Flange joint

Le flange lap- joint, con normativa di riferimento ASME B16. ASTM A1Aisi 304L EN 1. A flange joint is a non-permanent, removable method of joining or blanking off steel and plastic pipes. When two pipes are to be joine the two discs are placed against each other in such a way that the holes line up.

The following item has PN marking with reference to the nominal pressure. The key types of flanges are the welding neck, long welding neck, slip-on, socket wel lap joint, threaded and blind flanges.

CEKPI KOGPUKQPU ANSI B 16. A ring joint flange features a circular groove to accommodate a ring joint gasket (oval, or rectangular). There are two methods to connect the flange : one is the threaded joint flange and the other is the welded flange.

Sign in to download full-size image Fig. Pressure rating of the flange determines the height of the raised face. Diameter and height are in ASME B16. Lap joint pipe flanges slide directly over the pipe and are most commonly used with stub end fittings.

A pipe is usually welded to the Stub End and the Lap Joint pipe flange is free to rotate around the stub end. The benefit of this is that there will not be any issues with bolt hole alignment. A flanged joint is composed of separate and independent, although interrelated components: the flanges, gasket, and bolting, which are assembled by another influence, the assembler.

Proper controls must be exercised in the selection and application for all these elements to attain a joint that has acceptable leak tightness. FLANGE LAP JOINT FORGIATE.

STAINLESS STEEL AND CARBON STEEL. Vengono utilizzati su apposite flange. Pipe Size Pitch Diam. The stub-end straight adapter slides into the flange and welds to pipe (not the flange ). Learn about the key flange gaskets types (used in the oil and gas industry): non-asbestos gaskets full and raised face (used for low-pressure, low-temperature and non-critical applications), spiral wound gaskets (for higher temperature and pressure oil and gas applications), Ring joint gaskets style R, RX, BX (for RTJ flange faces), Kammprofile and Jacketed gaskets.

The edge (periphery) of each ring joint flange shall be marked with the letter R and the corresponding ring groove number. Notes: (1) The height of the raised portion is equal to the depth of the groove dimension, E, but is not subjected to the tolerances for E. Former full-face contour may be used.

Flange Long Welding Neck. Busca Más Rápido y Mejor en ZapMeta Ya! Questa flangia viene utilizzato con i lap joint stub end fitting.

Il raggio e la flat face, entrambi consentono alla flangia di fissare contro il raccordo stub end. What is a ring type joint flange ? The flanges seal when the bolts are tightened and the gasket is compressed into the groove making a metal to metal seal.

An RTJ flange usually has a raised face with the groove machined into the face of the flange. To fully support our customers requirements, Teconnex offers two options: - Complete design, development, and volume manufacture of the joint assebmly. RTJ flanges refers to pipe flanges manufactured in accordance with ASME B16. Di seguito una selezione di flange disponibili nel catalogo Tecnoindustria Piping, realizzate con una vasta gamma di acciai al.

Lap joint flange (simplified as LTF flange ) shape is similar to slip on flange, it has a curved radius at the bore, which can connect with a stub end fittings and slide over the pipe. In this form, the pipe is usually welded to this stub end so the lap joint flange can rotate freely around the stub end.

With flange Face the form and implementation of the side of a flens are meant, where a sealing ring or gasket will be placed. Ring Type Joint (RTJ) - Typically found on the most severe duties, for example high pressure gas pipework. Ring type metal gaskets must be used.

A flange face (raised face and flat face) has a specific roughness to ensure that this surface be compatible with the gasket and provide a high quality seal as under compression.
