KDF High Pressure Flexible Rubber Joint
Introduction:
KDF High Pressure Flexible Rubber Joint consist of fabric reinforced and matal flange loose joint,used on shock decrease, compensate for displacement.KDF means flanging high pressure rubber joint ,JGD dual ball rubber joint,JGD-B threaded dual ball joint,which have functioin as high flexiblity,resistance to media and climate , also called rubber joint , shock absorber, pipe shock aborber , but all mean high pressure flexible rubber joint.
The product is mainly large-sized, large diameter, high-pressure rubber joints, "KDF-DN3000 large high-pressure flexible rubber joints," win "high-tech product certificate", and was recognized as "scientific and technological achievements of Henan Province." This product is our patent product, patent No.: 98210707.2. The main characteristics of the sphere with the wrapping rubber flange, can increase connection with the sealing metal pipes, but also increase the pressure of the product during use, prevent pull off.
[Chatacter]With high pressure, good elasticity, displacement volume, balance pipe error, absorb vibration, reduce noise, effective, and easy to install.
[Application]Can be used in water and wastewater, recycled water, HVAC, fire fighting, paper, pharmaceutical, petrochemical, shipping, pumps, compressors, fans and other piping systems, use of units such as power plants, water plants, mills, water companies, engineering and construction
[Media]Common type used to transport -15-- 115 centigrade air, compressed air, water, sea water, oil, acid and alkali. Special type used to transport -30--250 centigrade over the medium or oil, strong alkali acid concentration, solid-state materials.
[Recommendation]Good value and Cost are key indicator when pruchase products ,sino south korea joint venture obviously introduce ur advanced and leading technology and science , start produce in 1988 , approved by ISO 9001:2000, products are used on keyp projects , and self decided export to South Korea,USA,SPAIN,ITALY,UAE,BRAZIL etc.strictly material pruchase ,serious inspection,strong sales network ,cost effective offer lead us large marketshare , meanhwhile well secure your construction project .We warmly welcome your esteemed company visit us and guide work any time !
