PROBLEM TO BE SOLVED: To provide a fluid pipe connection structure for fluid equipment, ensuring high and stable sealing performance in a simple structure without creating a liquid stay portion. SOLUTION: This structure comprises a connection portion 21 of an equipment body 20, having inner periphery screw portion 23, annular portion 25 with its diameter smaller than that of the inner screw portion and an annular compression bonded portion 30 formed outside a body flow passage 22, mounting member 40 having an inner cylinder portion 41 and an outer periphery screw portion 42, and fluid pipe 50 with its end as a turnaround curved portion 51 which is turned around outwardly. When the mounting member, on which the fluid pipe is mounted, is threaded and tightened to the connection portion the turnaround curved portion 51 of the fluid pipe is pressed into contact with the annular press contact portion 30 of the connection portion, and the turnaround curved portion is pressed at or around its free end 52 against the small- diameter annular portion 25.
