A separator device for removing particles from suspension in a fluid includes a housing having first and second apertures for ingress and egress of fluid into and out of the housing. A first separator chamber is disposed at one end of the housing. A second separator chamber is disposed at the other end of the housing. A central chamber is disposed between the first and second separator chambers. The first and second separator chambers are apertured for ingress and egress of fluid from the central chamber, and each contains obstruction means to slow the flow of fluid within the chamber.

[SUMMARY] The present invention is capable of manufacturing an integrated tee type pipe by forming a molding pipe part, with pulling a periphery of a molding hole and protruding it to the outward direction through a pressing device and a molding device, while forming a molding hole of a predetermined shape on an upper side of a straight pipe; and manufacturing a tee type pipe that ensures robustness, productivity, and workability, accordingly.

The invention relates to a method and device for making a T-branch for a pipe by joining the shaped end of the branch pipe with internal welding to the ed-ges of a hole in the main pipe. The hole in the main pipe (T) and the arcs corresponding to the main pipe at the end of the branch pipe (P) are mechanically cut by removing one solid part from the hole and two (22) solid parts from the end of the branch pipe in a dry mechanical process, in which the cleanliness of the joint areas remains weldable. The shaped end of the branch pipe (P) is placed around the hole in the main pipe (T) and the joint seam between the pipes is welded by internal welding without a welding additive. A branch hole suitable for this is made by punching perpendicularly against the central axis of the main piped so that punch (1) pushes the piece that detaches from the main pipe into the punch hole (10) of the inner support (9).

In an example embodiment, the flange 10 has one or more openings 90 for accommodating fasteners 92 for fastening the flange and tubular member (e.g., for fastening the grab bar) to a structure such as a wall, as for example shown in FIG. 6. In example embodiment as shown in FIGS. 6 and 7, flange covers 94 that extend over the flange 10, so as to cover the flange, may be used. The flange cover may be installed over the tubular member prior to the bucking, or from the opposite end of the tubular member after buckling. As can be understood, if flanges are connected to both ends of the tubular member in accordance with the example embodiment herein, the flange covers must be placed over the tubular member at least prior to the bucking of the second end portion of the tubular member. In an example embodiment, each flange cover has an opening 96 having a diameter larger than the outer surface diameter of the tubular member but smaller than the outer surface diameter of the buckled section of the tubular member. A such, the flange cover can be axially retained by the its corresponding buckled section of the tubular member. If the flange cover opening has a diameter greater than the diameter of the buckled section of the tubular member, the cover will be axially retained by the flange. The flange cover should have an appropriate area to cover its corresponding flange. In the example embodiment shown in FIGS. 6 and 7, the flange cover 94 has a radially extending surface 98 from which extends an axially extending surface 100. With this example embodiment, as shown in FIG. 6, the radially extending surface 98 covers the flange 10, while the axially extending surface 100 surrounds the flange 10.

A tubular member and flange combination includes a tubular member having a buckled section proximate an end of the tubular member. A flange is penetrated by an end of the tubular member where an end section of the tubular member is bent over the flange such that the flange is axially retained by the buckled section and the bent end section of the tubular member. A method of forming the tubular member and flange combination includes buckling the tubular member at a location proximate an end of the tubular member forming a buckled section, placing the flange over the tubular member end section such that the tubular member end section penetrates an opening of the flange, and bending an end section of the tubular member to extend over the flange, such that the flange is axially retained by the buckled section and the bent end section of the tubular member.
