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.

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.

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.

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.

It is suitable for temperatures up to 1000¡ãF (538¡ãC). Alloy 400 has excellent resistance to cavitation and erosion in fast-flowing brackish or seawater.

According to different varieties and requirements of pipe fittings, forging pipe fittings mainly adopts die forging, free forging and cutting forming processes.

ASTM A105 is an iron-carbon alloy with carbon content of 0.0218%~2.11%. Also called carbon steel.

The working pressure of nickel alloy fittings will vary with the size and construction of the pipe, the type and number of clamps used, the location of the clamps, the correct installation of the clamps, the temperature and the product being conveyed. Fittings are available in the widest range of wall thicknesses and materials in the industry.

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.

Pipe Fittings are usually socket welded or threaded. The high chromium content gives these forgings fittings very good resistance to moisture erosion

At elevated temperatures, the annealed and solution annealed alloys exhibit good oxidation resistance and high strength.

These are available in different types and grades such as Monel 400 Forged Threaded Elbow, Nickel 200 Forged Threaded Equal and Unequal Tee, Inconel 600 Threaded Equal and Unequal Cross, Incolloy 800 Threaded Half and Full Threaded Fittings, UNS S4400 Threaded Reducers, UNS S2201 threaded caps, Hastelloy C276 threaded reducing inserts, etc.

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.

Nickel is a costly commodity, which is why its use in an alloy elevates its cost.

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.

A pipe cap, also known as a head, a plug, or a baffle, is a pipe fitting that is welded on the pipe end or installed on the external thread of the pipe end to cover the pipe. It is used to close the pipe, and the function is the same as the pipe plug.

They can be either cold or hot rolled in different shapes to suit various applications.

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.

Stainless steel has been in use for more than one hundred years.

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 alloy 800 (UNS N08800, W. Nr. 1.4876) is a widely used material for construction of equipment requiring corrosion resistance, heat resistance, strength, and stability for service up to 1500¡ãF (816¡ãC).

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.

A105 is considered a type of forging carbon steel grade.

The alloy exhibits excellent resistance to seawater and brine, making it well suited to marine applications.

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.

Stainless Steel Forged Screwed-Threaded Union Suppliers, ASME B16.5/ B16.9/ B16.11/ B16.36/ B16.25/ B16.49 Stainless Fittings, ASTM A182 Forged Screwed-Threaded Union, threaded pipe fittings & socket weld pipe fittings manufacturers

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.

Carbon steel ASTM A105 socket weld forged fittings are usually ¡°normalized¡± heat treatment, devoid of any internal stresses and thus having superior performances.

Cu-Ni forged threaded fittings are usually supplied as redrawn tubes in the annealed condition. The combination of good ductility and strength provides excellent formability. In addition to this, these forged fittings are also resistant to rust, oxidation, pitting, stress cracking and crack stress.

This alloy is not suitable for highly oxidizing acids such as nitric acid and nitrous acid. It is resistant to sulfuric acid up to 80% and hydrochloric acid solutions up to 20%.

With the specification acting as a guide, it is required that the material follow some requirements. Along with the tensile and yield strength, the ASTM A105 Elbow must adhere to the requirements of the specification for details such as reduction of area, elongation, and hardness requirements.
