The flange connection mainly have leakage problem, and the leakage quantity should be controlled within the allowable range of process and environment.

The production of ASME SA182 F9 flanges will be done using alloys with lower carbon content. Reducing the carbon content in these alloys reduces the formation of carbide precipitates. This basically means that alloy steel F9 flanges will no longer be susceptible to intergranular corrosion in the heat affected weld zone.

It exhibits exceptional corrosion resistance in chemical environments containing phosphoric acid, nitric acid, chlorides and sulfuric acid. It also has good mechanical properties at both ambient and elevated temperatures.

Grade B7 is a heat-treated chromium-molybdenum low-alloy steel with minimum tensile strength requirement of 125 ksi (860 Mpa), yield 105 ksi (720 Mpa), and maximum hardness of 35HRC.

While the term alloy steel could even apply to stainless steel grades, the ASTM specification or ANSI standard used to produce the Alloy Steel Flanges would give the buyer details regarding the chemistry details of these products.

ASTM A193 Grade B7 bolts are considered for applications up to 450¡ãC due to heat treated chrome molybdenum steel. B7 stud bolts are bolts with male threads and a hex head designed to be actuated by a wrench. It can be fully threaded or partially threaded and is supplied with a hex cap.

Chromium molybdenum has a better strength-to-weight ratio than steel, which enables designers to use thinner walled tubing or smaller diameter tubing to reduce overall weight.

The flanges can be threaded, ring type joint, lap joint, weld neck or socket welded.

It is almost the same as AISI 4130 chrome-molybdenum alloy steel, but with a slightly higher carbon content. Compared to AISI/ASTM 4130 alloy steel, AISI 4140 steel has a higher carbon content, which provides higher strength and heat treating capability, but also has limited weldability.

Alloy 20 (Alloy 20) is an iron-based austenitic alloy developed to resist sulfuric acid corrosion. It has excellent resistance to sulfuric acid corrosion; it has strong resistance to phosphoric acid, nitric acid and chloride environments, chloride stress corrosion, pitting corrosion and crack corrosion. Therefore, alloy 20 has the name of anti-corrosion alloy; it has a wide range of applications: such as: chemical, food, medicine, power production and plastics industries will use it. For resistance to pitting corrosion and chloride corrosion, stress corrosion cracking problems, etc., alloy 20 is often used.

Alloy steel seamless pipes are used in applications that require high precision for ease of installation and accuracy of operation and application. Different types are used for different mechanical benefits. Most applications require a lot of welding, so welding alloy steel pipes is good for them. Some are low in strength but high in corrosion resistance, and some are also high in strength. We offer high strength low alloy steel pipes in various grades and sizes.

Alloy Steel F12 slip on Flanges are made up of chromium molybdenum steel alloy and therefore have a high rupture resistance. They are also preferred due to their light weight because of the low carbon and high alloy nature.Alloy Steel ASTM A182 flanges are very simple to install and have a low center because the pipe occasionally trips into the flanges after welding.

A/SA387 GR 9CLASS 2 Weldable carbon steel plate for high temperature pressure vessels and boilers. The material benefits from added chromium and molybdenum, which give the steel better corrosion and heat resistance. A/SA387 Grade 9 is intended for use by manufacturers serving the oil, gas and petrochemical industries.

When the F11 flange is heat treated, the alloy steel F22 flange is formed. These flanges have a tensile strength of 655 MPa and a yield strength of 517 MPa.

We offer a comprehensive line of ASTM 335 alloy steel pipe and tubing, known for superior quality and unmatched durability. They are available in different sizes, grades, sizes and shapes.

Alloy steel DIN 1.7335 round bars also offer some other outstanding properties such as perfect finish, dimensional stability, light weight, high load-carrying capacity, longer life, fine dimensions and more.

The connection between two pipes can be directly welded together, but it is difficult to connect together without welding. When the connection part have problems, it will be hard to repair. The same problem also happened between pipe and valve connection.

This is the widely used product in many other industries and is thus manufactured with utmost care and the packaging of this is also done with great care and is then dispatched to various other applications.

Nuts with a nominal size over 1 inch shall be a UNC Series Class 2B fit or an 8 UN Series Class 2B fit. High strength ASTM A194 grade 2H nuts are common in the market and are often replaced by ASTM A563 grade DH nuts due to the limited availability of DH nuts in certain diameters and finishes.

ASTM A335 seamless steel pipe is commonly referred to as chrome molybdenum pipe with chemical elements molybdenum and chromium. Molybdenum can improve steel properties such as strength, elastic limit, wear resistance, impact resistance and hardenability.
