-56 will tolerate a maximum differential pressure of 1000 psi. Note that the maximum pressure that the P55 or DP15 sensor can contain is 4000 psig! So the -64 range, with a full scale of 3200 psi differential will likely leak once the over pressure reaches 4000 psig – somewhat less than twice the full scale range of the transducer. Line Pressure:


For required pressure and coverage of ground, the parameters such as gross weight of the roller, the area of each foot, the number of lugs in contact with the ground at any time and total number of feet per drum are considered. The compaction of soil is mainly due to foots penetrating and exerting pressure on the soil.

Rulmeca, keenly aware of this requirement, has subjected and examined their design of manufactured rollers to severe laboratory tests. Numerous examples of plant and equipment used in material handling, all over the world, operating in the most severe environmental conditions, have used Rulmeca rollers of various types for many years.


Pressure Soil Compaction Soil compaction is defined as the method of mechanically increasing the density of soil. In construction, this is a significant part of the building process. If performed improperly, settlement of the soil could occur and result in unnecessary maintenance costs or structure failure. Almost all types of building sites


The welded seam is then passed through a high pressure roller which helps create a tight weld. The pipe is then cut to a desired length and stacked for further processing. Welded steel pipe is a continuous process and depending on the size of the pipe, it can be made as fast as 1,100 ft (335.3 m) per minute.

Yankee dryer - Wikipedia

A Yankee dryer is a pressure vessel used in the production of machine glazed (MG) and tissue paper.On the Yankee dryer, the paper goes from approximately 42–45% dryness to just over 89% dryness. In industry, MG cylinders or Yankee dryers are primarily used to remove excess moisture from pulp that is about to be converted into paper.


Apr 16, 2017· During the 1950s–1970s, dry granulation was mainly performed by slugging; however, nowadays, roll compaction is the preferred method because it offers greater production capacity, and simplified ...

Road roller - Wikipedia

A road roller (sometimes called a roller-compactor, or just roller) is a compactor-type engineering vehicle used to compact soil, gravel, concrete, or asphalt in the construction of roads and foundations.Similar rollers are used also at landfills or in agriculture. Road rollers are frequently referred to as steamrollers, regardless of their method of propulsion.


Therefore, in actual production, it will be found that the peel strength of 5-15mm on both sides after the composite film is matured is very poor, which is caused by excessive pressure of the rubberized roller. Therefore, in actual production, the pressure of the rubberizing roller should not be too large in the case of ensuring that the ...
