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 forged fittings is heavier, thicker and are intended for heavy industrial use. It is made up of forged carbon steel. Forging steel process makes the fitting very strong. Carbon steel is heated to molten temperatures and placed in the dies.

The length of the pipe nipple is usually specified by the overall length with threads. It may have a hexagonal section in the center for the wrench to grasp (sometimes referred to as a ¡°hex nipple¡±), or it may simply be made from a short piece of pipe (sometimes referred to as a ¡°barrel nipple¡± or ¡°pipe nipple¡±).

Stainless steel 304 is a type of stainless steel that is resistant to corrosion and rusting. Stainless Steel 304 Forged Fittings are used for connecting two pipes or tubes together and can be made from a variety of metals, including copper, brass, aluminum, or stainless steel.

Most iron-based metals react with water to produce the reddish iron oxide known better as rust. The oxygen atoms in the water pulls iron off of the base metal to form the porous rust structure with no real strength.

Boss is a pipe attachment detail in which a pipe is inserted into a recessed area of a Valve, fitting or flange. In contrast to buttweld fittings, Socket Weld Fittings are mainly used for small Pipe Diameters (Small Bore Piping); Generally for Piping whose Nominal Diameter is NPS 2 or smaller.

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.

NAS625 (NCF625, UNS N06625) is a nickel-chromium-molybdenum alloy with an additional of niobium. Matrix stiffening provided by molybdenum and niobium results in high strength. The alloy resists a wide range of severe corrosion environments. It also offers resistance to high temperatures. It also demonstrates remarkable protection against corrosion and oxidation. Its ability to withstand high stress and a wide range of temperatures, both in and out of water, as well as being able to resist corrosion while being exposed to highly acidic environments makes it a fitting choice for nuclear and marine applications.

SS 316H Forged Tee is a short pipe with a transverse connection at right angles to the pipe. Mostly used to connect multiple pipes to one pipe with two outlets. Usually, they contain an entry. The SS 316 Forged Cross is used to combine or distribute flow by connecting pipes at cross joints and splitting the flow from each pipe.

The 316 stainless steel receptacle is an integrally reinforced branch connector that is more secure and reliable than other traditional branch connectors. Easy to use, good performance, durable and other advantages, well received by customers.

You source everything directly from manufacturers and shareholders! The average daily sales volume of stainless steel pipes in our inventory is about 40 tons. We believe in offering our clients substantial discounts and work closely with them on all their project requirements. We always offer the most competitive stainless steel 90 degree elbow prices to potential and existing customers.

Stainless steel does not rust because Cr and Fe in it are oxidized to form a dense passive film to prevent further corrosion.
AISI 304 stainless steel has excellent corrosion resistance in mild atmosphere and fresh water, and even the surface will not rust. But it is not resistant to halide (such as chloride, fluoride, etc.) corrosion, because halide easily penetrates the passive film, making stainless steel lose its resistance.

A?threadolet?is the same basic design as a “weldolet.” However the main difference is the fitting has a female threaded connection to mate to the branch connection. This makes a 90¡ã branch and comes in full size or reducing for a straight piece of pipe.

Annealing is a heat treatment process which alters the microstructure of a material to change its mechanical or electrical properties. Typically, in steels, annealing is used to reduce hardness, increase ductility and help eliminate internal stresses.

If hardened Monel 400 is the goal, cold working with a soft tooling material is the only option. By cold working, mechanical stress is used instead of heat to change the shape of the metal.

Coupling is a kind of fittings commonly used in industrial pipe connection.

This alloy is most commonly used in a range of environments from mildly oxidizing to neutral and moderately reducing conditions. Other areas of application for this material are marine environments and other non-oxidizing chloride solutions.

Typical applications for copper-nickel 70/30 forged fittings are condensers, seawater piping, power plants, exchanger housings, etc. These cupronickel 70/30 fittings can be further customized in thickness and size according to customer specific requirements.

Hastelloy C276 is one of the few materials that can withstand the corrosive effects of wet chlorine, hypochlorite and chlorine dioxide.

To recover the inherent corrosion resistance of stainless steel castings. The corrosion resistance of stainless steel decreases after investment casting. The corrosion resistance of stainless steel castings recovered to the optimum state after solution treatment.

Hastelloy C276 is resistant to localized corrosion such as pitting and stress corrosion cracking.

This specification covers standards for forged carbon steel piping components, that is, flanges, fittings, valves, and similar parts, for use in pressure systems at ambient and higher-temperature service conditions.

At elevated temperatures it offers resistance to oxidation, carburization, and sulfidation along with rupture and creep strength.

To make the structure and composition of stainless steel castings uniform, which is especially important for raw materials, because the casting temperature and cooling rate are not the same, resulting in inconsistent microstructure. With high temperatures, the atomic activity intensifies and the ¦Ò phase dissolves, and its chemical composition tends to be uniform. A uniform single-phase structure is obtained after cooling quickly .

Tee is also known as pipe fitting tee or tee pipe fitting, tee joint, etc. Used mainly to change the direction of the fluid, used in the main pipe to branch pipe.

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.

Hastelloy C276 has a low carbon content to minimize grain boundary carbide precipitation during welding to maintain corrosion resistance in the heat affected zone of the welded joint

Hence, materials with low carbon content such as ASTM A105 Fittings are not recommended to be used in those applications which have the need to be constantly exposed to a range temperatures above this value.

Hastelloy can be used with all common welding methods, but oxyacetylene and submerged arc processes are not recommended when the manufactured product is intended for corrosion service.

At HT PIPE. we invest in premium resources and dependable technology and machinery. NISPL has given an impetus to several industries during the last three decades, through its outstanding products and extraordinary services.

Stainless elbows are curved connecting pieces that join straight lengths of pipe, commonly at a 90¡ã or 45¡ã angle, allowing obstructions to be avoided in plumbing, ventilation, welding, and automotive applications.
