STANDARD PRACTICE. SP i. This MSS Standard Practice was developed under the consensus of the MSS Technical Committee and. edition of MSS-SP Standard-. "Integrally Reinforced Forged Branch. Outlet Fittings." FLEXOLETT reduces the number of fitting. Excellence in Quality is the standard . Design per MSS-SP Standard Weight Fittings are the same as schedule 40 fittings through 10".

The existence of an MSS Standard Practice does not in itself preclude the manufacture, sale, or use of products not conforming to the Standard Practice. Mandatory conformance to this Standard Practice is established only by reference in other documents such as a code, specification, sales contract, or public law, as applicable.

This Standard Practice has been substantially revised from the previous edition.

It is suggested that if the user is interested in knowing what changes have been made, that direct page by page comparison should be made of this document. Non-toleranced dimensions in the Standard Practice are nominal, and, unless otherwise specified, shall be considered "for reference only".

Combining values from the two systems may result in non-conformance with the Standard Practice. The values stated in each option are not exact equivalents; therefore, each measurement system must be used independently of the other.

Within these limits, the maximum allowable pressure of a fitting shall be that computed for straight seamless run pipe of equivalent material as shown by comparison of composition and mechanical properties in the respective material specifications. The pipe wall thickness corresponding to each Class of fitting, for rating purposes only, is shown in Table 1.

See Figure 1. Alternatively, the designation 3M or 6M, as applicable, may be used where "M" stands for 1, The branch connection must reinforce the opening and restore the original strength of the run pipe.

It is the intent of this Standard Practice that these integrally reinforced branch outlet fittings and the deposited weld metal used to attach the fittings to run pipes contain all the reinforcement required by the applicable pressure vessel or piping codes without the addition of saddles or pads.

ASME B The ends are bevelled to facilitate this process, and therefore the weldolet is considered a butt-weld fitting.

Weldolet's are designed to minimize stress concentrations and provide integral reinforcement. The bore matches the outlet bore, and the existence of a counter bore roughly the size of the OD of the outlet provides a socket where the pipe can sit, facilitating installation and welding. The bore matches the outlet bore, and the existence of this threading facilitates installation, as no welding is necessary. Available butt-weld to meet specific reinforcement requirements, and and classes for Socket Weld and threaded applications.

Available with male-socket weld or male threaded outlets. The attachment weld is easily examined by radiography, ultrasound and other standard non-destructive techniques. Manufactured to meet your specific reinforcement requirements. Available with socket or threaded connections. G enerally the schedules of the run pipe and branch pipe are identical and thus specification of the equivalent schedule Weldolet assures the proper fitting being used.

Designs for thicknesses greater than these can be developed on request.

Make sure that the supplier has a design approval for the fitting there are many small outfits out there making their own fittings without any documentation.
