HT PIPE is a leading manufacturer of the ASTM A182 Low Alloy Steel flanges as well as the other types of alloys. The ASTM A 182 specification specifies flanges for high pressure services.

The plates are annealed in different condition which offers them strength. Since these plates are to be worked at high temperatures and pressure environment therefore the elements included in it matters a lot. What elements are added in the manufacturing add different properties for example, high level of chromium adds excellent corrosion resistance. It also offers excellent oxidation resistance. Resistant to oxygen is important in petrochemical and gas industries and therefore these plates are used.

A weld neck flange, also called a tapered hub flange or high-hub flange, is a kind of flange that can relocate stress to the pipes, ensuring a decrease in high-stress concentration at the bottom of the flange.

WPHY 52 Pipe fittings are manufactured as per MSS SP 75 shall be furnished in the heat treated condition.We offer a wide assortment of ASTM A860 WPHY 52 Fittings that cater to the prerequisite of different industries such as engineering, chemical, refineries, machine apparatuses, and numerous others.

The chromium content in the A335 p9 pipe makes it highly resistant to corrosion. Therefore, A335 p9 has excellent high temperature oxidation resistance. In addition to chrome, Astm A335 p9 alloy steel pipe coated with black paint or anti-corrosion oil shows good corrosion resistance. It can also be galvanized with zinc. Galvanizing increases its resistance to atmospheric corrosion.

The production of ASME SA182 F9 flanges will be done using alloys with lower carbon content. Reducing the carbon content in these alloys reduces the formation of carbide precipitates. This basically means that alloy steel F9 flanges will no longer be susceptible to intergranular corrosion in the heat affected weld zone.

ASTM A193 Grade B7 Heavy Duty Hex Head Bolts are high strength fasteners made from heat treated alloy steel AISI 4140/4142 quenched and tempered.

ASTM A860 WPHY 60 Fittings are wrought carbon steel fittings that are either seamless or welded with high yield strength. The WPHY 60 indicates that the minimum yield strength of the ASTM A860 WPHY 60 Fittings is 60ksi.

The a182 f9 flange is considered a cost saving option. In addition to these properties, astm a182 f9 is reusable and corrosion free.

Grades 7, 7M, 8 and 8M have 8-10% nickel added. Grade 8 material lacks molybdenum, but Grade 8M ASTM A194 2h material contains all the elements mentioned in the composition, making it the strongest and most expensive class of materials in this grade.
