Valves Guide

The valve-body ends are designed to connect the valve to the piping or equipment nozzle by different types of end connections, such as butt or socket welded, threaded or flanged. Valve bodies are cast or forged in a variety of forms and each component have a specific function and constructed in a material suitable for that function.

Ultrasonic

Single-layer graphite is called graphene, which does not exist in the free state, and it exists in the form of graphite sheets laminated with multiple layers of graphene. Since the interlayer force of the graphite sheet is weak, it can be exfoliated layer by layer by external force, thereby obtaining a single-layer graphene with a thickness of only one carbon atom.

Conjugate Analysis of Rocket Nozzle Ablation

I. Introduction Historically, ablation in rocket nozzles has been modeled using an approach in which the computation of the convective boundary conditions is decoupled from the thermal response of the ablator (see top diagram in Fig. 1). In this traditional

Nanomaterials

Graphene, a two-dimensional (2D) carbon nanomaterial, has attracted worldwide attention owing to its fascinating properties. One of critical bottlenecks on some important classes of applications, such as printed electronics, conductive coatings, and composite fillers, is the lack of industrial-scale methods to produce high-quality graphene in the form of liquid suspensions, inks, or

Introduction to steam generators—from Heron of

2017/1/1This book details the origins, development, studies, design features, and operational experience of nuclear steam generators. The first part details the history of steam generation, from its origins to its use in power generation and particularly the nuclear power plants.

Stainless steel

The invention of stainless steel followed a series of scientific developments, starting in 1798 when chromium was first shown to the French Academy by Louis Vauquelin.In the early 1800s, James Stoddart, Michael Faraday, and Robert Mallet observed the resistance of chromium-iron alloys (chromium steels) to oxidizing agents.
