ASTM A213 T22 Seamless Tubes
ASTM A213 T22 seamless tubes are a specific type of alloy steel tube designed for high temperature service, commonly used in power plants for the fabrication of steam line boilers, superheaters, reheaters, heat exchangers, as well as headers (to distribute steam or water to various parts of the boiler). Designated as UNS K21590 with nominal composition of 2.25Cr-1Mo, Grade T22 …
ASTM B423 UNS N08825 | Incoloy 825 Seamless Tubes
ASTM B423 UNS N08825, also known as Alloy 825 or Incoloy 825, is a nickel-iron-chromium alloy with additions of molybdenum, copper, and titanium. The Incoloy 825 seamless tube provides excellent resistance to various corrosive environments, including those containing sulfuric and phosphoric acids, as well as resistance to chloride-ion stress-corrosion cracking, pitting, and crevice corrosion. Commonly used in chemical equipment, marine …
ASTM A213 TP347 & TP347H Seamless Tubes
SJZ Metalsin supplies ASTM A213 TP347 and TP347H seamless tubes for heat exchangers, boilers and superheaters. As a modified version of the classic 304 stainless steel, niobium is added to oppose chromium carbide precipitation, which means to stabilize the carbon in TP347 stainless steel. The niobium added has significant importance: Improved resistance to intergranular corrosion at elevated temperatures: Niobium can …
ASTM A213 TP304H & TP316H Seamless Tubes
ASTM A213 TP304H and TP316H are the “H Grades” of austenitic stainless steels designed for high-temperature applications. The letter H indicates its higher carbon content as well as the high-temperature service. Seamless tubes made of ASTM A213 TP304H (UNS S30409) and TP316H (UNS 31609) exhibit much better creep strength and creep-rupture strength at elevated temperatures, thus, are widely used for …
ASTM A213 TP304/304L & TP316/316L Tubes
Sizes, wall thicknesses, tolerances & applications SJZ Metalsin supplies a series of seamless austenitic stainless steel boiler, superheater and heat exchanger tubes in the material grades of ASTM A213 TP304, TP304L, TP316, and TP316L. The tubing sizes usually are 1/8″ [3.2 mm] in inside diameter to 5″ [127 mm] in outside diameter. They may be furnished in minimum wall thickness …
ASTM B111 UNS C68700 | Aluminum Brass Tubes
Superior heat exchange solution: ASTM B111 UNS C68700 tubes Condenser tubes made of ASTM B111 UNS C68700, also known as “aluminum brass”, offer exceptional corrosion & erosion resistance, thermal conductivity, and mechanical properties, making them ideal for a wide range of heat exchange applications. UNS C68700 is an alloy containing nominally 77.5% copper, 2% aluminum, and 20.5% zinc with a …
ASTM B622 UNS N10665 | Hastelloy B2 Seamless Tubes
ASTM B622 is a standard specification for seamless nickel and nickel-cobalt alloy pipe and tube. UNS N10665 is a grade specified within this standard. UNS N10665 is also known as Hastelloy B2, which is a nickel-molybdenum alloy with excellent resistance to reducing environments like hydrogen chloride gas, sulfuric, acetic, and phosphoric acids. This alloy is particularly resistant to stress-corrosion cracking …
ASTM B163 UNS N04400 | Monel 400 Tubes
ASTM B163 UNS N04400 seamless tubes for heat exchangers and condensers are engineered from Nickel-Copper alloy UNS N04400, renowned for exceptional corrosion resistance and thermal conductivity. ASTM B163 is a standard set by ASTM International that specifies the requirements for seamless nickel and nickel alloy condenser and heat-exchanger tubes, Monel 400 is a common trade name for the nickel-copper alloy …
Application of ASTM B338 Gr.2 Condenser Tubes in PTA production
What is PTA? Purified terephthalic acid (PTA) is an important organic compound with the chemical formula C₈H₆O₄. It is the refined product of terephthalic acid (a white crystalline solid) and typically exists in the form of colorless crystals or white powder. PTA is a significant industrial chemical, primarily used in the synthesis of polyethylene terephthalate (PET), which is a polyester …
