* Suggested Fire Protection Specification:
Welding branch outlet fittings employing cut or roll grove, male thread or buttweld bevel shall be U.L./U.L.C. listed and F.M approved conforming to NFPA, Bulletin 13 of Domestic Manufacture as produced by Island Fitting Company, Memphis, TN 38108

Highly weldable grade black carbon steel pipe equal to or exceeding the requirements of the American Society for Testing and Materials specifications) our option of the following in single/dual or triple stenciled material: A-135, A-795, A-53. (ERW, CW, or BW)

Figures 40CG / 40RG / 40MT / 40BW up to 500 CWP in PSI
Figure 10RG up to 300 CWP in PSI

*Pressures have been established using listed and/or approved couplings and fittings of equal or higher ratings, Hydrostatic test of 2:1 for maximum working pressure and 5:1 for strength of body (4:1 for 8″).

Dimensional integrity is assured with accurate machining, stringent quality control procedures, and sound fabrication techniques. Grooves, threads and bevels are constantly checked for proper alignment and concentricity, uniform depth, taper and degree, as applicable, conforming to established industry standards.

For Identification, each fitting bears the name “ISLAND”, or registered trademark, along with appropriate figure number and end preparation designation. In addition, the nominal outlet and header size in inches, and CULUS, FM, indicating listing and approval with recognized testing laboratories.

ISLAND weld outlets are designed to provide unobstructed full flow. This is accomplished by making the inside diameter of the low weld volume machine contour precisely fit the outside diameter of the adjoining pipe/ header to be welded. The full penetration weld is made forming a smooth passageway to prevent catching or clogging of foreign matter. Therefore, no special allowances are necessary when utilizing computer hydraulic flow calculations.

ISLAND type 40 & 10 weld outlets are manufactured in a wide range of header sizes. Each fitting is manufactured “size on size”. This means the outlet fits exactly on the header to which it is welded, so it is ideal for use with automatic welding machines.

FINISH: Fittings are cleaned to bare metal internally and externally and protected with a smokeless rust inhibitor giving a lasting finish to extend shelf life.

For convenience in warehouse handling, storage, and inventory control, ISLAND Figure 40 and 10 fittings are packaged in corrugated cartons; palletized and sealed with shrink wrap plastic. Thread protectors are provided with #40MT to insure quality from factory to job site.

In addition to brochure listings; black carbon seamless, stainless steel and other materials, sizes up to 36″ O.D.; various wall thickness, lengths , shapes, degree of intersection and end preparations are available and can be supplied on special order. Please call for additional information.

ISLAND type 40 and 10 outlets are listed and approved to be used with every manufacturers’ brand of sprinkler pipe. This includes schedules 5, 7, 10, 20, 30, 40 and any other proprietary sprinkler pipe being manufactured. In other words, ISLAND outlets, whether type 40 or type 10 can be welded to any schedule steel pipe available, without limitation to the fitting.

Welding branch outlet fittings employing cut or roll groove, male thread or buttweld bevel shall be U.L./U.L.C. listed and F.M. approved conforming to NFPA, Bulletin 13, of Domestic Manufacture as produced by ISLAND FITTING COMPANY, Memphis, TN 38018

Good piping practices should always prevail. The designer should always take into consideration the design data of other manufacturers’ products when used in conjunction with ISLAND fittings, as well as environmental and service factors such as temperature, specific pressures, and external or internal loads.
