Pilewell- Sw-150 (pilling Grade - Sodium Bentonite)

We offer spilewell- sw-150 (pilling grade - sodium bentonite). Pilewell- sw-150
description- pile sw 150 is selectively mined and process for high end trenchless technology as well as trenchless drilling, it is polymer treated sodium activated bentonite which have a yield of 150 bbl. Pilewell sw-150 is highly recommended for micro tunnelling, hdd, hdb and other similar high tech trenchless process.
Why this product- aimed to achieve a good engineered water based mud for high end trenchless technology, it is very important to achieve the best rheology, require some special water based polymer. The polymer able to give perfect rheology as well as some special property like low skin friction, less heat at cutting head and thin filter cake formation.
