Apparatus and method for friction welding appurtenances to storage tanks
Some implementations of ignition-free welding include attaching fasteners to a tank, the tank having a wall, the wall having two parallel surfaces, the fasteners penetrating only one of the parallel surfaces, wherein the tank resides within a vicinity of a hazardous material, includes securing an appurtenance to the tank using the fasteners; and does not include removing the hazardous material.
1 . An apparatus within a vicinity of a hazardous material comprising:
studs attached to a tank by a friction forge weld, the tank having a wall, the wall having two parallel surfaces, the studs penetrating within the vicinity of the hazardous material only one of the parallel surfaces; and
a bracket that is secured to the tank using the studs and a nut threaded onto each of the studs,
wherein the bracket includes a base and a flange that is fixedly attached to the base, the base having at least one fastener hole, the flange including at least one support hole,
wherein the base has a rectangular planar shape,
wherein the flange has a rectangular planar shape.
2 . The apparatus of claim 1 , wherein the base and the flange are welded together.
3 . The apparatus of claim 1 , wherein the base and the flange are integral.
4 . The apparatus of claim 1 , wherein the base has a square planar shape in which a height of the base is less than a length of the base and the height of the base is less than a width of the base and wherein the flange is fixedly attached to the base along the length of the base.
5 . The apparatus of claim 4 , wherein the flange is fixedly attached to the base along the width of the base.
6 . The apparatus of claim 1 , the base having four fastener holes, the flange including two support holes.
7 . The apparatus of claim 1 , wherein the base has a square planar shape in which a height of the base is less than a length of the base and the height of the base of less than a width of the base,
wherein the corner of each side of the base between the length and the width of the base further comprises a diagonal corner.
8 . The apparatus of claim 1 , wherein a height of the flange is less than a width of the flange, and the height of the flange is less than a length of the flange,
wherein the corner of two sides of the flange along the other length further comprises a diagonal corner.
9 . An apparatus within a vicinity of a hazardous material comprising:
a stud attached to a tank by a friction forge weld, the tank having a roof, the roof having two parallel surfaces, the stud penetrating the roof through only one of the parallel surfaces, within the vicinity of the hazardous material; and
a bracket that is secured to the roof of the tank using the stud and a nut threaded onto the stud,
wherein the bracket includes a base and a flange that is fixedly attached to the base, the base having at least one fastener hole, the flange including at least one support hole,
wherein the base has a rectangular planar shape,
wherein the flange has a rectangular planar shape.
10 . The apparatus of claim 9 , wherein the base and the flange are welded together.
11 . The apparatus of claim 9 , wherein the base and the flange are integral.
12 . The apparatus of claim 9 , wherein the flange is fixedly attached to the base along the length.
13 . The apparatus of claim 12 , wherein the flange is fixedly attached to the base along the width.
14 . The apparatus of claim 9 , the base having four fastener holes, the flange including two support holes.
15 . The apparatus of claim 9 , wherein the base has a square planar shape in which a height of the base is less than a length of the base and the height of the base of less than a width of the base,
wherein the corner of each side of the base between the length and the width of the base further comprises a diagonal corner.
16 . The apparatus of claim 9 , wherein a height of the base of the flange is less than a width of the flange, and a width of the flange is less than a length of the base,
wherein the corner of two sides of the flange along the other length further comprises a diagonal corner.
17 . An apparatus within a vicinity of a hazardous material comprising:
a stud attached to a tank by a friction forge weld, the tank having a bottom, the bottom having two parallel surfaces, the stud penetrating the bottom through only one of the parallel surfaces, within the vicinity of the hazardous material; and
a bracket that is secured to the bottom of the tank using the stud and a nut threaded onto the stud,
wherein the bracket includes a base and a flange that is fixedly attached to the base, the base having at least one fastener hole, the flange including at least one support hole,
wherein the base has a rectangular planar shape,
wherein the flange has a rectangular planar shape.
18 . The apparatus of claim 17 , wherein the base and the flange are welded together.
19 . The apparatus of claim 17 , wherein the base and the flange are integral.
