800H can resist corrosion of many corrosive media. Its high nickel content makes it resistant to stress corrosion cracking in aqueous corrosion conditions. The high chromium content provides better resistance to pitting and crevice corrosion cracking. The alloy has good corrosion resistance to nitric acid and organic acids, but limited corrosion resistance in sulfuric acid and hydrochloric acid. Good corrosion resistance in oxidizing and non-oxidizing salts, in addition to the potential for pitting corrosion in halides. It also has good corrosion resistance in water, steam and mixtures of steam, air and carbon dioxide.

ASTM A194 2h nuts are available in nominal sizes ranging from ?” to 4″. These products are made with heavy duty hex nuts with different proof load stresses for regular nuts and zinc plated nuts. A194 2h coupling nut with 175ksi plain nut and 150ksi zinc plated nut. Fasteners of this grade of material also have high hardness.

Alloy pipe is defined according to the material used in production (ie material), as the name suggests, it is made of alloy pipe; seamless pipe is defined according to the production process (seamless), which is different from seamless pipe is seamless pipe, Including straight seam welded pipe and spiral pipe.

The weld neck flange comprises of a round fitting that extends beyond the rim of the circumference. These flanges, typically manufactured from forging, are actually welded to pipes.

825 is an austenitic Ni – Fe – Cr – Mo – Cu nickel based alloy developed to resist corrosion in very aggressive media.Alloy 825, also known as Incoloy 825, is a nickel-iron-chromium alloy with molybdenum and copper added.

Chrome alloy steel flanges are manufactured in accordance with ASTM A182 F11/F12 and are widely used in nuclear power plants, power plants, water systems, electric power, oil fields, pipeline engineering, natural gas, marine engineering, shipbuilding and other industries. These flanges are harder and stronger than regular steel, but not as corrosion resistant as stainless steel.

Standard ASTM A193 B7 fasteners typically have a common bare metal finish. However, ASTM A193 Grade B7 studs can be galvanized, hot-dip galvanized, xylan coated, teflon coated if requested by the buyer. Coating ASTM A193 B7 fasteners can help improve the corrosion resistance of fasteners. This ASTM A193 Grade B7m bolt is typically used to fasten medium high temperature service materials. These bolts are liquid quenched from 50¡ãF to 900¡ãF and they can be air quenched from -40¡ãF to 900¡ãF.

ASTM A194 Grade 2H bolts are high strength bolts made from carbon steel.

WPHY 52 chemical composition includes metals like Manganese, aluminium, phosphorus, sulphur, vanadium, silicon, nickel, titanium, chromium, molybdenum and copper.A few other moved forward ASTM A860 WPHY 52 properties are its expanded solidness, expanded sturdiness, moved forward weldability, great resistance to hydrogen stretch breaking and its exact measurement.

These ASTM A182 alloy steel F5 F9 F11 F12 F22 F91 pipe fittings are corrosion resistant. ASTM A182 alloy steel F5 F9 F11 F12 F22 F91 fittings also have high dimensional accuracy.

These are available in different types such as Slip On Flanges., Blind Flanges, Weld Neck Flanges, Socket Weld Flanges, Orifice Flanges, Spectacle Blind Flanges, Screwed / Threaded Flanges, Reducing Flanges, and Ring Type Joint Flanges (RTJ).

Alloy 20 (Alloy 20) is an iron-based austenitic alloy developed to resist sulfuric acid corrosion. It has excellent resistance to sulfuric acid corrosion; it has strong resistance to phosphoric acid, nitric acid and chloride environments, chloride stress corrosion, pitting corrosion and crack corrosion. Therefore, alloy 20 has the name of anti-corrosion alloy; it has a wide range of applications: such as: chemical, food, medicine, power production and plastics industries will use it. For resistance to pitting corrosion and chloride corrosion, stress corrosion cracking problems, etc., alloy 20 is often used.

A182 F9 flanges also contain carbon, manganese, silicon, phosphorus, sulfur, molybdenum and 8% chromium in their composition. This combination provides the joint with a minimum tensile strength of 585MPa and a minimum yield strength of 380MPa.

ASTM A193 Grade B7 specification covers the requirements for high strength alloy steel bolting materials for high temperature or high pressure service and other special purpose applications. It is a standard specification that defines typical chemical composition, mechanical properties, hardness requirements, preferential heat treatment, product marking, certification, and other requirements for bolted connections used in pressure vessel service, valves, flanges, and fittings. ASTM A193 defines SI (metric) and inch-pound units.

ASTM A194 bolts include metals such as manganese and silicon, with additions of phosphorus, sulfur, and carbon. ASTM A194 gr 2h bolts are suitable for high pressure or high temperature service, or both. Further machining is possible by centerless grinding or cold drawing.

Alloy steel is steel that is alloyed with a variety of elements in total amounts between 1.0% and 50% by weight to improve its mechanical properties. Alloy steels are broken down into two groups: low alloy steels and high alloy steels. The difference between the two is disputed. Smith and Hashemi define the difference at 4.0%, while Degarmo, et al., define it at 8.0%.[1][2] Most commonly, the phrase “alloy steel” refers to low-alloy steels.

Alloy Steel Flanges are made in different steel alloys. The flanges vary in dimensions and types. There are ? inches through 48 inches of nominal diameter sizes of flanges.

We are a manufacturer, supplier and exporter of Plate Flanges, which are accepted by major industries as a cost-efficient alternative to other types of flanges whose cost increases due to its expensive production pattern.

ASTM A320 L7 Stud Bolts are designed for low temperature performance. These fasteners are commonly used in valves, flanges, fittings and pressure vessels. The ASTM specification recommends a minimum impact value of 20-ft-lbf -150F for ASTM A320 L7 studs.

In case pipeline maintenance, we can remove screws on the flange, take away corresponding pipes or valves. Meanwhile to replace new pipes and valves.

Chromium molybdenum is used in power generation and petrochemical industries for its tensile strength, corrosion resistance and high temperature strength.

The ANSI B16.5 Alloy Steel Slip On Flange is a flange type that allows the pipes to slip onto the flange and makes the connection in a precise locations.

ASME SA335 P9 Alloy Steel Seamless Pipe is certified and tested according to Tensile Test, Transverse Tensile Test, Flattening Test, Metal Structure and Etching Test, Photomicrograph, Hardness Test, etc.
