2" Diam Heavy Duty Flexible Exhaust Pipe (per metre)

Product Information

As the corrugated interior tube is seamless, stainless steel conduit is ideal for use with liquids or gasses under pressure, especially when fitted with external braiding. With first-rate corrosion resistance, a stainless steel flexible conduit is also ideal for use in chemically demanding situations – and this combination of factors makes them absolutely perfect for use in the petrochemical industry, or in steelmaking, chemical smelting, the automotive industry the power generation industry and dozens more. The flexible stainless steel hose manufactured at Proflex Hose is suitable for use with both liquids and gases in a variety of intensive applications. As a stainless steel conduit, it is highly resistant to heat and can be used in high-temperature roles, while also being very resistant to corrosion. This corrosion resistance gives flexible stainless steel pipe the ability to survive in tough environments and carry a range of fluids. A tough, resilient and long-lasting material, stainless steel flexible conduit is perfect for use in a wide range of applications. Flexible Metal Hose

In 1913, and 1930, Marston published his original papers “The Theory of Loads on Pipes in Ditches and Tests of Cement and Clay Drain Tile and Sewer Pipe” and “The Theory of External Loads on Closed Conduits in the Light of the Latest Experiments,” respectively, marking the earliest systematic approach of studying the structural mechanics of buried pipes. Thus was defined the Marston Theory of Loads on buried conduits. A positive embankment installation condition, where the pipe is installed underneath an embankment, in shallow bedding, with its top projecting above the surface of the natural ground, is another commonly-encountered scenario for buried pipe design and installation. The loads and shearing forces just discussed for trench conditions also play a key role in embankment conditions. As indicated in figure 3a and 3b, the imaginary vertical planes extending upward from the sides of a buried pipe are the planes along which relative movements are assumed to occur and on which shearing forces are generated. The hose should not be subjected to twisting; Also, the installation should be such that flexing takes place only in the plane of bending.

Master’s thesis, Dalian University of Technology The end fitting material does not need to be the same as the hose – carbon steel fittings with stainless steel hose is a common choice. You may specify any weldable material for the end fitting or a screwed fitting welded to the hose and any threaded fitting coupled to it.

Sharp bends should be avoided while installing flexible hoses. The Technical Data Section of the vendor catalog should be followed to maintain the minimum centerline bend radius for intermittent flexing.Type 316 Stainless Steel Flexible Hose is available where even greater corrosion resistance is required The allowable bending radius for the hose depends on the type of motion the hose will experience, this is described as: Multi-layer pipes, and the Tectite flexible metal system, offer a flexible plumbing solution combined with the performance and reliability provided by the traditional metal systems Pegler Yorkshire is renowned for. From tees to tap connectors, the Tectite Classic range includes all of the fittings you need to install a high quality domestic system Hong Guo, Yan Qu, Qingzhen Lu, Jun Yan, Qianjin Yue (2011) Structure design of umbilical for deep water subsea production system.

With this form of hose, an external layer of braid is added to prevent the elongating of a tube when pressure is applied. This enables better flexibility and movement for the hose.

If desired, they can be constantly monitored by embedded sensors and electrical heating wires into the structure. Our pigging solutions, pipeline products, and structures are designed to interface perfectly with our flexible pipes. The critical plane is the horizontal plane through the top of the pipe when the fill is level with its top. At critical plane, H=0. During and after construction, if this critical plane settles more than the top of the pipe, as shown for rigid pipe in figure 3a, the settlement ratio is positive (prsd>0). For flexible pipes, figure 3b, the critical plane settles less than the top of the pipe, indicating the settlement ratio is negative (prsd<0).bar 30 °C - 6 bar 95 °C Performance 8 x less expansion than plastic bend radius half that of plastic connect Tectite tube direct to the boiler and all the way through to Tectite ended TRV’s, tap connectors and much more besides. If you have a project requiring temperature resistance, corrosion resistance or a flexible hose that can stand up to pressure or a vacuum, our stainless steel flexible metal conduit is the hose for you The vertical load at the top of the bore within the width of the excavation is the upward friction forces and the soil cohesion along the limits of the soil prism directly above the bore subtracted from the weight of the prism above the bore. The 2cCtBt in Equation 6 represents the cohesion of undisturbed soils. In his analysis of external loads on buried pipe, Marston defined two main types of loading conditions of buried pipes, a ditch conduit (referred to as trench load condition in present day nomenclature), and a projecting conduit (referred to as an embankment condition in present day literature), Table 1. Marston’s observations of load on buried pipe were validated in a 21-year study, from 1927 to 1948, where concrete, cast iron (both rigid pipes) and corrugated steel pipes (flexible pipe) were buried under an embankment of 15 ft. Measured loads on the pipes were compared with loads calculated by the Marston theory of loads on underground conduits, and were found to closely agree. Figure 4 presents measured loads on the concrete and corrugated steel pipe. It can be seen that the load on the concrete pipe was consistently 50 percent greater than that on the corrugated steel pipe of approximately the same diameter.
