  The difference between 304 and 316 stainless steel is very commonly misunderstood, or not known at all, and can have a huge impact on the reliability of survey results, and what you’re achieving for your clients. Let’s explore this further. 304 stainless steel contains a mix of chromium and nickel and is slightly responsive to magnetic fields. The addition of the nickel (8-10.5%) modifies the physical structure of the steel and then, theoretically, makes it non-magnetic. However, through extended periods of continuous motion in one direction, and the resulting friction, grade 304 stainless steel can become slightly more magnetic. Additionally, if the steel alloy is mechanically deformed during the manufacturing process the internal structure of the steel may change causing the rods to be partly magnetic from the moment they leave your supplier’s warehouse. They haven’t even seen pay dirt yet. On the other hand, 316 type stainless steel is a molybdenum-alloyed steel and contains a...

 As with all corrosion-resistant alloys, 2205 duplex stainless steel can suffer corrosion when exposed to suitably corrosive conditions. As they contain a higher chromium content than standard 304/316 grades, their Pitting Resistance Equivalent Number (PREN) is higher, indicating increased resistance to pitting corrosion. For instance, the PREN for a duplex stainless steel (Sanmac 2205, SAF2205, 1.4462, F51/F60, S31803, S32205) is 34, whilst that for Alloy 316L (1.4404, S31603) is only 25. Therefore, an appreciable increase in resistance to pitting corrosion can be expected.

  COMMONLY USED BASIC FLANGES The most common and best flange types widely used for many purposes and in many sites are welding neck, slip-on, socket weld, lap joint, threaded, and blind flange. Welding Neck Flange These Flanges are very simple and easy to manage compared to proprietary connections. Their workability is superior, and they are the best design for high-stress service. The welding neck covers the thickness of a wall typically and pipes adjoining with them. The structure of these flanges is explicitly made to work with high pressure and elevated temperature. Some designs contribute a significant part in the smooth transition of pipes’ pressure, depending upon the welding neck flange’s integrity relative to the application. A small projection of the neck from the base is an obvious characteristic in their structure which helps in the strong bonding with the joint, and ultimately pressure of the liquid will flow smoothly according to the design. Certain things like the q...

Welding Neck Flanges  are easy to recognize at the long tapered hub, that goes gradually over to the wall thickness from a pipe or fitting. The long tapered hub provides an important reinforcement for use in several applications involving high pressure, sub-zero and / or elevated temperatures. The smooth transition from flange thickness to pipe or fitting wall thickness effected by the taper is extremely beneficial, under conditions of repeated bending, caused by line expansion or other variable forces. These flanges are bored to match the inside diameter of the mating pipe or fitting so there will be no restriction of product flow. This prevents turbulence at the joint and reduces erosion. They also provide excellent stress distribution through the tapered hub and are easily radiographed for flaw detection. This flange type will be welded to a pipe or fitting with a single full penetration, V weld (Buttweld).

 Like casting processes, forging has also been used since the beginning of civilization to produce metallic goods. In its present form, forging is defined as the process in which metals are shaped using compressive forces.  The general steps of an open die forging process can be enumerated as follows: Rounding of Stock Primarily the heated metal is fixed to an anvil and compressed with lateral and/or vertical dies to form a cylindrical shape. This step is important because it grants structural stability and improves the physical strength of shaft forgings . Setting Dimensional Standards Simultaneous action of multiple dies results in the shaping of a cylindrical metal rod to the desired length, thickness, and shape. Appropriately sized dies are used to deform the bar along its length and provide it the thickness expected of the final shaft forgings .  Consequently, edging and fullering processes are conducted onto the stock. Here, the ends of the material are concentrated...

  The Hot Forging Manufacturing Process The hot forging manufacturing process is performed at extreme high temperature (up to 1150 °C for steel, 360 to 520 °C for al-alloys, 700 to 800 °C for cu-alloys). This temperature is necessary in order to avoid strain hardening of the metal during deformation. Stamping is the most widespread hot forging manufacturing process, where the material is squeezed in a press, between a tool and a die surface. Advantages of Hot Forging The high temperature during hot forging enables the highest possible level of material deformation and the access to complex 3D geometries. Hot forged components possess increased ductility which makes them desirable for many configurations. Also, as a technique hot forging is more flexible than cold forging, since customized parts can be manufactured. The excellent surface quality allows a wide range of finishing work as polishing, coating or painting, tailored to customers’ specific need. Hot forging materials a...
