Overall Performance Evaluation of Tubular Scraper
Evaluating tubular scraper conveyors using the TOPSIS method assists in reducing the influence of design and subjective factors during conveyor use and in selecting the optimal solution. Therefore, TOPSIS may serve as a suitable method for the overall performance evaluation of tubular scraper conveyors.
Tubular & Bearing Pile Solutions | Ivor King
Piles may be top driven to ‘set’ or length using purpose-built rigs with hydraulic hammers. The internal void can subsequently be filled with concrete or grout if required, with reinforcement incorporated for bonding into pile cap or ground beams. Normally the tubular piles are driven open ended so that a soil plug is rapidly formed.

The optimum viscosity may be as high as 95 cSt for low-speed, heavily loaded or shock-loaded journal bearings. Using this method requires some knowledge of the oil temperature within the bearing under operating conditions, which can be difficult to determine. Fortunately, an accurate oil temperature is not needed for most viscosity determinations.

Tubular Cast-On Tutorial – The Bluprint Blog | Craftsy
Nov 12, 2015· Tubular cast-on tutorial: 2×2 rib. Casting on for 2×2 is very similar to casting on for 1×1 rib. In fact, you will create the foundation rows in exactly the same way. However, you don’t have to worry about ending up with the wrong ribbing. We are going to work some knitting magic on the last foundation row, making the 1×1 rib into 2×2.
