摘要： A press-fitting connection structure for pipeline defines a first mounting groove for accommodating a retaining ring and a second mounting groove for accommodating a sealing ring, making the retaining ring and sealing ring be respectively mounted in different grooves and not easily to move. The first and second mounting grooves are spaced apart, so that the retaining ring will not come into contact with and scratch the sealing ring when the press-fitting connection structure for pipeline is subjected to the force of a press-fitting tool, thereby eliminating a closing ring originally used to protect the sealing ring, which makes assembly be more labor-saving and efficient. By means of setting a plurality of retaining teeth on the inner surface of the retaining ring, the retaining teeth can be more easily buried into the outer wall of the pipe through tip ends thereof, improving the tensile performance of the retaining ring.

摘要： A crimping tool for crimping a metallic crimp ring. The crimping tool includes a first crimp die having a first curved contact surface and a second curved contact surface, the second curved contact surface spaced apart from the first curved contact surface, and a trench extending between the first curved contact surface and the second curved contact surface. The crimping tool also includes a second crimp die cooperatively engageable with the first crimp die having a first curved contact surface and a second curved contact surface, the second curved contact surface spaced apart from the first curved contact surface, and a trench extending between the first curved contact surface and the second curved contact surface. The trench of the first crimp die and the trench of the second crimp die forms an annular bead in a center portion of the metallic crimp ring.

摘要： Provided are a mechanical tube fitting for preventing bending fracture of a tube member to be joined when subjected to bending deformation, and a simple tube fitting structure including that tube fitting. In the tube fitting, a clearance between a tube member (32) to be joined and an outer pipe (12) or an inner pipe (14) which is coaxially inserted in the outer pipe (12) and gives a space between its outer surface and the inner surface of the outer pipe (12), in which space the tube member (32) is inserted, is sealed with a sealing member disposed between the outer pipe (12) and the inner pipe (14), and the above-mentioned components are fixed by caulking. The outer pipe (12) is configured to extend outwardly in its axial direction than the ends of the inner pipe (14).

摘要： A pipe and fitting coupling system includes a first pipe, a second pipe, and a joint. A receiving end of the second pipe includes a first flange, a second flange, a groove, and a sealant. The second flange extends further than the first flange. The groove is disposed at the pipe diameter and between the first flange and the second flange. The first flange has an inwardly angled face to meet the groove and the second flange has an outwardly angled face to meet the groove. The sealant is disposed in the groove to seal the plain end of the first pipe in the receiving end. The joint is formed by the cooperative alignment of the plain end being inserted into the receiving end and being sealed by the sealant.

摘要： A technique provides for combining a subsea housing, e.g. a subsea low-pressure wellhead housing, and a casing. The casing may be in the form of a large diameter conductor positioned in a seabed to facilitate deployment of desired types of tubulars and other components in a subsea well. The casing is inserted into the subsea housing along an interior surface of the subsea housing. The casing is joined to the subsea housing by radial expansion of the casing until the casing is forced into a suitable engagement with the subsea housing.

摘要： The application relates to a pipe connection having a pipe end arranged in a connection piece. The pipe connection has an outwardly projecting at least sectionally circumferential bead configured on a pipe end. The connection piece has a radially deformable first connection piece portion creating a first radially deformable connection piece portion. The pipe end is held and secured in the connection piece using the first radially deformable connection piece portion. The application further relates to a heat exchanger with a pipe connection of this kind and a connection method for producing a pipe connection.

摘要： Pipe joining compresses sleeves on abutted pipe ends. The sleeves are deformed beyond elastic limits, and the pipe ends are moved inward and exert outward forces on the sleeves. A machine has racks and an assembly of radial geared rollers which turn and compress the sleeves with grooves surfaces. Assemblies of fixed racks and assemblies of rollers on axles relatively move by hydraulic power, causing the rollers to turn and compress the sleeves.

摘要： In various embodiments a frame system for a surgical system may include a plurality of rod structures cross connected through one or more structural members. In some embodiments, the rod structures may each include at least one rod with an interface joint molded over the at least one rod. One or more of the interface joints may include a receiving hole for receiving a structural member to couple at least two of the plurality of rod structures together. One or more surgical components (such as a surgical console) may be received into the frame system. Other components may also be received into the frame system (e.g., an aesthetic skin). The rod structures may also include cross face structural members that are secured to portions of the rod structures through being molded to the rod structures through the interface joints.
