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.

A pipe fitting, for pipe or pipe, is a very short piece of pipe or pipe with a socket or female pipe thread on one or both ends that allows two pipes or tubes of the same or different sizes to be joined together.

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.

Alloy 600 is not an age hardening alloy; cold working is the only hardening method available.

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.

Socket Weld Elbow and Threaded Elbow Fitting is a fitting installed between two lengths of pipe or tubing allowing a change of direction, usually 180¡ã, 90¡ã or 45¡ã. Nickel Alloy Elbows are available in short and long radius types.

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.

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.

Stainless steel pipe fittings are parts that connect pipes to pipes, their purpose is to connect, control and change direction, divide, seal, support various parts in the piping system, select and prepare suitable pipe fittings to connect together, there are many types, sizes , grades and specifications to meet specific requirements.

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 Curie temperature of this alloy lies within the ambient temperature range and is affected by changes in the alloy’s chemical composition. Caution is recommended in applications requiring strong non-magnetic properties.

Steel tee is a T-shaped pipe fittings that has three branches, normally has two forms with Equal Tee and Reducing Tee (Tee reducer), both are used to divide (combine) the pipelines to adjust the flow rate and change the direction.

We offer products at highly competitive prices and deliver consignment within stipulated time. Our Pipe inventory is available in random lengths or cut to specific lengths to meet your exact requirements.

Under alternating oxidizing and reducing conditions, alloys may suffer from selective oxidation.

ASTM A105, also known as carbon steel, is an iron-carbon alloy with an internal carbon content of nearly 2 percent.

The body of a pipe coupling is typically made of either the same or similar materials as that of the pipes it joins. They may be rigid or flexible depending on the amount of movement the pipe is subjected to and may also be permanent or removable.?

A105 is American ASTM standard number,¡±A¡± stands for common carbon structural steel.ASTM A105 is the most common carbon steel material under ASME/ANSI/API/MSS standard.It¡¯s standard specification for carbon steel forgings for piping applications.

ASTM 182 is used for pressure systems, including fittings, flanges,and similar parts that conform to specified dimensions or dimensional standards such as ASME codes.

HT PIPE is one of the leading manufacturers and exporters of high quality nickel alloy 201 pipe fittings, which are ferromagnetic.

The solution annealing treatment is required prior age hardening / precipitation hardening. The single phase microstructure created during solution annealing is required prior to age hardening, such that only the precipitates formed during age hardening will be present in the final product. The composition, size, and quantities of those precipitates formed during aging will determine the final product’s hardness, strength, and mechanical properties after aging. It is critical that the structure be properly solution treated prior to aging in order to meet all of these requirements.

ASME B16.9 is a widely recognized standard in the industry for fittings, flanges, and valves used in pipelines. The specifications of this standard cover dimensions, tolerances, materials, and markings for varying types of products. One commonly used product is the elbow, and the A234 WPB Long Radius Carbon Steel Elbow is a popular choice.

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.

ASTM A105 Socket weld Fitting 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.

Equal cross, generally for the professional term, four for pipe fittings, pipe connectors, used in the main pipeline to branch pipe.

Our range of Nickel Alloy Fittings, Nickel Alloy Fasteners, High Strength Fasteners includes Butt Weld Fittings, Socket Weld Fittings, Threaded Fittings, Flanges, Fasteners, Outlets, Pipes and Bars. The company successfully engages in supplying industrial accessories and hardware products in a variety of sizes, shapes and sizes to meet customer requirements.

These ASTM A182 alloy steel pipe fittings are suitable for high temperature and high pressure environments.

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

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.

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.

Solution treatment is the most common heat treatment method after stainless steel casting process. The carbide phase is completely or substantially dissolved after the austenitic stainless steel is heated to about 1100 ¡ãC .

These fittings are available in different types such as elbows,couplings,tees crosses,plugs,pipe nipples etc.
