ASTM D2996 – 17
This specification covers only reinforced thermosetting resin pipe RTRP. Individual reprints single or multiple copies of this standard may be obtained by contacting ASTM at the above address or at phonefaxor service astm. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.
The resins, reinforcements, colorants, fillers, and other materials, when combined as a composite structure, shall produce a pipe that shall meet the performance requirements of this specification. In the designation code, the numeral 1 shall immediately follow the HDB letter class if free-end type closures were used and the numeral 2 shall immediately follow the HDB letter class if restrained-end type closures were used asmt establish the HDB. These types, grades, classes, hydrostatic design basis categories, and cell classi?
D29966 and cleaning costs are therefore kept low and the planned pipeline is more efficient right from the outset.
ASTM D Specs – Beetle Plastics
Smooth inner walls, absolute roughness of 0. Class E—Polyester resin liner reinforced. Class I—Furan resin liner reinforced. Roughness Coefficients for Pipes Colebrook-White k 0. It can be used for different kind of environment, such as beach, benthal, river, mountain area, marshland, desert and plain etc. Long, effective service-life materials, up to 50 years. In addition, a secondary cell classification system defines the basic mechanical properties of the pipe. This strength in the wall of the pipe is equal to the circumferential stress due to internal hydrostatic pressure that will fail the pipe when extrapolated to 3 pressure cycles Procedure A or to h under continuously applied pressure Procedure B.
The American Society for Testing and Materials takes no position respecting the validity of any patent rights asserted in connection with any item mentioned in this standard. Materials shall be tested and the individual grades shall conform to the specified values of dimensions and tolerances, long-term static hydrostatic strength, long-term cyclic hydrostatic strength, short-term hydrostatic failure strength, longitudinal tensile properties, and stiffness factor.
DN15 – DN mm. According to the following international standard: All pipe ends shall be cut at right angles to the axis of the pipe and any sharp edges removed. Thermal spring delivery pipe. Current edition approved June 10, The amount of energy saved pressure pipes is an important aspect that has to be taken into account regarding the cost-effectiveness of a pipeline system.
The FRP pipe is consist of inner layer, Structural layer and outer layer. Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. The inner surface of the FRP pipe is very smooth, its friction coefficient f is 0.
This specification is applicable to RTRP where the ratio of d29966 diameter to wall thickness is If you feel that your comments have not received a fair hearing you should make your views known to e2996 ASTM Committee on Standards, at the address shown below. The Corrosion-resistant property of FRP pipe is mainly relied on the inner resin, and it can be selected based on the condition of the media.
Note 4—For the purposes of this standard, polymer does not include natural polymers. It therefore reflects practical applications under more extreme conditions as closely as possible without requiring unnecessary tests for individual criteria that can also be contradictory in the case of composites.
This technology originated in the aviation and marine industry where particularly light high-performance materials are required.

NOTE 5—All possible combinations covered by the above classi? These changes include, but are not limited to: Reinforced Ring Piping I. Not only are the hydraulic properties favorable, the smooth resin rich inner lining provides protection against highly corrosive media and the internal surface is not prone to tuberculation and encrustation.
Their molecules do not bond but they form a composite by joining their boundary layers. Recommended service design factors will not be developed or issued by Dd2996. The abbreviation for reinforced thermosetting resin pipe is RTRP. The excellent advantage for the polyurethane interlayer are cold resistant, heat insulation, light weight, big adhesive area with the outer protection pipe, uniform load transferring, good impact resistant, etc.
Lightweight, high strength and high stiffness, its density is 1. This standard does not purport to address all of the safety problems, if any, associated with its use.
