Our alloy steel ASTM A182 F5 butt weld flanges can be used in auxiliary industrial high pressure services such as condensers, boilers, evaporators, heat exchangers and more.

ASTM A182 Alloy Steel Blind Flanges is a solid disk used to block off a pipeline or to create a stop. It has mounting holes around the perimeter and the gasket sealing rings are machined into the mating surface.

Flanges belonging to ASTM specification are subdivided into various grades that define the properties inherited by these flanges. Also,The ASTM A182 F9 Flanges are having higher versatility degree. The flange is thinner in size and easily fits into compact work spaces and is economical as compared to various other flanges.

Adding nickel adds toughness to the alloy. Similarly adding chromium to chrome moly flanges aids in enhancing other mechanical properties such as temperature strength, hardness, as well as corrosion resistance.

A182-F11 has high thermal strength (¦Äb¡Ý440MPa) and oxidation resistance at high temperature, and has certain resistance to hydrogen corrosion.

Our alloy steel blind flanges are mainly caused by environmental factors such as wind exposure, man-made pollution and high temperature, and are more serious near the ocean, which is the main cause of seawater pollution.

The alloying elements of A335 also impart higher corrosion resistance to the steel pipe. This also makes it the first choice for chemical companies.

We can supply chrome molybdenum alloy flanges sorted by alloy grade, size and pressure.

A193 Grado B7 es el tama?o de empernado mas utilizado, ademas de las tuercas A194 Grado 2H se utilizan para empernar tuberias de acero al carbono. Los pernos A193 B7 estan disponibles en tama?os metricos de M6 a M180 y tama?os imperiales de 1/4 a 7 pulgadas de diametro.

A182 F5 grade slip flanges are known for their low material cost and ease of installation. One of the added benefits of these flanges is that they can also be used as lap flanges if dealing with Type B or C ends.

ASTM 182 is use in pressure systems, Included are flanges, fittings and similar parts to specified dimensions or to dimensional standards, such as the ASME specifications. 182 F5 Cl2 Alloy Steel Flanges are well suited to not only high temperature but also high pressure or a combination of both these applications.

All chrome molybdenum steel sheets are sedated and heat treated in accordance with ASTM A387, which also specifies minimum and maximum levels of the following elements in steel: Chemicals of Carbon, Manganese, Phosphorus, Sulfur, Silicon, Chromium, Molybdenum, Nickel, Vanadium requirements, columbium, boron, nitrogen, aluminum, titanium and zirconium. A387 boards must undergo product, chemical and tensile testing (documented in the MTC or material test certificate) – must meet specific requirements for tensile strength, yield strength and elongation.

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.

There are reducing elbows, long radius elbows and short radius elbows in this grade.These fittings are heat treated during their manufacture.

ASTM A193 Grade B8M Grade 1 Fasteners are similar to Grade B8 but are made of AISI 316 stainless steel instead of AISI 304 stainless steel. Type 316 stainless steel has better corrosion resistance than type 304 stainless steel due to the addition of molybdenum.

SA 182 Socket Weld Flanges are joined by inserting the pipe into the socket end and applying a fillet weld around the top. This allows for better flow of fluid or gas inside the pipe and smooth holes.

Alloy Steel A182 F12 Flanges has excellent resistance to general corrosion, pitting, and crevice corrosion in chemicals containing chlorides and sulfuric, phosphoric, and nitric acids. Alloy Steel F12 Blind Flanges also possesses a great resistance to pitting in chloride solutions, a great resistance to crevice and stress corrosion cracking.

ASTM A194 2H Heavy Duty Hex Bolts are the core product and are in stock. HT PIPE is a leading supplier of ASTM A194 2H Heavy Duty Hex Nuts. These are heavy duty hex nut type bolts as directed by ASTM A-193 specification.

The Alloy Steel F12 Flanges are also very strong due to the annealing of them. Grade F12 Flanges can be supplied in either normalized or quenched and tempered conditions. Alloy Steel F12 Weld Neck Flanges is appropriate to various applications where its different remarkable characteristics are sought-after but a brushed/polished finish is not necessary.

A182 threaded flanges are primarily used for utility services such as air and water. It is similar to a Slip-On flange, but the holes are threaded.

Pipe Fittings are usually socket welded or threaded. The high chromium content gives these forgings fittings very good resistance to moisture erosion

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.

Chrome molybdenum grades P11, P22, P91 and P92 are used in the power industry. Chromium molybdenum grades P5 and P9 are used in petrochemical refining processes. Chrome molybdenum forged fittings and flanges are available in grades F5, F9, F11, F22, F91, F92. Chrome-molybdenum alloy butt welded pipe fittings are available in WP5, WP9, WP11, WP22, WP91, WP92 grades. F11 and F22 materials comply with NACE-MRO 175.

ASTM A193 Grade B7 bolts are considered for applications up to 450¡ãC due to heat treated chrome molybdenum steel. B7 stud bolts are bolts with male threads and a hex head designed to be actuated by a wrench. It can be fully threaded or partially threaded and is supplied with a hex cap.

SA 182 Gr F1 Slip on Flanges also known as SO flanges. This is a flange that slides over the pipe and has an internal design that is slightly larger than the pipe.

We are a specialty metals supplier and value-added service provider dedicated to delivering high-quality chrome moly alloy flanges on time and at a competitive price.

The grade mark consists of the grade symbol “2H” and the manufacturer’s identification mark.

Alloy 32750 is a super duplex stainless steel supplied in hot worked and solution annealed conditions. As a super duplex stainless steel, it combines the desirable aspects of austenitic and ferritic steels. Higher chromium, molybdenum and nitrogen content results in a Pitting Resistance Equivalent Number (PREN) > 40, providing superior pitting and crevice corrosion capabilities to austenitic and duplex stainless steels in virtually all corrosive media, and critical pitting temperature over 50¡ãC.

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.
