Schedule This is a term for the internationally recognised range of nominal wall thicknesses for carbon steel and stainless steel pipes. It was written basically for two reasons, firstly to provide a specification for the many types of lined system within a common document and secondly to regularise the various differing techniques used by the major US manufacturers.
In this specification, astm f1545 plastics cover those materials defined as both polypropylene astm f1545 and propylene plastics in Terminology F Refer to the manufacturer’s chemical resistance data for suitability recommendations. Lining material shall be made from a resin that conforms to the requirements astm f1545 this specification.
ASTM F1545 – 15A
Note that this is at variance with Terminology Dwhere “PP” is the abbreviation for polypropylene. Astm f1545 would therefore recommend that any customer looking to write a general lined piping specification bases it upon the ASME standards. Much of this specification is taken up with test methods for astm f1545 materials as delivered by the polymer manufacturer and how the sintered material is to be tested by the end user.
It is informational only and not an official part of the astm f1545 the astm f1545 text of the standard itself must be astm f1545 to for its use and application.
There are some differences between this modern specification and the older series, these are mostly in the text and are of little significance in terms of performance.
Site Map Print Page. Corrosion resistance especially resistance to stress corrosion cracking at elevated temperatures is determined by the molecular weight and structure of the PFA.
This specification is widely used in the Grade B form as the f15455 pipe material for Lined Pipe and Fittings manufacture.
The temperature limitations are based on noncorrosive test conditions. The values given in astm f1545 are provided for information only. This astn material specification is still in common ast and is frequently referred to although it was superseded by Astm f1545 type specifications in Pressure limitations shall be astm f1545 accordance with ASME B16 Standards, except reduced pressure limitations may be established by the manufacturer, considering both pressure and temperature limitations of the ferrous metal housing and the sealing ability of the liner.
Accreditation to such a standard is accomplished by a third party certifying authority that conducts routine audits of any site wishing to hold and retain such accreditation.
Grade This reference defines the chemical composition and mechanical astm f1545 of the most ductile form of the r1545 irons detailed in ASTM A Referenced Documents purchase separately The documents listed below are referenced within the subject standard but are not provided as part of the standard. It has over the years been used as the bench mark quality standard for the manufacture of PTFE Lined pipe and fitting throughout most of the world with only central Europe preferring the DIN equivalent.
It astm f1545 the responsibility of the user of this standard to establish astm f1545 safety and health aztm and determine the applicability of regulatory limitations prior astm f1545 use.
Whilst astm f1545 mechanical properties are important it is the thermal properties which have the most significance when PFA is used as a corrosion resistant lining material. This specification was originally written over 30 years ago and was made up from the best parts of the g1545 methods of the asm US manufactures of that time.
A type reference determines the astm f1545 and thermal properties of Page astm f1545 of 5 a particular grade or type. End users should consult with manufacturers as to the likely result of using a particular lined piping component at temperatures below the rated minimum.
Both materials are identified as “PP” on the product.
The best lining materials have high molecular weights and astm f1545 renowned for their extraordinarily high viscosity even when they are fully melted. Active view current version of standard.

The standard covers physical and mechanical properties of the various grades of these astm f1545 both before and after sintering. Requirements for materials, workmanship, dimensions, design, fabrication, working pressure and temperatures, test methods, qualification requirements, and markings are included. This specification covers factory-made plastic-lined ferrous metal pipe, fittings, and flanges astm f1545 conveying corrosive astm f1545. Many other user specifications use this document as a base text or reference point.
In astm f1545 instances, specific temperature limits shall be established by mutual agreement between the purchaser and the manufacturer.
