TYPES OF FLANGE

1. FLAT FACE FLANGE

एसा फ्लांज कि जिस्मे एक उठा हुआ फेस या रिंग प्रकार संयुक्त निकला हुआ किनारा जैसा रिंग नहीं होता है। उसे FLAT FACE FLANGE कह्ते है!फ्लाट सतह गैस्केट के लिए पूरे सतह के साथ पूर्ण संपर्क करने की अनुमति देती है। ... आमतौर पर गैस्केट को ईपीडीएम या विटॉन जैसी गैर-धातु सामग्री से बनाया जाता है।

2.WELDING NECK FLANGE

एक वेल्ड नेक निकला हुआ किनारा परिधि के चारों ओर एक फैला हुआ रिम के साथ फिटिंग किये होते हैं। आम तौर पर एक फोर्जिंग से मशीनीकृत, इन फ्लैंग्स को आमतौर पर एक पाइप से वेल्डेड किया जाता है। रिम में ड्रिल किए गए छेदों की एक श्रृंखला होती है, जो कि निकला हुआ किनारा बोल्ट के साथ दूसरे निकला हुआ किनारा पर चिपकाए जाने की अनुमति देती है।

ek veld nek nikala hua kinaara paridhi ke chaaron or ek phaila hua rim ke saath ek paripatr phiting ke hote hain. aam taur par ek phorjing se masheeneekrt, in phlaings ko aamataur par ek paip se velded kiya jaata hai. rim mein dril kie gae chhedon kee ek shrrnkhala hotee hai, jo ki nikala hua kinaara bolt ke saath doosare nikala hua kinaara par chipakae jaane kee anumati detee hai.

3.SLIP ON FLANGE

एक निकला हुआ किनारा जो पाइप के ऊपर फिसल जाता है और मजबुती बढाने और रिसाव को रोकने के लिए अंदर और बाहर दोनों तरफ वेल्डेड किया जाता है। कम लागत के कारण weld neck flange की तुलना में इंजीनियरों के लिए काफि पसंदीदा है।

4.RAISED FACE FLANGE

FACE निकला हुआ किनारा प्रक्रिया संयंत्र अनुप्रयोगों में इस्तेमाल सबसे आम प्रकार है, और आसानी से पहचान करने के लिए है। इसे एक उभरे हुए चेहरे के रूप में जाना जाता है क्योंकि गैसकेट की सतह को बोल्टिंग सर्कल के चेहरे से ऊपर उठाया जाता है। ... निकला हुआ किनारा का दबाव रेटिंग उठाया चेहरे की ऊंचाई निर्धारित करता है

5. SOCKET WELDING FLANGE    

सॉकेट-वेल्ड पाइप flanges आमतौर पर उच्च दबाव पाइप के छोटे आकार पर उपयोग किया जाता है। इन पाइप फ्लैंग्स को सॉकेट एंड में पाइप डालने और शीर्ष के चारों ओर फिलाट वेल्ड लगाने से जुड़ा हुआ है। यह पाइप के अंदर एक चिकनी बोर और द्रव या गैस के बेहतर प्रवाह के लिए अनुमति देता है।

6.BLIND FLANGE:

is tarah ke flange ka upyog kisi bhi pipeline me dummy ke rup me istemaal kiya jaata hai.

taaki pipe ke andar jo bhi material hai vo aage na ja sake.

What does a structural engineer do?

What does a structural engineer do?

Structural engineers often work alongside civil engineers and architects as part of a construction team. "In a nutshell," according to the Institution of Structural Engineers, "if a structure was a human body, then the architect would be concerned with the body shape and appearance, and the structural engineer would be concerned with the skeleton and sinews."

Structures must be able to deal with the conditions in which they are built. A house in Canada must have a roof that can bear the weight of heavy snow and a stadium in California must be able to withstand earthquakes, for example. When building bridges, designers must take into account the conditions of terrain, wind, water and traffic volume. Structural engineers consider all of these factors and provide technical advice about the project.

"Structural engineers battle gravity, wind, snow and rain every day to provide the world with outstanding structures," Kate Leighton, a structural engineer, said in "Careers in Structural Engineering, a publication of the Institution of Structural Engineers. "They are experts at solving problems, meeting challenges and providing creative solutions."

Structural engineers "design roof framing (beams, rafters, joists, trusses), floor framing (floor decks, joists, beams, trusses, girders), arches, columns, braces, frames, foundations and walls," according to the National Council of Structural Engineers Association. "In bridges, they design the deck — or riding surface, girders or stringers, and piers. The materials they use include steel, concrete, wood, masonry, and aluminum. Engineers design the structure to resist forces from gravity, earthquakes, high winds, water, soil, collisions and blast explosions."

A structural engineer's job includes:

●       Analyzing blueprints, maps, reports, and topographical and geological data;

●       Estimating the cost and quantities of materials, equipment and labor;

●       Computing load and grade requirements, water flow rates and material stress factors to determine design specifications;

●       Inspecting project sites to monitor progress and ensure the project is being constructed according to design specifications;

●       Conducting studies of traffic patterns or environmental conditions to identify potential problems and assess how they will affect the project.

Critical skills that a person needs in structural engineering include an in-depth understanding of physics and mathematics. A structural engineer must also know the properties of various materials, such as their density, hardness, tensile strength, bulk modulus and bending strength. They need to be able to calculate how different materials will perform under stresses such as compression, tension, bending and twisting, as well as under various environmental conditions of temperature, pressure, corrosive gases and liquids, and even radiation. They also need to be able to predict how these materials will perform over an extended period of time.

Structural engineers rely increasingly on computer-aided design (CAD) systems, so proficiency with computers is essential. In addition to speeding up the drafting process, CAD systems allow for quick and easy modifications of designs and three-dimensional (3D) visualization of finished parts and assemblies.

  Structural engineering deals with the research, planning, design, construction, inspection, monitoring, maintenance, rehabilitation and demolition of permanent and temporary structures as well as structural systems and their components.  It also considers the technical, economic, environmental, aesthetic and social aspects of the structures.

  The structure may include buildings, bridges, in-ground structures, footings, frameworks and space frames including motor vehicles, space vehicles, ships, airplanes and cranes.  They can be made of any structural material, including composites and novel materials.

  Structural engineering is a creative profession that contributes significantly to infrastructure, industry as well as residential and recreational development.

  Structural engineers calculate the strength and draw diagrams of the structures to ensure that they are strong enough to avoid loading.  The most common structures are with buildings and bridges, but tunnels, walls, earth embankments, large tanks and silos as well as capturing mining structures are also part of the work of a structural engineer.  Specialist areas include oil drilling platforms and related infrastructure, shipbuilding and aircraft design.

  Structural engineers typically work in teams and look at the way a structure is to be built.  They ensure that the buildings are strong enough to withstand the load imposed by the natural forces and nature of its use.  Through research and testing of both form and material, new solutions are developed that promote safer, more environmentally friendly buildings and structures.

  Some structural engineers work in the design of structures (supervise strength calculations and drawings), others specialize in building structures and some work in research.  Structural engineers typically work with architects, builders, mechanical, electrical and chemical engineers to ensure that all parts of the structure are safe and capable of accomplishing their intended function.  They also ensure that the structures use the appropriate materials efficiently.?

Fabrication Work

Fabrication Work ||Metal fabrication||Sheet metal fabrication || Fabrication design ||

Fabricate is to place things along out of artificial or natural elements or elements. Metal Fabrication is the building of metal structures by cutting, bending, and aggregation processes. It's a price additional method that involves the creation of machines, parts, and structures from varied raw materials. Prototype. 

Metal fabrication is that the method of building a structure out of metal mistreatment varied processes and so aggregation final items. Metal fabrication outlets usually provide many services revolving around the raw materials. Jobs during this trade fall on each a part of the method, from the look section to active fabrication work to final installation.There area unit several subtypes of metal fabrication that area unit usually characterised by the sort of processes they are going through to achieve completion, like cutting, machining, punching,

The producing method is split into fabrication (making parts), assembly (putting elements along to form components), and assembly (putting the elements along to make the ultimate product).The fabrication method contains many totally different procedures, every specific to a specific variety of raw material—sheet metal, plastic, or Al.
Once the constituent elements are created, they're assembled; major sub-assemblies, or elements, embody the transmission, the pump, the spin and washtubs, the balance ring, and therefore the painted elements.
