Can the Reducing socket connector, stainless steel, M767LM be used with different tube wall thicknesses and how is permissible working pressure determined?

Yes. The Reducing socket connector, stainless steel, M767LM can be used with tubes of different wall thicknesses, because its permissible working pressure is determined according to the tube outer diameter and wall thickness. One side of the connector requires only a nut (sealing on the cone, no rings), the other side requires a complete set (nut plus rings). To select the correct working pressure and ensure safe use, consult the pressure values given for the specific tube outer diameter and wall thickness (see the attachment/data sheet). Material: AISI 316 stainless steel.

Does the Reducing socket connector, stainless steel, M767LM require different nut/ring arrangements for each connection side?

Yes. The Reducing socket connector, stainless steel, M767LM requires different nut/ring arrangements on each side: one side needs only a nut (no rings; sealing on the cone), while the other side requires a complete set-a nut plus rings. Working pressure depends on tube outer diameter and wall thickness. Material: AISI 316 steel.

How is the permissible working pressure for the Reducing socket connector, stainless steel, M767LM calculated from tube OD and wall thickness?

The permissible working pressure for the Reducing socket connector, stainless steel, M767LM is determined from the tube outer diameter (OD) and wall thickness using the allowable internal pressure formula for cylindrical pressure vessels (thin- or thickâwalled tube assumptions as appropriate) and the material allowable stress for AISI 316. In practice the calculation follows these steps: 1. Identify tube dimensions: outer diameter (OD) and wall thickness (t). Compute the mean (inner) radius: r = (OD/2) - t. 2. Determine whether thinâwall assumption applies: if OD/t â¥ 20, use thinâwall hoop stress formula; otherwise use thickâwall (Lame) formula. 3. Thinâwall hoop stress (Ïh): Ïh = (p Â· r) / t, solved for p gives permissible p = (Ïallow Â· t) / r. - Ïallow is the allowable design stress for AISI 316 (use the value from applicable code/standard or manufacturer data, including safety factor and temperature corrections). 4. Thickâwall (Lame) radial/hoop stress: for internal pressure p, maximum hoop stress at inner radius is Ïmax = p Â· (ri^2 + ro^2) / (ro^2 - ri^2), where ro = OD/2, ri = ro - t. Solve for p: permissible p = Ïallow Â· (ro^2 - ri^2) / (ri^2 + ro^2). 5. Apply joint/fitting factors: account for connector geometry (reducing socket), sealing on cone, and assembly requirements. Apply any additional reduction factors from the attachment or manufacturer (e.g., thread stress concentration, temperature, corrosion allowance, and safety factors). The manufacturerâs attachment contains tabulated permissible pressures for common OD/t combinationsâuse those tables if available. 6. Final check: ensure calculated permissible pressure does not exceed published values in the attachment and complies with applicable standards (e.g., EN, ASME) and the connectorâs rated pressure. In short: compute allowable internal pressure from OD and t using thinâ or thickâwall formulas with AISI 316 allowable stress, then apply manufacturer/assembly reduction factors or use the attachmentâs tabulated permissible pressures for the Reducing socket connector, stainless steel, M767LM.

Additional information

Material	SS – stainless steel

The reducing connector allows the connection of two fittings or a fitting with an adapter. A nut is required on one side, without rings (sealing occurs on the cone), while on the other side a complete set is required – a nut and rings. The permissible working pressure is determined based on the outer diameter and wall thickness of the tube (details in the attachment). Material: AISI 316 steel.
