Applicability of ASTM A333 Gr.6 Pipes in PDH Plant

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. …

Liquid Penetrant Testing for Stainless Steel Flanges

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 …

Steel Angle Flanges for Ventilation Ducting

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 …

EN 10222-5 1.4571 | Type 316Ti Flanges

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 …

ASTM A182 F60 Forgings for Filter Vessels

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 …

ASTM A203 Gr.D Plates for Ethane Storage Tanks

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 …

ASTM A203 Gr.D Plates for Methanol Scrubbers

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 …

ASTM A182 F5 Forgings for ASME B31.1 Power Piping

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 …

ASTM A269 Tubing Used for ASME B31.3

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. …

ASTM A240 304/304L Plates | Acetic Acid Corrosion Data

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, …

SS 304/304L Cast Valves | Petroleum Corrosion Data

Petroleum Corrosion Resistance Data Stainless steel 304/304L cast valves denote valves with body and bonnet made of ASTM A351 Gr. CF8 or Gr. CF3 high-alloy austenitic castings. Both CF8 (304) and CF3 (304L) have the same nominal composition 18Cr-8Ni but different UNS designation, J92600 and J92500, respectively. The main difference is that CF3 has much lower carbon content. Another conventional …

Postweld Heat Treatment for ASTM A335 P11 pipes

Construction Codes & Significance Seamless pipes made of low-alloy steel ASTM A335 Grade P11 can be used for power piping (ASME B31.1) or process piping (ASME B31.3) at elevated temperatures. After joining the two ASTM A335 P11 pipes together by a welding process, postweld heat treatment (PWHT) is required. The PWHT is used to avert or relieve the detrimental effects …
