Company Introduction:
Our company, Qingdao Judibode trading CO. Ltd. Is a large and professional manufacturing company.
Our main products are as below:
1, Ductile iron pipe fitting according to EN545/ISO2531/ANSI AWWA C110/153 from DN50 to DN2000
2, Ductile iron pipe joint, include but not limited to Universal couplings, universal flange adaptor, Gibault joint for PVC pipe, Quick flange adaptor for PVC/PE pipe, Saddle for PVC pipe, Universal saddle with SS band., Flange adaptor and coupling for PE/PVC pipe, dismantling joint, repair clamp, expansion joint etc. All of them are according to EN545/ISO2531/AWWA and PN10/PN16/PN25/PN40/ANSI B16.5 Class 125/150
3, Ductile iron valves, include but not limit to gate valve, check valve, angle valve, air release valve, hydraulic control valve etc.
For surface treatment, beside Epoxy Resin power coated, Nylon coated also available.
Our market: Europe, USA, Middle-east, Africa and South-America.
5; Our capacity: 500tons/month.
We are most professional supplier in China for ductile iron pipe joint(coupling, flange adaptor, dismantling joint, gibault joint, saddle clamp, repair clamp etc) and OEM pipe joint, and we are the only one who produce them on auto production line in China. Then our price is much lower and quality is better for higher pressure. And surface is more smooth and beautiful.
Welcome all clients come to check our foundry, we will do our best to support.
