The line pipe specification shall consider the following The corrosion coating materials include FBE, 3LPE and 3LPP. The anti-abrasion coatings are HDPE and HDPP. The thermal insulation coatings include GSPU, multi-layer PP and PUF.Riser Pipe - an overview ScienceDirect Topics

### What is a riser section?What is a riser section?The main riser sections are of pipe-in-pipe type construction with the outer pipe acting as a conductor. At the base of the riser, there is a stress joint (there may also be a similar section near the point of exit at the base of the hullreferred to as the keel). The annulus between the riser and the outer pipe is usually flooded with seawater.Riser Pipe - an overview ScienceDirect Topics What is piping stress analysis?What is piping stress analysis?The most of widely used piping stress analysis software, including START-PROF, apply fluid weight as uniform load along the pipe. This approach is correct for horizontal piping and short vertical pipes. But it is incorrect for tall risers and may lead to incorrect support loads and incorrect stress distribution along the vertical pipe length.Stress Analysis Features of the Tall Pipe Risers What Is Stress Analysis Features of the Tall Pipe Risers What Is 3 Sprinkler Riser Types DoItYourself

Swing joint risers allow sprinklers to move slightly. Mostly professional plumbers use this type of riser. Because the riser allows the sprinkler head to move slightly, it prevents any incidences of breakage caused by stress. It also allows easier adjustment to the location of the sprinkler head.

Internal or external pressure induces stresses in the axial as well as circumferential (Hoop Stress) directions.6. STRESS CONCENTRATION AND STRESS RAISERSThe stress-strain relation is linear, elastic (to yielding) for metal and is nonlinear, elastic for rubber. This difference is offset by the large, easily measured strains, which occur in rubber. Usually a square grid of lines is printed on the surface of the specimen.Author Linda DingleyPublish Year 2010Engineering Design of Pipe Supports - SlideShareOct 06, 2011This presentation will cover pipe support design, 3D modeling, Finite Element Analysis, special stress and thermal cases, along with the unique cases that brought on new pipe support designs.

Transportation of liquids by pipelines has been used for thousands of years. The first major exploitation and commercialization using pipelines started 150 years ago, and the building of long distance, large diameter pipelines was pioneered in the 1940s (Hopkins, 2007).Todays pipeline industry has originated from the oil business that brought considerable amount of profit to the energy Stress Analysis Features of the Tall Pipe Risers What Is Piping Stress Analysis Page 22 What Is Piping All Stress Analysis Features of the Tall Pipe Risers What Is Stress Analysis Features of the Tall Pipe Risers Tall pipe risers are used in skyscrapers, mines, etc. There are two points that the piping stress engineer should consider:Fluid weight load distributionPipe longitudinal stabilityFluid Stress Analysis Features of the Tall Pipe Risers What Is Piping inlet for vertical tanks - Storage tank engineering Stress Analysis Features of the Tall Pipe Risers What Is There will be very low stresses on the tank shell and most can be totally avoided if you put a pipe support under the riser. If you can't put a pipe support there, add diagonal braces to support the pipe and take loading off the nozzles. If your pipe stress program shows high axial loads, add an expansion joint just before the riser.
