BSPF = British Standard Pipe Fitting is an obsolete designation

BSPF = British Standard Pipe Fitting is an obsolete designation which has been replaced with the G-Series per ISO 228

BSPF was the thread marking per screw thread designation BS-2779. BS-2779 has been rescinded and should no longer be used. The new screw thread designation is specifies a G in front of the nominal diameter and is defined in ISO-228.

In March 2003, the British Standards Institute withdrew BS-2779 and replaced it with ISO-228 (technically BS-EN-ISO-228)

Example: G1/2 x 14 BSPP Go Thread Ring Gage - Class A

Class A is considered the standard tolerance. Class B is a loose tolerance twice the amount of Class A. Class B only refers to the No Go Thread Ring Gage

There are many drawings that call out British Standard Pipe (BSP) to refer the current G-series screw thread. It should always be confirmed as BSP may also be a shortened version of BSPT -British Standard Pipe Taper.

Thread Check Goes Solar

Thread Check Inc. located on Long Island New York is now using solar power to handle up to 80% of its electricity consumption at its New York facility. The solar power system was designed and installed by GreenLogic Energy of Southampton NY. The system is designed to handle 47.775 K utilizing 195, 245 Watt Canadian Solar, panels.

The electricity is produced from sunlight using what are known as photovoltaic cells. These cells are built into thin glass-like panels of silicon material that have been mounted on top of Thread Check’s facility. The panels produce electricity when exposed to sunlight. Solar Panel systems are extremely reliable with no moving parts and typically last 30+ years with no maintenance.

The electricity produced by the solar panels produce can either be directly used in their offices and factory or sent back to the utility company for credit. To accomplish this, the power coming off the panels goes through a device called an inverter. The inverter monitors the solar power system, conditions the power, and keeps track of how much electricity is produced and then feeds the power to the appropriate place.

The system incorporates a web portal that monitors the energy and efficiency of the system in real time.

The life time carbon reduction is 3,030,509 Lbs. of Co2.

It is the equivalent of planting 19 Acres of trees.
