Stainless Double Ring Press Joint

( SP-JOINT)

[INQ. NO. 2008M02] Dasung Tech Co., Ltd. was established to improve the construction quality of stainless steel pipe joints dramatically and is playing a key part in developing the facility construction field.
On this account, of antirust, long-lasting, and hygienic stainless steel pipe joints, Dasung Tech developed the construction method of double-ring crimp-type joint that can be linked in a more convenient, safe, and economic manner without a welding process. SP-JOINT, the abbreviation of Stainless Power Joint, is a non-welded crimping style joint that links stainless steel pipes for general piping work.
For SP-JOINT, the crimping method is used on the joint unit with an exclusive crimping tool, and there are rubber rings for EPDM tap water and STS304 material of STS ring, called double-ring crimp-type joint, in the product.
