China National Standards Drafting Unit of Rubber Joint
Qualified Joint Supplier in Nuclear Power Plant


We invented clamp type rubber joint to meet clients' demand in 2002 and replaced flange and bolt with clamp. the two nozzies of clamp rubber joint can be easily installed around relevant pipes and the rubber joint and pipe can be fixedby clamps, and loose the clamp for maintenance so as to compensate the displacement resulted from pipes'hot expansion and cold constriction. Compared with other rubber joints, the product has characteristics as follows: 
1. Clamp rubber joint saves flange and bolt and reduces project expenses; 
2. Clamp rubber joint nozzie needs no flanging, which simplifies production procedures for rubber joint and savesraw materials. 
3. Clamp tye rubber joint simplifies installation and maintenance and improves work resistance.
