The invention provides a stainless steel oil pipe joint device. The device comprises a stainless steel oil pipe, a stainless steel oil pipe pier head, a stainless steel oil pipe joint and a fasteningpart; one end of the stainless steel oil pipe is connected with the stainless steel oil pipe pier head, the end of the stainless steel oil pipe joint is provided with a conical concave hole, the stainless steel oil pipe pier head is inserted into the conical concave hole, the stainless steel oil pipe pier head is provided with a non-spherical outer surface in seal fit with the conical concave hole, through the fastening part, the stainless steel oil pipe pier head and the stainless steel oil pipe joint are connected, through the fastening part, the stainless steel oil pipe pier head and the conical concave hole are in sealed fit, and a through oil conveying channel is formed in the stainless steel oil pipe, the stainless steel oil pipe pier head and the stainless steel oil pipe joint. According to the stainless steel oil pipe device, the non-spherical outer surface, in seal fit with the conical concave hole, of the stainless steel oil pipe pier head is used so that and under the condition that a stainless pipe does not use the rubber seal ring, the good seal effect is achieved.
Description
technical field [0001] The invention relates to a connection device, in particular to a stainless steel oil pipe joint device. Background technique [0002] The stainless steel oil pipe joint device is mainly used for high-pressure and corrosive liquids. The liquid in the steel pipe is corrosive, and will corrode the rubber sealing ring or gasket during use, causing accidents. Therefore, the tightness of the steel pipe joint is highly required. [0003] Existing stainless steel connection technologies such as compression / union and flange connections all require sealing rings or gaskets. When stainless steel pipes transmit high-pressure corrosive liquids, it is inevitable to corrode rubber and cause leakage. Contents of the invention [0004] The technical problem to be solved by the present invention is to provide a stainless steel oil pipe joint device without sealing rings or gaskets in order to overcome the defect in the prior art that the steel pipe liquid will corrod...
