FIELD: testing equipment. ^ SUBSTANCE: group of inventions refers to mechanical load tests of pipe specimens (method, pipe specimen mechanical loading installation, use of method and device). Device includes at least one packer (P) located in specimen (ET) in test area (ZT) and having longitudinal dimension that exceeds length of this test zone (ZT) and including i) the first pressure creating device (C1), for local change of diametre at least of one first part of packer (P), for its being pressed down to internal surface of specimen (ET) at the level of test zone (ZT), ii) the second pressure creating device (C2) intended for applying the first chosen internal pressure to some part of inner surface located at the level of the second part of packer (P), and/or iii) the third pressure creating device (C3) for combined action at least with one overlapping element (B1, B2) attached to the specimen at some distance from the end of packer (P) in order to specify operating zone (ZA), for applying the second chosen internal pressure to the specimen (ET) at the level of the second chosen internal pressure at the level of operating zone (ZA). Group of tested specimens can represent various combinations of pipe connections. ^ EFFECT: development of an version for static installations in which jack and medium under pressure are used simultaneously. ^ 48 cl, 8 dwg
