Heat treatment of petrofer oil quenching harderning in the tempering process is used to increase the hardness value of S45C steel. PT Instatama conducts heat treatment of petrofer oil harderning quenching in order to produce high quality bolts. Heat treatment process on a large scale carried out at PT. Insastama, there are problems, namely the difference between the inner hardness value and the…
Superheater is one of the components of a boiler that has a crucial function, superheater functions to produce superheated steam which is used to drive turbines. Water vapor flowing into the superheater pipe will have a heat transfer in the pipe. The water vapor in the superheater pipe is not always clean, therefore there is often a sediment inside the superheater pipe. The longer the deposits …
In the construction planning of a building at the present time, has experienced quite rapid development, there are several types of building structures that are used, including steel structures, reinforced concrete structures and precast concrete structures. These three elements differ in terms of the nature of the material aspects, methods of implementation that affect the time of implementati…
This research was conducted to determine the flexural tensile strength of the connection angles old concrete and new concrete with adhesive and fiber reinforcement. The test specimen used is cylindrical for normal concrete (150 mm in diameter and height) 300 mm), and beam test specimens (size 150 mm x 150 mm x 600 mm). Quality of concrete ones planned 25 Mpa. This test uses 36 specimens with an…
The purpose of this Final Project is to solve the problem of the delay in the implementation of the New 12 Floors Building Project Phase I of the Administration Faculty, Universitas Brawijaya Malang by determining the types of work that can be accelerated, determining the number and types of labor, and handling costs for acceleration. It also can set the planned implementation time precisely. …
