What are flanges and fittings?

January 20, 2020 by redearthsteel  

Even with all the latest hi-tech advances, the whole welded pipeline structure has remained the most excellent option for high strain and high warmth applications for decades. In many cases, pipelines in schools, industrial plants, and factories had an advantage over a fully welded system. In particular, they become a closed tank connecting parts of pipes, valves, fittings, and flanges. Also, the welded joint becomes part of the section, minimizing the possibility of leakage, and also extends the service life. Flanges and fittings provide better security, particularly under circumstances of inner pressure. Buttweld fixtures form a permanent metal construction with a pipe, adding up power to sa234 wpb elbow piping structure. Moreover, smoother joints simplify filling and seize up the fewer rooms. Having examined in more detail the types of fittings and flanges designed for use in welded systems, they immediately recognize their recognition and advantage.




What are the fittings?

A234 WP11 Fittings is any part used in a pipeline system to change direction/function and is attached to this system mechanically or by welding. The easiest way to change the course of the pipe is to bend it.


In addition to restricting flow, this method often distorts the shape of a tube. It reduces the strength of the walls. Another process of changing direction is an oblique joint, i.e., straight parts of the pipe are cut into the desired bend and welded together. This type significantly reduces throughput by creating more significant turbulence. A single segment tap is approximately six times the resistance of a valve with a smooth surface. WPL6 Fittings are recommended for most piping systems, where flow rate, internal pressure, and protection against aggressive media are the main factors that influence the design process.



a105 flange is a forged or cast metal ring designed to connect two parts of a pipeline system or create a high-pressure tank, valve, or any other integral flange assembly from a pipeline system. The flanges are connected to the pipeline using a threaded or welded system and are connected by bolts. For example, each pressure reservoir manufactured has at least one flange assembly. This outlet has a predetermined bolt circle and several holes. The flanges are designed and manufactured by the circumference of the bolt mount and the holes for the bolt, so they can be combined. The piping system begins with this flange. The most important part of the spine is its surface. The flange surfaces are machined to provide sufficient contact area with the gasket surface.


Flange classification Surface with a connecting protrusion (raised surface): The contact surface area increases by 0.0625 inches for classes 150 and 300. For a class above 300, the contact area increases by 0.25 inches.


Smooth sealing surface: When attaching 150 or 300 class a182 f11 flanges

to cast iron flanges, a flat surface must be used. Oval-shaped trough surface: Usually used with flanges of class 400 and above, but can be designed for lower grades if desired. Flanges are specially designed for classes 150, 30 0, 400, 600, 900, 1500, and 2500. Common types of flanges are welded with a high neck, union with a low neck, overlap, threaded connection, blind.

Carbon Steel and its characteristic

January 4, 2020 by redearthsteel  

Carbon steel is the main product of the steels that are produced; estimating that 90% of the total production produced to carbon steels and the remaining 10% are alloy steels. These steels are also known as construction steels. The chemical composition of carbon steels is complex, in addition to iron and carbon that generally does not exceed 1%. There other elements which are necessary for their production in the alloy, such as silicon and manganese. The increase in carbon content in steel increases its tensile strength, increases the rate of cold brittleness and reduces toughness and ductility. In addition it should be noted that the carbon content raises the strength of the steel and increases the rate of brittleness to the cold, reducing the toughness and ductility. Based on the amount of carbon they contain, it can be divided into the following categories:



  • Mild steel: It has a carbon percentage of 0.15%, mechanical resistance of 38-48 kg / mm2 and a hardness of 110-135 HB, which makes it easy to handle, weld and deform. Its applications are in materials with cold deformation, elements of machinery of great tenacity, fittings, folded, among others. The applications of this category are pieces of medium strength, drawing, folding, and hardware, among others which can be buy from Alloy Steel Flanges Manufacturers in India.
  • Semi-mild steel: With a carbon percentage it is 0.35%, mechanical resistance of 55-62 kg / mm2 and a hardness of 150-170 HB. This type of carbon steel from Alloy steel pipe fittings manufacturers in India is used in the elaboration of bolts, screws, resistant parts, machinery elements and more frequently used.
  • Semi-hard steel: Its properties give it a good resistance; however it can be subjected to certain types of deformation. It contains a percentage of 0.45%, resistance of 62-70 kg / mm2 and hardness of 280 HB. It can be used for quite resistant parts, transmissions, engine cylinders as well as machinery elements.
  • Hard steel: Its properties are 0.55% carbon percentage, 70-75 kg / mm2 strength and 200-220 HB hardness. Because of these properties it uses in regularly loaded parts, of not very high thicknesses, in transmissions, axles, pensioners, among others.


Characteristics of carbon steel

Carbon steel from stainless steel pipe fittings manufacturers in India has special characteristics that make it a material of great strength and hardness. Thanks to these properties it is widely used in the construction sector. It is a very little ductile material. It is also more prone to corrosion and less expensive than other materials used for cutting.


  • Depending on the carbon content of steel, it is classified into three types. It may seem very little difference but even the slightest variation can completely change the behaviour of the material.
  • Low carbon steel: It contains less than 0.3% carbon. These are relatively soft and not very resistant, but very ductile and malleable.
  • Medium carbon steel: Contains between 0.3 and 0.5% carbon. They can be heat treated by tempering and tempering to improve mechanical properties.


High carbon steel: The latter contains more than 0.5% carbon in its composition. This allows the steel to withstand much more extreme temperatures allowing heat treatments to be applied effectively. Mostly it is used for cutting tools; knives, knives, saw blades, cement bits, pipe cutters, etc.

Stainless steel: Properties and benefits

December 12, 2019 by redearthsteel  

The sa182 f9 contains more than 50% iron, a minimum of 10.5% chromium and a maximum of 1.2% carbon. Its high resistance to corrosion is its main properties.


Main properties of stainless steel

The a234 wp22 steel mostly used in many industries, homes, businesses, among other establishments. This is due to the great properties and features it offers. This metal is considered an almost universal material and ideal for any application and environment. The main characteristics and properties of stainless steel are here.




  • Corrosion resistance


Due to its high chromium substance, stainless steel has good corrosion resistance. It is capable of naturally generating a protective layer when it comes into contact with the environment. This layer of chromium oxide protects the surface and regenerates each time it is damaged.


  • Resistance to extreme temperatures


Compared to other metals, stainless steel from Carbon steel flanges manufacturers in India is capable of resisting extreme temperatures without suffering deterioration or alterations. It can be applied in winter temperatures without risk of embrittlement or breakage. In addition, it has the best fire resistance than other metals and does not give off toxic fumes.


  • Unique and aesthetic material


An A350 lf2 flanges has a great artistic and graceful finish. Many architects use it for their projects and works. In addition, it does not need constant maintenance, since it is very easy to clean. It is enough to apply traditional cleaning products such as detergent, soap and water, and the surface will not be damaged. There are numerous surface finishes: from matte to gloss, through satin and engraving. The finish can also have drawings or be colored, which makes stainless steel a unique and aesthetic material. Architects often choose this material in building works, interior design and for street furniture.


  • Mechanical properties


Stainless steel has excellent mechanical properties at room temperature compared to other materials, an advantage that stands out in the construction sector. It allows reducing the weight per m² or the dimensions of the construction elements. It has good ductility, elasticity and hardness combined with good wear resistance (friction, abrasion, shock, elasticity ...) In addition, stainless steel can be placed on site despite winter temperatures without risk of breakage, which does not prevent lengthening the periods of realization.


  • Recycling


Stainless steel is the "green material" par excellence, recyclable to infinity. In the construction sector, the real recovery rate is almost 100%. Stainless steel from Stainless Steel flanges manufacturers in India is an unalterable product, totally inert in relation to the environment: in contact with substances such as water does not release compounds that can alter the composition. These qualities make stainless steel an ideal material for construction applications, when exposed to the weather: roofs, facades, rainwater recovery systems or sanitary circuits. The long service life of stainless steel meets the needs of sustainable construction: it is the most appropriate solution to ensure maximum longevity of your building.


Additional advantages of stainless steel

The addition of elements such as nickel, molybdenum, titanium and niobium provides additional advantages to stainless steel such as:

  • Resistance to corrosion and creep at high temperatures
  • Resistance and ductility at low temperature,
  • Ease of forming (drawing, folding, hydro-forming, welding, soft welding, etc.)
  • Resistance to extreme temperatures (without risk of breakage)
  • Cleaning, any element made of stainless steel is easy to clean
