ASTM A350 Grade LF6 is a vanadium microalloyed steel, which is a derivative of the high-strength low-alloy (HSLA) steel family. The ASTM A350 LF6 forging is primarily used for the manufacture of various piping components covering forged flanges, forged fittings (ASME B16.11) and valves requiring notch toughness testing. There are three classes of Grade LF6 available as per ASTM A350: …

The “wrought pipe high yield” butt welding fittings made to ASTM A860 can be applied to process piping that is designed in accordance with ASME B31.3. Six steel grades for ASTM A860 fittings are available: WPHY 42, WPHY 46, WPHY 52, WPHY 60, WHPY 65, WPHY 70. According to the Code, the design minimum temperature and design maximum temperature for …

Low alloy steel ASTM A333 Gr.6 seamless pipes are widely used in the propane dehydrogenation (PDH) process for the transmission of liquid propane and liquid propylene. The boiling points are -42.1°C and -47.7°C for propane and propylene, respectively. The ASTM A333 Gr.6 steel is working at such a low temperature that Charpy V-notch impact toughness must be taken into account. …

What is Liquid Penetrant Testing? Liquid penetrant testing is a nondestructive testing method for detecting discontinuities that are open to the surface of the stainless steel flange. These discontinuities include cracks, seams, laps, cold shuts, laminations, isolated porosity, through leaks, or lack of fusion. Stainless steel flanges, especially austenitic and duplex, may be subject to cracking if the forging temperature …

The steel angle flange refers to a connection component used in HVAC (heating, ventilation, and air conditioning) ducts and fume exhausting systems. Generally, it can be a circular flange with bolt holes made from a length of steel angle, or a rectangular flange with bolt holes made by welding several pieces of steel angles. Steel angle flanges are bolted up …

General Introduction EN 10222-5 1.4571 flanges generally refer to EN 1092-1 flanges made from Type 316Ti stainless steel forgings, which is a stabilized version of austenitic stainless steel 316. This steel grade corresponds to the steel name X6CrNiMoTi17-12-2. It is equivalent to ASTM A182 F316Ti. Type 316Ti is not a listed material in ASME B16.5 nor ASME B16.47 but it …

In 2020, Shijiazhuang Metalsin was invited to supply a series of piping components to the Tinrhert Field Development Project in Algeria. The engineering, procurement and construction contract EPC1 of this project was awarded to Petrofac. EPC1 is expected to provide a new inlet separation and compression center. The scope of work includes a pipeline network of approximately 400 km to …

The ethane gas is an important petrochemical product which is widely existing in natural gas and petroleum. Since the boiling point of ethane is -88.6°C, the storage of liquefied ethane gas requires low-temperature or cryogenic pressure vessels. Generally, it is stored in spherical storage tanks made from ASTM A203 Gr.D (3.5% nickel steel) plates, which exhibit excellent impact toughness at …

The ASTM A203 Grade D pressure vessel plates are widely used for the construction of methanol scrubber columns, which a key facility in many petrochemical and coal chemical projects. Grade D of ASTM A203/ ASME SA-203 has the nominal composition of 3.5% nickel hence is called “3.5% nickel steel” or “3.5Ni steel”. The UNS number is K31718 with P number …

Piping materials made from ASTM A182 Gr. F5 forgings can be used for power piping which is designed in accordance with ASME B31.1. The forged fittings may be furnished as tee, reducer, elbow, cross, end cap, weld outlet, flange, or other piping components. ASTM A182 F5 has the nominal composition of 5Cr-0.5Mo with P number of 5B. The maximum allowable …

For grades of austenitic stainless steel tubing, made from ASTM A269 TP304, TP304L, TP316 or TP316L, can be used for process piping applications designed according to ASME B31.3. In other words, grades TP304, TP304L, TP316, TP316L are the listed materials of Code ASME B31.3: TP304 – UNS S30400, TP304L – UNS S30403, TP316 – UNS S31600, TP316L – UNS S31603. …

Acetic Acid: Properties & Applications Acetic acid, CH3COOH, also known as ethanoic acid or vinegar acid, is a clear, colorless liquid or crystalline mass with a pungent odor, a melting point of 16.7°C, and a boiling point of 118.1°C. It is miscible with water, alcohol, and ether, and it crystallizes in deliquescent needles. Acetic acid, as well as its derivatives, …
