2.Flange

There are many different flange standards to be found worldwide. To allow easy functionality and

interchangeability, these are designed to have standardised dimensions. Common world standards

include ASA/ASME (USA), PN/DIN (European), BS10 (British/Australian), and JIS/KS (Japanese

/Korean). In the USA, ANSI stopped publishing B16.5 in 1996, and the standard is ASME B16.5.

In most cases these are interchangeable as most local standards have been aligned to ISO

standards, however, some local standards still differ (e.g. an ASME flange will not mate against

an ISO flange). Further, many of the flanges in each standard are divided into "pressure classes",

allowing flanges to be capable of taking different pressure ratings. Again these are not generally

interchangeable (e.g. an ASME 150 will not mate with an ASME 300).

These pressure classes also have differing pressure and temperature ratings for different materials.

Unique pressure classes for piping can also be developed for a process plant or power generating

station; these may be specific to the corporation, engineering procurement and construction (EPC)

contractor, or the process plant owner. The ASME pressure classes for Flat-Face flanges are

Class 125 and Class 250. The classes for Ring-Joint, Tongue & Groove, and Raised-Face flanges

are Class 150, Class 300, (Class 400 - unusual), Class 600, Class 900, Class 1500, and Class 2500.

The flange faces are also made to standardized dimensions and are typically "flat face", "raised

face", "tongue and groove", or "ring joint" styles, although other obscure styles are possible.

Flange designs are available as "weld neck", "slip-on", "lap joint", "socket weld", "threaded", and

also "blind".

3.ASTM B 16.5

The B16.5 Standard defines the following:

(1) Dimensions

(2) Tolerances

(3) Materials

(4) Markings

(5) Pressure/Temperature Ratings

(6) Pressure Testing

6.Polishing

Polishing is the process of creating a smooth and shiny surface by rubbing it or using a chemical

action, leaving a surface with a significant specular reflection (still limited by the index of

refraction of the material according to the Fresnel equations.In some materials (such as metals,

glasses, black or transparent stones), polishing is also able to reduce diffuse reflection to minimal

values. When an unpolished surface is magnified thousands of times, it usually looks like

mountains and valleys. By repeated abrasion, those "mountains" are worn down until they

are flat or just small "hills." The process of polishing with abrasives starts with coarse ones and

graduates to fine ones.

7.ASME standards (U.S.)

Pipe flanges that are made to standards called out by ASME B16.5 or ASME B16.47, and MSS SP-44.

They are typically made from forged materials and have machined surfaces. ASME B16.5 refers to

nominal pipe sizes (NPS) from ½" to 24". B16.47 covers NPSs from 26" to 60". Each specification

further delineates flanges into pressure classes: 150, 300, 400, 600, 900, 1500 and 2500 for B16.5,

and B16.47 delineates its flanges into pressure classes 75, 150, 300, 400, 600, 900. However these

classes do not correspond to maximum pressures in psi. Instead, the maximum pressure depends on

the material of the flange and the temperature. For example, the maximum pressure for a Class 150

flange is 285 psi, and for a Class 300 Flange it is 740 psi (both are for ASTM A105 Carbon Steel and

temperatures below 100F).

The gasket type and bolt type are generally specified by the standard(s); however, sometimes the

standards refer to the ASME Boiler and Pressure Vessel Code (B&PVC) for details (see ASME Code

Section VIII Division 1 – Appendix 2). These flanges are recognized by ASME Pipe Codes such as

ASME B31.1 Power Piping, and ASME B31.3 Process Piping.

Materials for flanges are usually under ASME designation: SA-105 (Specification for Carbon Steel

Forgings for Piping Applications), SA-266 (Specification for Carbon Steel Forgings for Pressure Vessel

Components), or SA-182 (Specification for Forged or Rolled Alloy-Steel Pipe Flanges, Forged Fittings,

and Valves and Parts for High-Temperature Service). In addition, there are many "industry standard"

flanges that in some circumstance may be used on ASME work.

The product range includes SORF, SOFF, BLRF, BLFF, WNRF (XS, XXS, STD & Schedule 20, 40, 80),

WNFF (XS, XXS, STD & Schedule 20, 40, 80), SWRF (XS & STD), SWFF (XS & STD), Threaded RF,

Threaded FF & LJ, with sizes from 1/2" to 16". The bolting material used for flange connection is stud

bolts mated with two nut (washer when required). In Petrochemical industries, ASTM A193 B7 STUD

& ASTM A193 B16 Stud Bolts are used as these have high tensile strength.
