What is a pendent sprinkler head?

A pendent (sometimes spelled “pendant”) fire sprinkler hangs from above-ceiling pipes and distributes water in a domed or conical pattern using a convex deflector. Unlike concealed pendent sprinklers which hide behind decorative plates, the head of a traditional pendent fire sprinkler remains visible after installation.

What is the standard response sprinkler?

This refers to sprinkler heads with response time index (RTI) greater than 80 (m * s)½ and less than or equal to 350 (m * s)½.
Surface treatment of products
This product is chrome plated on the surface. The chromium plating layer has high hardness, which can vary in a wide range of 400 ~ 1200hv according to the composition of the plating solution and process conditions. The chromium plating layer has good heat resistance. When heated below 500 ℃, its luster and hardness have no obvious change. When the temperature is greater than 500 ℃, it begins to oxidize and change color, and when the temperature is greater than 700 ℃, the hardness begins to decrease. The friction coefficient of chromium coating, especially the dry friction coefficient, is the lowest among all metals. Therefore, the chromium plating layer has good wear resistance.
The chromium plating layer has good chemical stability and does not act in alkali, sulfide, nitric acid and most organic acids, but can be dissolved in hydrochloric acid (such as hydrochloric acid) and hot sulfuric acid.
In the visible light range, the reflection ability of chromium is about 65%, between silver (88%) and nickel (55%), and because chromium does not change color, it can maintain its reflection ability for a long time, which is better than silver and nickel.
