Couplings pipe repair

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 A182 Alloy Steel Pipe Fittings are very easy to install and have a low hub due to the pipe going into the fitting before welding.

SS 304 Forged Fittings and SS 304L Forged Fittings products are ideal for various industrial applications, such as gas pipelines, condensers, and nuclear applications. Stainless Steel 304 Forged Fittings have excellent mechanical properties.

Alloy 400 is a nickel copper solid solution strengthened alloy. The alloy is characterized by moderate strength, good weldability, good general corrosion resistance and good toughness.

Little or no corrosion occurs in dry gases such as chlorine or hydrogen chloride at room temperature and high temperature. At temperatures up to 550C in these media, this alloy has proven to be one of the most corrosion resistant common alloys.

Incoloy 800 is a popular choice in the oil and gas industries because it can withstand sour gas and high chloride environments.

SS 304 Forged Fittings are used in various applications that require joining two heavy-duty metal parts. Stainless Steel 304 Forged Socket Fittings can be used in shipbuilding, fats and fertilizers, and the chemical industries.

Forged pipe fittings refer to pipe fittings formed by forging in pipe fittings manufacturing industry. What is said here refers to the latter forging.

Hastelloy C276 bushings are widely used in the harshest environments such as chemical processing, pollution control, pulp and paper, industrial and municipal waste treatment, and recovery of sour natural gas.

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

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

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

Unions Fittings are similar to Couplings. Manufactured as per ASME B16.11, ANSI B16.9, BS 3799 Standards. Socket weld Union and Threaded Unions are available in stock. Alloy 20 Union, Carpenter 20 Union and Incoloy 20 Union is in ready stock with Siddhagiri Metals and Tubes.

The use of branch fittings instead of conventional fittings (buttweld tee, reinforcing pads and saddles) has the following advantages (example Weldolet):

Just 2 welds are needed, instead of 3 (less work and weld inspections)
Accelerated installation time
Less space is required, making the piping system design more flexible
The flow is fully unrestricted, due to the funnel design

In the piping system, stainless steel 304 elbow is a pipe fitting that changes the direction of the pipeline. The chemical composition contained in the stainless steel elbow will keep the surface of the elbow free from rust and corrosion for a long time. According to the angle, the most commonly used are 45¡ã and 90¡ã180¡ã. In addition, according to engineering needs, other abnormal angle elbows such as 60¡ã are also included.

A stainless steel 304 short radius elbow has a radius that is longer than the outside diameter of the pipe it is installed on. These accessories fall under ASTM A403 specification. Their nominal diameters range from 1/8″ to 48″. The standards for these dimensions are ASME B16.9 and B16.28. 304 stainless steel 90 degree elbows are commonly used elbows.

During the aging process, Monel K500 butt welded pipe fittings experience a slight permanent reduction, but a slight warpage occurs due to the entanglement of low heat and slow cooling rates.

HT PIPE is one of the well-known manufacturers of ASME B16.11 threaded bushings, manufactured in a variety of styles and materials, designed to fit a variety of standard and metric threads as well as various types of threaded fittings and assemblies. We offer threaded hex bushings that have excellent resistance to chloride ion stress corrosion cracking, and also exhibit appropriate resistance to a variety of oxidizing environments.

Usually, the structure of a pipe joining consists of the same or identical materials as the pipes it joins. Based on the amount of pressure the pipe is exposed to, they may be solid or fluid, and can even be permanent or temporary.

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

INCONEL alloy 625 is designated as UNS N06625, Werkstoff Number 2.4856 and ISO NW6625 and is listed in NACE MR-01- 75.

ASTM A105 fittings possess a minimum tensile strength of 485mpa with a minimum yield strength of 250mpa. These fitting can be elongated by 22% and possess a hardness of 137 to 187 HBW. Our company is an ASTM A105 Forged Fittings manufacturer in India who make use of top-of-the-line technology to produce the best components in the industry. These coupling can be half or fully coupled. The Full Coupling A105 is employed in connecting small bore pipes. It is utilized in connecting a pipe to another pipe or to a swage or nipple. A105 Half Coupling is utilized for smaller bore branching from a large pipe bore. These couplings can be threaded and welded. A105 Threaded Coupling is preferred in applications where stress on the system is less. We are exporter and manufacturer of Carbon Steel A105 grade for forged pipe fittings.

These alloys possess superior ductility and excellent formability.

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.

a105 is also a material code, belongs to the special steel, is a cold forged steel. The a105 is a mild steel forgings similar to the 20 steel.

HT PIPE is a manufacturer, stocker and supplier of high quality Nickel Alloy 200 Olets, which are manufactured under the expert guidance of our hardworking staff.

Carbon steel forged fittings and flanges are prevalent and common used in industries, the representative material grade is ASTM A105 and A350 LF2/LF3.

SS 304 is the most common austenitic steel and contains both chromium and nickel.

For the pipe fittings of small size, such as tee, tee and elbow of socket welding and thread, the shape is relatively complex, so the die forging process should be used.

It has excellent solderability and can withstand very high pressure and weight. The alloy has excellent mechanical properties at sub-zero temperatures, with a melting point of 2370¡ã – 2460¡ã F, and the product can be used at temperatures up to 1000¡ã C.

Like the other socket pipe fittings, it has a ladder shaped area, so to insert the pipe into the tee branches then welding together. It usually used for small diameter tubing systems.
