2.7 Cutting and Debumng
Pipe shall be field-cut with a combination factory tool that results in a cut that is square, clean, and free of burrs. An approved manufacturer’s cutting fluid shall be used during the cutting and beveling process. The manufacturer’s cutting fluid shall be wiped off so that it shall not come in contact with the 0-ring (internal sealing ring). The installer shall follow the manufacturer’s installation recommendations.
Pipe shall be plain-end, single-socket, or doublesocket. Pipe fittings shall have one socket for each inlet or branch connection designed to join directly to the spigot end of a pipe or pipe fitting made to this Standard. An accessory fitting such as a floor flanges. trench drains, cleanouts, and plugs shall have only one spigot for connection to a socket or spigot.
2.9 Adapters for Transition to Other Piping MateriaLs Joints between dissimilar piping materials shall he
made using applicable mechanical joint couplings that meet their applicable materials standard for that material.
2.10 Drain Requirements
Drain outlet dimensions shall comply with the dimensional requirements in Table I.
2.11 Outlets Types and Connections
2.11.1 Outlet Types. Drains shall be manufactured with a horizontal or vertical outlet.
2.11.2 Outlet Connections. Connections shall be of the spigot. optional threaded, or caulk type.
2.12 Drain Top Configuration
The open area of the drain top shall be at the option of the manufacturer provided it meets the open area requirements of Table 48.
2.13 Grate Openings
The openings in the grate shall be any geometric
shape. The open area shall be in accordance with Table 48
2.14 VariatIons In Drains
The optional features listed are stated to identify the variations .wailahlc for different applications. Variations shall be included, but not limited to
(b.i anchor flanges
(c) backwater valves
(d) auxiliary inlets
(t) clamping devices
(I) special grates
(It) secondary strainers
(1) sediment buckets
(j) trap primer conflectlons
(k) removable trap seaLs
Components made of other materials shall be in accordance with their applicable product standards, codes, or listing (where available), and the joint shall be in accordance with the requirements of this Standard.
The joints shall be of a smooth and clean surface. Surfaces shall not have any defects or irregularities. which could affect the functioning or which would interfete with normal joining of the product.
2.17 Internal Sealing Ring (ORing)
Different sealing ring materials shall be permitted to accommodate various applications in accordance with the manufacturer’s instructions. Material shall be marked or color-coded by the manufacturer as acceptable to identify.
2.18 Other Gravity and Vacuum flttings
Custom-fabricated fittings, to transport sanitary waste and various other fluids and effluents, shall meet the dimensional requirements of this Standard when required.
2.19 Other Floor Drain Dimensions
Floor drain dimensions shall comply with lables 39 through 44.
2.20 Cteanout Fitting
Stainless steel, gas-tight covers shall comply with Table 45.
2.21 Stainless Steel. Floor Drain Water Trap
Stainless steel, floor drain water traps shall comply with Table 46.
2.22 Other Trench Drain Dimensions
Trench drain dimensions shall comply with Table 47.
3 TEST METHODS AND PERFORMANCE REQUIREMENTS
3.1 Tensile Strength
Mill certificates shall be furnished upon request to vtiiy tensile strength in compliance with the minimum requirements. The pipe and fittings for Type 304 stainless steel shall have a minimum tensile strength of 5(X) MPa (73,000 psi). The pipe and fittings for Type 3161. stainless steel shall have a minimum teniIe strength of 485 MPa (71,000 psi).
3.2 Hardness Pipe and Fittings
32.1 Type 304. The Brinell Hardness for Type 304 stainless steel shall be between 130 and 180.
3.2.2 Type 316L. The Brinell Hardness for Type 3161. stainless steel shall be between 120 and 180.
3.3 Water Tightness of Welds and Pipe joints
3.3.1 All pipe fittings and ,oints shall be watertight from 0 kl’a to 50 kl’a (0 psi to 7.25 psi). Testing shall be performed in accordance with para. 3.4.1.
3.32 For use in areas subject to elevated pressure (eg., lift stations and rainwater leaders subject to backups) the manufacturer shall establish maximum pressure rating according to the test described in para. 3.4.2.
3.4 Weld and Joint Test
3.4.1 Test Method. A representative assembly of the fittings being listed that includes the pipe and joints shall be restrained per the manufacturer’s final installation guidelines at ambient temperature under hydrostatic pressure 50 kPa (7.25 psi) for 20 mm. There shall be no leaks.
