If the surface...

... the sample bursts. Since the test specimens included pipe jointed to the ends of fittings, the same test spools were also used to qualify the pipe-to-fitting joints per ASME B31.1 and B31.3. For pipe-to-fitting joints, ASME B31.1 required the qualification joint to be pressure tested at 1.5 times...

...Abstract It is difficult to find CUI of pipe in chemical plants because the arrangement of pipes in chemical plants is too complex and the susceptible areas for CUI are too large. So, for the purpose of effective management of CUI of pipes, an effort has been made to locate CUI by using operation...

...The Pipe System The composite pipe system, known as X200 ⁽¹⁾ , is a steel strip laminate technology which uses high-performance adhesives to manufacture a metallic composite pipe. It offers a new method of low cost pipeline construction suitable for onshore gas and oil pipelines...

They understand that at times...

...Abstract Testing using miniature pipe specimens called mini-pipes has been introduced previously as a means to evaluate casing materials loaded with three-dimensional, pressure-induced stresses and one-sided or two-sided H₂S exposure.^1-3 Hollow mini-pipe specimens are able...

.... Fabrication of coarse grain pipe and plate for chemical processing vessels and systems has resulted in cracking of the formed components during heat treatment after forming. Samples cut from the cracked areas of the formed sections revealed the microstructure of the cracks to be as seen in Figure 2...

... a flammable liquid flowing into a FRP tank or through a FRP pipe may develop a static charge on the wall of the tank. This report describes how to make FRP equipment electrically conductive to prevent the buildup of a static charge and thus avert a potentially dangerous situation. fiberglass reinforced...

Pipe FBE PE DPS External coating gouge resistance Property evaluation The gouge properties can be different for the same type of coating which were supplied by different material manufactures. By comparing the test results from different coating...

...When the brine is at its minimum temperature, metallic parts in contact with the brine actually develop a thick layer of ice. Although the FRP piping will sweat some, no frost or ice is formed because of the thermal insulating properties of FRP laminates. Of course, when the brine temperature...

...INTRODUCTION Abstract This paper is a greater than 30 year case history on the use of fiberglass reinforced plastics (FRP) at three power plants. The first project was a 16.3 foot (5 meter) diameter pipe installed in Florida, constructed with a resilient isophthalic polyester resin and used...

...FRP Fiberglass pipe HCl adhesive joints butt wrap INTRODUCTION Hydrochloric acid is a versatile processing chemical used extensively in mining, pulp & paper, and many other industries. The corrosive nature that makes HCl so effective also makes it very difficult to handle, process...

...Abstract In multiphase flow, bubbles are produced and collapse on the solid/liquid interface. Bubble collapse can enhance the CO₂ corrosion of carbon steel pipe, as shown by coupon surface analysis, corrosion rate measurements and visualization of bubble movement in multiphase flow...

Both users and manufacturers of Oil Country Tubular Goods could benefit from a reexamination of the basis for such test requirements. Sulfide Cracking Testing Statistics Quality oil country tubular goods pipe...

... is a simplified explanation of the process for a vinylester resin. Abstract This paper will look at the effect of postcuring on the performance of filament wound, vinylester piping. Information will be presented on the changes in both chemical resistance and physical properties effected through postcuring...

...For criticai expensive pipe or fabrications, one option is to ship the items containerized, and supply dry air using a dehumidifier. In storage at the factory or at the receiving warehouse, a similar system can be installed. In large, uncontrolled storage areas, simple, inexpensive tension fabric...
