Couplings pipe hs code

For industrial purposes, in pipeline systems, we usually need to change the direction of transmission; regulate the flow of fluids (oil and gas, water, mud); open or close pipelines, etc. Therefore, to accomplish these activities, steel pipe fittings will be applied.

ASTM A105 (also known as ASME SA 105) covers seamless forged carbon steel piping components for use in pressure systems at ambient and high-temperature service.

Heat treatment the ASTM A105 Fittings is not a mandatory requirement. Although there is an exception for flanges that have an ASTM A105 Fitting Pressure Rating above Class 300. These are flanges of special design, wherein both the design pressure or the design temperature are not known as well as for items over 4 inches NPS and above Class 300. Heat treatment is required, when methods such as normalizing, annealing, normalize and temper, normalize and quench and tempering must be applied.

In addition to being reliable, it has a high tolerance capacity. Our Stainless Steel 304 Forged Fittings are produced using modern technology and high-quality raw materials that assure compliance with international standards.

Stainless steel tee is a common butt welded pipe fitting and an important part of the piping system. According to the diameter of the outlet, there are two types of pipe fittings: equal diameter tee and reducing tee. Equal diameter tee, also known as straight tee, has the same outer diameter of the three water outlets.

Annealing softening begins at approximately 1600¡ãF (871¡ãC) and is fairly complete after 10 to 15 minutes of heating at 1800¡ãF (982¡ãC). Above this temperature, grain growth can be objectionable, although very brief heating at 1900¡ãF will result in complete softening without excessive grain growth. Since the cooling rate has no effect on softening, the material can be water quenched or air cooled.

The alloy can be machined at satisfactory speeds with machine tools commonly used in the industry. Generally, cold drawn or cold drawn stress relief materials are recommended for the best machinability and smoothest finish.

INCOLOY alloy 800 is used in a variety of applications involving exposure to corrosive environments and high temperatures.

Cupro Nickel Forged forgings are annealed at temperatures between 593 and 816 degrees Celsius (1100 and 1500 degrees Fahrenheit). Copper-nickel forged threaded crosses are still widely used in modern shipbuilding.

For applications requiring greater resistance to stress rupture and creep, especially at temperatures above 1500¡ãF (816¡ãC), INCOLOY alloys 800H and 800HT are used.

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.

A bushing is a type of bearing. Generally speaking, “bearings” facilitate movement between two components while reducing friction. Simple in design, a typical bearing has two surfaces that roll against each other, allowing the two mating parts to move without friction.

Grade F22 is a low alloy steel containing nominally 2.25% Chromium. The alloy is widely used in the oil patch wellhead applications for connectors, hangers and block valves. Hardness levels up to 22 HRC are approved to NACE MR0175. The grade is often used as the base metal for clad components.
If supplied to ASTM A182 in the normalised and tempered condition, the 0.2% Proof Stress minimum is 30 KSI.Grade 22 of the ASTM A182 alloy steel is a low-alloy steel that contains 2.25% chromium. Often used as base metal for clad components, the F22 is also used in the oil patch wellhead applications for products such as hangers, connectors, and block valves, among others.

The alloy is also resistant to ammonia-containing atmospheres as well as nitrogen and carburizing gases.

We pride ourselves on being at the forefront of innovation in both product lines and after sales services. This is why we will constantly upgrade our products and services to meet market expectations and demands.

The Inconel Alloy 625 is immune against chloride stress cracking.

Weldolets are the most popular type of branch fittings, belong to the buttweld fittings family, and are available in a wide range of dimensions.

In the manufacturing industry, the production is done by obviously using the best possible quality of crude materials and alloys. It thus tends to offer various good attributes.

Bushings, also known as sleeve bearings, are just one specific type of bearing. They slide on the rod to provide extremely low friction movement. They are ideal for shock absorption and minimise energy consumption, noise and wear.

Bushings are similar to thin tubes most commonly used in machinery with rotating or sliding shafts to increase efficiency and reduce vibration and noise. Bushings can be used for drilling operations in drill stands, hydraulic external gear pumps and motors.

A socket weld is a pipe connection detail in which the pipe is inserted into a recessed area of a valve, fitting or flange. It is mainly used for small pipe diameters and is generally used for pipes with a nominal diameter of NPS 2 or less.

For instance, the use of Carbon Steel ASTM A105 Fittings is prominent in those applications that involved not only environments where the temperatures are high, but also in those applications at room temperature.

INCONEL nickel-chromium alloy 625 (UNS N06625/W.Nr. 2.4856) is used for its high strength, excellent fabricability (including joining), and outstanding corrosion resistance.

Solution heat treatment and annealing are common methods for heat treatment of non-ferrous metals. In my last article, I looked at the heat treatment process for ferrous metals like steel. Today you will learn about the following heat treatment processes, including solution heat treatment and annealing. You will also learn about precipitation hardening, nitriding, cold working, decarburization.

Hastelloy C276 bushings have excellent resistance to strong oxidizing salt solutions such as ferric chloride and cupric chloride. Alloy C-276 has excellent phosphoric acid resistance at all temperatures below boiling point and concentrations below 65%.

The a105 is a mild steel forgings similar to the 20 steel.

The alloy resists a wide range of corrosive environments and has a good resistance to pitting and crevice corrosion. IN625 has good corrosion resistance in various corrosive environments.

Threaded joints are the oldest method of connecting piping systems. Mainly used for small pipe diameters, generally for pipes with a nominal diameter of NPS 2 or less.

It is virtually immune to chloride ion stress corrosion cracking. Sufficient resistance to organic acids such as acetic acid, formic acid and stearic acid.

Monel 400 operates in a wide range of acidic and alkaline environments and has excellent ductility and thermal conductivity. Its properties make it ideal for heavy-duty applications and those requiring a high melting point and toughness in the harshest conditions.

Nickel fittings are manufactured through a hot or cold forming process, which means it can be bent and formed into the correct shape.
