  • Facts About Insulation Requirements for Plastic Piping
    INSU L ATION Information from NAIMA: FACTS Facts About Insulation # Requirements for Plastic Piping 85 All current building energy codes and standards require pipe insulation on service hot water and HVAC piping. In this issue we discuss how much insulation is needed for domestic hot and cold service water systems and for HVAC systems in commercial and industrial buildings. While requirements vary, none of the model codes differentiates pipe insulation requirements based on pipe material. The amount of insulation needed depends on the design objectives of the system and the properties of the specific pipe material. Plastic piping for domestic hot and cold service water systems and for Common Plastic Piping HVAC systems in buildings is the Materials dominant piping material for residential construction, and is ABS (Acrylonitrile Butadiene also used routinely in commercial Styrene) and industrial applications. CPVC (Chlorinated Polyvinyl Energy codes do not differentiate Chloride insulation requirements based on PB (Polybutylene) plastic or metallic pipe wall PE (Polyethylene) material. PEX (Cross-linked Polyethylene) Plastic vs. Metal Piping PP (Polypropylene) Systems PVC (Polyvinyl Chloride) Compared to metallic piping PVDF (Polyvinylidene Fluoride) systems, plastic piping materials have a significantly lower thermal conductivity, which translates to of a given composition more or lower heat transfer between the less desirable for a given fluid and the ambient air. For application. As an example, a key some normally uninsulated piping property for hot systems is the systems, this can be advantageous. strength at temperature.

  • Hydraulics Manual Glossary G - 3
    Glossary G - 1 GLOSSARY OF HIGHWAY-RELATED DRAINAGE TERMS (Reprinted from the 1999 edition of the American Association of State Highway and Transportation Officials Model Drainage Manual) G.1 Introduction This Glossary is divided into three parts: · Introduction, · Glossary, and · References. It is not intended that all the terms in this Glossary be rigorously accurate or complete. Realistically, this is impossible. Depending on the circumstance, a particular term may have several meanings; this can never change. The primary purpose of this Glossary is to define the terms found in the Highway Drainage Guidelines and Model Drainage Manual in a manner that makes them easier to interpret and understand. A lesser purpose is to provide a compendium of terms that will be useful for both the novice as well as the more experienced hydraulics engineer. This Glossary may also help those who are unfamiliar with highway drainage design to become more understanding and appreciative of this complex science as well as facilitate communication between the highway hydraulics engineer and others. Where readily available, the source of a definition has been referenced. For clarity or format purposes, cited definitions may have some additional verbiage contained in double brackets [ ]. Conversely, three “dots” (...) are used to indicate where some parts of a cited definition were eliminated. Also, as might be expected, different sources were found to use different hyphenation and terminology practices for the same words. Insignificant changes in this regard were made to some cited references and elsewhere to gain uniformity for the terms contained in this Glossary: as an example, “groundwater” vice “ground-water” or “ground water,” and “cross section area” vice “cross-sectional area.” Cited definitions were taken primarily from two sources: W.B.

  • Applications of Centrifugally-Cast Alloy Piping and Pipe Fittings in Onshore and Offshore Oil and Gas Production
    1 Applications of centrifugally-cast alloy piping and pipe fittings in onshore and offshore oil and gas production G. L. Swales ARSM, BSc, FIM, C.Eng. is a consultant to the Nickel Development Institute European Technical Information Centre, Birmingham, England INTRODUCTION The petrochemical and oil refining divisions of major oil companies have for many years been extensive users of centrifugally-cast alloy pipe and tube mainly, though by no means exclusively, for high-temperature furnace tubes in steam hydrocarbon reforming furnaces for production of hydrogen, ammonia, methanol synthesis gas and in stream cracking furnaces for olefin production. On the contrary, the oil and gas production sectors have until the last few years made very little use of centricast pipe and tube; notable exceptions are the fairly extensive use of centricast bodies in austenitic and duplex stainless steels for barrel pumps for water injection service and centricast aluminum bronze spools for rising mains for seawater pumps on offshore platforms. However, in recent years there have been cases where centricast heavy wall alloy tubes and pipes have been used with considerable economic benefit and in some cases have substantially eased heavy wall pipe availability/delivery problems, particularly where relatively small quantities of pipe are involved. Such applications have, to date, included onshore flowlines, stainless subsea manifolds in duplex stainless steel, Christmas tree flow loops in martensitic stainless steel and topside production and test manifolds, in medium nickel alloys. An important development emanating from pipe foundries is the production of internally-clad steel pipe using centrifugal casting techniques. Production of bimetallic pipe by centricasting is itself not a new technique, formerly having been applied to high-temperature petrochemical furnace tubes to obtain the best combination of external corrosion resistance and pressure-containing capability at high temperature.

To consistently make good solvent welded joints, the following should be clearly understood and adhered to: • The joining surfaces must be softened (dissolved) and made semi-fluid. • Sufficient solvent cement must be applied to fill the gap between pipe and fitting. • Assembly of pipe and fitting must be made while the surfaces are still wet and fluid. • Joint strength develops as the solvent cement dries. In the tight part of the joint, the surfaces will tend to fuse together; in the loose part, the solvent cement will bond to both surfaces. 2. Penetration and dissolving can be achieved by the solvent cement itself, a suitable primer, or by the use of both primer and solvent cement. A suitable primer will penetrate and dissolve the plastic more quickly than solvent cement alone.

  • Plastic Pipe Terms & Definitions
    PLASTIC PIPE TERMS & DEFINITIONS Every product has certain terms and definitions that are unique to that particular product. Listed below are some of the more common terms and definitions that relate to plastic pipe. A good understanding of these definitions is essential to understanding flexible pipe and future Info Briefs and Information Series. ASTM D 883 and F 412 define additional terms relating to plastic pipe. ACRYLONITRILE-BUTADIENE-STYRENE (ABS): Plastics containing polymers or blends of polymers, or both, in which the minimum butadiene content is 6%, the minimum acrylonitrile content is 15%, the minimum styrene or substituted content, or both, is 15%, and the maximum content of all other monomers is not more than 5%; plus lubricants, stabilizers and colorants. ADDITIVE: A substance added to another substance, usually to improve properties, such as plasticizers, initiators, light stabilizers, and flame retardants. AGING: The effects on materials of exposure to an environment for an interval of time. ASH CONTENT: Proportion of the solid residue remaining after a reinforcing substance has been incinerated (charred or intensely heated). BURST STRENGTH: The internal pressure required to cause a pipe or fitting to fail. CARBON BLACK: A black pigment produced by the incomplete burning of natural gas or oil. Because it possesses useful ultraviolet protective properties, it is also much used in molding compounds intended for outside weathering applications. CELL CLASSIFICATION: A rating of the primary properties of the resin material. To include density, melt index, flexural modulus, tensile strength at yield, environmental stress crack resistance, hydrostatic design basis, color and UV stabilizer. 208 Page 1 of 5 03/96 COEXTRUSION: A process whereby two or more heated or unheated plastic material streams forced through one or more shaping orifice(s) become one continuously formed piece.
