Fire Sprinkler Pipe WLS & WST

API NSF ISO
 

WLS-SCHEDULE 30

Wheatland Lightwall Sprinkler Pipe (WLS) is threadable,lightwall, ASTM A 795F steel pipe used for sprinkler applications. WLS is a standard nominal outside diameter pipe product and conforms to the Schedule 30 dimensions set forth in ANSI/ASTM B36.10M-1995.

Wheatland has engineered over 60 years of experience and quality control into its sprinkler pipe products. WLS has the service life and application range needed to provide a quality sprinkler system installation.

WLS is approved for use with threaded, welded, roll grooved or plain end fittings. WLS complies with the appropriate ASTM, ANSI, NFPA Standard and is UL Listed and FM approved. When hot dip galvanized, WLS is FM approved for use in dry systems. Wheatland's product quality is assured by hydrostatic tests to 1200 psi and non-destructive Eddy (NDE) current tests.

† Can be threaded or roll grooved to order.

WST-SCHEDULE 5

WST is UL Listed, FM approved, and conforms to ASTM A 795E and ASTM A 135. WST can be joined using Victaulic's PRESSFIT™ fittings or welded fittings. This lightwall Schedule 5 pipe from Wheatland exceeds the standards set by UL and FM. Based on the CRR values, the life expectancy of Wheatland's WST pipe is equivalent to or greater than the threaded portion of Schedule 40 pipe.

WST has a galvanized O.D. It provides a dry surface and gives a better appearance, matching the PRESSFIT ™ fittings. WST's larger I.D. normally yields better hydraulics and can often lead to down-sizing of piping required.

*CRR Ratio - Corrosion Resistance Ratio compared to Sch. 40.
Schedule 40 threaded pipe is used as the benchmark (value of 1.0).
The CRR values of WST are higher than any threaded sprinkler pipe (except 2").
