfect construction to the customer.
