Provided is a steel pipe joint device. The steel pipe joint device disclosed herein comprises: a first joint pipe coupled to one end of a steel pipe; a second joint pipe inserted into and coupled to the first joint pipe; a shear key for connecting the first joint pipe and the second joint pipe; a first fixing part for fixing the shear key to the first joint pipe; and a second fixing part for fixing the shear key to the second joint pipe.

The utility model discloses a dental after tooth bonding's shearing adhesive strength testing arrangement belongs to involve material testing technical field, including support board, the support board is fixedly connected with mounting panel, the outside fixed connection of electric push rod has electric push rod, the piston rod end fixed connection of electric push rod has vertical board, the outside mounting of vertical board has thrust sensor, in the shearing force test process, still can rotate through the first twist seat that torque test motor drives to carry out, and the first twist seat will drive the tooth that contacts the contact board to rotate under the condition of rotating, and all carry out slight rotation deviation in each rotation process, simulate the slight deviation phenomenon that will appear in human body occlusion process, further increase the diversity of strength test, increase data result to make the test result more in line with the use environment in human body use process.

A prosthesis including a UHMWPE core and a coating, wherein the core is a cup-shaped core having a concave first side and a convex second side, wherein the UHMWPE has a weight average molecular weight that is from 2x106 to 3x106 grams per mole. The core has a tensile strength that is from 35 to 50 MPa. The coating layer coats the second side of the core. The coating includes titanium powder having a D50 particle size of from 200 to 250 microns. The coating has a mean thickness that is from 200 to 500 microns. The prosthesis is an acetabular cup prosthesis. When tested for abrasion resistance, the coating loses less than 65 milligrams when abraded for 100 cycles. The coating has a static shear bond strength that is from 15 to 25 MPa and a static tensile bond strength that is from 14 to 25 MPa.
