The invention relates to a carrying device (2) for receiving pipeline elements (4) in a surface coating installation, having a main body (6), an attachment section (28) which is formed on the main body (6) and which serves for the attachment of the carrying device (2) to a ceiling-mounted conveying mechanism, and multiple cantilevers (8) extending laterally from the main body (6). Each cantilever (8) has arranged thereon a receptacle (10) with support feet (12, 12) arranged in pairwise fashion and spaced apart from one another, wherein the support feet (12, 12) are configured to come into contact with in each case one outer wall section of a pipeline element (14) in order to hold the pipeline element (14) between the support feet (12, 12).

A coating booth (101) for elements to be coated. The coating booth (101) comprises a passage between opposing vertical sides (107a, 107b, 108a, 108b) through which elements to be coated are conveyed. There is an entrance (105) at one end of the passage and an exit (106) at the other end of the passage. The coating booth (101) comprises a conveyor line (102) for supporting said elements to be coated and configured to convey said elements from the entrance (105) to the exit (106) along a straight pathway, and, a suction system. The opposing sides of the channel are symmetrical about the pathway. Sets of spray guns (103a, 104a, 103b, 104b) for spraying coating powder at the elements are positioned symmetrically either side of the straight pathway. The suction system comprises vertical suction inlets (109a, 109b) mounted opposite one another on each opposing vertical side of the passage, the suction system being configured to provide equal amounts of suction through each of the opposing vertical suction inlets (109a, 109b).

A system for coating a heat transfer tube for a condenser is disclosed. The system simplifies a process of coating the heat transfer tube, and is able to uniformly coat a plurality of heat transfer tubes. In addition, the system is economically feasible in that coating solution can be reused by collecting and circulating it. Due to super-hydrophobic coating, the size of a droplet condensed on the surfaces of the heat transfer tubes coated by the system can be reduced, and a condensation heat transfer coefficient can be increased.

A pipe conditioning tool comprising a drive unit to move the tool along a pipe and a work head rotatable about an axis of the pipe to condition a surface of the pipe, the drive unit includes a frame extending to opposite sides of the pipe, the frame having legs extending radially beyond the work head to provide support for the tool upon removal from said pipe.

An apparatus for coating an object or component includes at least one dispenser for dispensing a falling flow of material and an actuator for projecting the component through the falling flow of material. A landing may also be provided for receiving the coated projectile, the landing adapted for providing a second coating to the coated projectile. Related methods are also disclosed.

Systems and methods are provided for securement of parts. One embodiment is a method for securing a part during fabrication. The method includes forming an interference fit between a pin and a wall defining a hole, supporting a weight of the part with the interference fit, and rotating the part around an axis of the part while the weight of the part is supported.

An annular nozzle assembly includes an inlet tube, an annular tube, at least three first spray nozzles, and a plurality of separating vanes. The annular tube connects to the inlet tube. The first spray nozzles are fixed to the annular tube and are directed to spray inwardly and in a first vertical direction and are equally spaced from each other. The separating vanes are disposed within the annular tube and extend along a length thereof and define a flow channel for each first spray nozzle.

In a method for lacquering pencils by the push-through method, a respective pencil is guided through a lacquering chamber in order to apply a lacquer coat. After exiting the lacquering chamber, successive pencils butt against one another and are held against one another at their end sides such at a plurality of pencils form a stable strand which is guided, subsequent to the lacquering chamber, through a drying section, with the result that a respective pencil is held in a hovering manner on leaving the lacquering chamber. It is hereby in particular also made possible to use UV-curing lacquers, with the overall result that a very short total lacquering time for lacquering pencils, in particular cosmetic pencils, is achieved.

Provided is a coolant spray module system for a heat treatment metal product, comprising: a first coolant spray module (1A), wherein the first coolant spray module (1A) comprises a first module housing (10), a first module cover (20), and a first nozzle (30), wherein the first nozzle (30) is fixed between the first module housing (10) and the first module cover (20) by first nozzle fixing blocks (13) and second nozzle fixing blocks (23), wherein the coolant spray module system sprays the coolant onto the heat treatment metal product to quench and clean the heat treatment metal product.
