How good is Playing with Graphs by Amit M Aggarwal
It is a very helpful book for JEE Advanced, I myself used this for my JEE preparation. Before buying this book I was very much afraid of the graphs and my teacher also used to tell us innovative approaches to solve conventional problems easily using graphs it made me more anxious, I thought ‘if this scenario continues I will surely loose my grip from mathematics(especially calculus)’ . Then one of my senior suggested me Play with graphs, I started practicing the starting was very smooth as the book started with basic graphs like logarithmic, trigonometric,exponential functions and then it took to me complex graphs which are actually combinations of basic graphs i.e. they contain 2 or more than 2 functions. After continuous practice I actually started playing with graph . Thanks for reading.

Pipeline
INTRODUCTION TO PIPELINE: The efficient and effective movement of natural gas from producing regions to consumption regions requires an extensive and elaborate transportation system. In many instances, natural gas produced from a particular well will have to travel a great distance to reach its point of use. The transportation system for natural gas consists of a complex network of pipelines, designed to quickly and efficiently transport natural gas from its origin, to areas of high natural gas demand. Transportation of natural gas is closely linked to its storage: should the natural gas being transported not be immediately required, it can be put into storage facilities for when it is needed. There are three major types of pipelines along the transportation route: the gathering system, the interstate pipeline system, and the distribution system. The gathering system consists of low pressure, small diameter pipelines that transport raw natural gas from the wellhead to the processing plant. Should natural gas from a particular well have high sulfur and carbon dioxide contents (sour gas), a specialized sour gas gathering pipe must be installed. Sour gas is corrosive, thus its transportation from the wellhead to the sweetening plant must be done carefully. Review the treatment and processing of natural gas. Pipelines can be characterized as interstate or intrastate. Interstate pipelines are similar to in the interstate highway system: they carry natural gas across state boundaries, in some cases clear across the country. Intrastate pipelines, on the other hand, transport natural gas within a particular state. This section will cover only the fundamentals of interstate natural gas pipelines, however the technical and operational details discussed are essentially the same for intrastate pipelines. MANUFACTURING OF LINE PIPES Manufacturing Process UOE Process Submerged Arc Welded pipes are manufactured by "U-O-E': (U-ing_ O-ing, Expanding) process which is considered to be the most suitable process for manufacture of line pipes used by the Oil & Gas Sector. Pre-Forming Inspection Of Plates To detect any steel defect, the steel plate is examined on an on-line ultrasonic machine for lamination and other irregularities before being passed through an Edge Planer where it achieves the required width. Forming Plate Into Circular Shape The edge-planed plate is fed through the crimping press, a 'U' press and '0' press in sequence to form a circular shape. Continuous Tack Welding After having achieved a rounded form, the next sequential process is Continuous Tack Welding; in this process the gap is welded, continuously along the full length of pipe from outside. Unlike other commonly used tack-welding operations, in Continuous Tack Welding process, the seam of the pipe is completely welded thereby eliminating causes of weld defects, including burn-through and weld-cracks in subsequent welding. Inside and outside welding Continuous Tack Welding is followed by Inner Longitudinal Seams welding and Outer Longitudinal Seam Welding under Submerged Arc to avoid any atmospheric contamination. Guide rolls along the length of the seam and ongoing monitor scanning to avoid any possible defect control the welding heads. The configuration of consumables used is compatible to achieve desired quality result on the weld portion. Mechanical Expansion The final dimensions of pipe are obtained by mechanically expanding the pipe. This corrects any deformation such as out-of-roundness or bending that might have occurred during the process. As pipes are expanded from inside, uniform diameters are obtained to facilitate field welding. Simultaneously, residual stress is reduced by expansion. A mechanical expander is used for greater accuracy. Final Inspection A final, meticulous physical inspection is performed, followed by third party inspection (if required). End Protection Metallic bevel end protectors protect the bevel ends of the pipe. Anti Corrosion Coatings Three Layer Polyethylene (3LPE/PP) The Polyethylene coating process consists mainly of Shot Blasting, Induction Heating, Application of Epoxy, Adhesive and Polyethylene layers, Quenching and Holiday Detection of pipes. The Bare pipe is taken from the stacking areas by forklift and stacked on the incoming rack. After pre-heating, the pipe enters the Shot Blasting cabinet where it is cleaned to SA 2- 1/2 Grade surface finish. From the rack, the pipe is then placed on the main coating line conveyor. The dust formed during the Shot Blasting operation is removed in Air Blow and Vacuum Cleaning section. The pipe is then conveyed through induction heating system where temperature in the range of 180oC – 210oC is maintained. The Epoxy primer is applied with the help of a spray gun by electrostatic method. An appropriate reclaim system is provided to remove the excess powder. When exiting through the spray booth, the pipe is coated with a layer of Adhesive followed by various layers of Polyethylene in a number of wraps to build up the total specified thickness. The Polyethylene application is done by an extruder. Manufacturing Specifications / Quality Controls Hydrostatic Testing To meet the technical specification and API standards and guarantee satisfactory performance in the field, the pipes arehydro tested at nominated pressure after mechanical expansion. Testing can be carried out up to a maximum pressure of 4200 psi. Other Tests All pipes at various stages are subjected to a series of stringent non-destructive tests; Ultrasonic Testing and Radiographic examination ensures the quality of weld. Intermediate Ultrasonic Testing, Magnetic Particle Inspection and visual inspection further testify the regularity of quality pattern. Non destructive testing Charpy V Notch testing, Drop Weight Tear Testing (own) is available in-house and iscarried out as per requirements. The pipe is beveled, ready for field welding.
