Connection method of circular metal pipe using press fitting (PRESS type, pressure fitting type) pipe fitting with sealing packing for airtightness of elastomer (PACKING RING)

摘要

The present invention relates to a thin-walled metal pipe (eg, KSD 3595 stainless steel pipe for general plumbing) using a food, wherein a press-type (press type) pipe for interpolating an elastic packing ring 1 to generate a sealing effect, (A copper pipe).;As the compression bonding method of the above-mentioned type of pipe fittings (for example, MOLCO-JOINT and SR-JOINT), there is a problem that the airtightness of the compression joint after the connection is not completely completed, , The applicant of the present invention intends to improve and improve the incomplete airtightness of the above-mentioned method, thereby obtaining and reducing a safe connection construction effect without leakage phenomenon.
