Embodiment
The utility model is further illustrated below by the mode of embodiment, but is not therefore limited in the utility model
Among described scope of embodiments.
As shown in Figure 1 to Figure 2, the utility model provides a kind of stainless steel oil pipe piecing devices, and it includes stainless steel oil pipe
1st, stainless steel oil pipe pier nose 3, stainless steel oil pipe joint 4 and secure component 2；One end connection stainless steel oil pipe of stainless steel oil pipe 1
Pier nose 3, the end face of stainless steel oil pipe joint 4 have conical indents 43, and stainless steel oil pipe pier nose 3 is inserted in conical indents 43, no
The steel oil pipe pier nose 3 that becomes rusty, which has to seal with conical indents 43, coordinates non-spherical surface, secure component 2 by stainless steel oil pipe pier nose 3, no
Rust steel oil connection 4 connects, and stainless steel oil pipe pier nose 3 is sealed with conical indents 43 and coordinates, stainless steel oil pipe 1, stainless steel oil
Pipe pier is first 3, stainless steel oil pipe joint 4 is internally formed the oil transportation channel run through.
Above-mentioned stainless steel oil pipe piecing devices, mainly pass through the non-spherical surface and stainless steel oil of stainless steel oil pipe pier nose 3
The conical indents 43 of pipe joint 4 coordinate, and reach sealing effectiveness.
