Views: 204     Author: Site Editor     Publish Time: 2023-01-19      Origin: Site

Shanghai Zhucheng is a manufacturer in china who supplies and export ASTM A105/A105N material specification forged steel fittings in types of threaded pipe fittings & socket weld fittings. Both of them are available in size from 1/8" to 4".

Carbon steel ASTM A105 pipe fittings are made by forging and machining from round bars, it is suitable in pressure systems at room temperature and high temperature. It enables better structure and improve the mechanical properties. It must also comply with other MSS, ASME, API standards.

Forging Processes

  • Die Forging.

  • Free Forging

  • Cutting Forming. 

Package of ASTM A105/A105N Forged Steel Pipe Fittings

1. Each pipe fittings will be protected by plastic wrap film.

2. Pipe fittings less than 2 inches will be put into cartons for better transportation.

3. Put the sealed carton into the wooden box.

4. All the small packages in wooden box are covered by plastic film to prevent rust during the shipment.



ASTM A105 Socket Weld Pipe Fittings Specification

Socket Weld Fittings

Carbon steel socket weld fittings are high-pressure pipe connection fittings, which is a kind of forged pipe fittings.The pressure rating is Class 3000 , Class 6000, Class 9000.ASTM A105 socket weld fittings are usually suitable for small diameter pipes of 2 inches or less.It is used to connect pipeline by fillet weld,and suitable for projects with high structural strength requirements and high leakage prevention .There are various shapes as following.

 Our hot sale of A105 socket weld fittings are 90 Degree Elbow, Tee and Coupling.

ASTM A105 Threaded Pipe Fittings Specification

Threaded Fittings

Threaded pipe fittings are another type to connect pipes, especially suitable for projects in high pressure environment. The pressure rating can reach Class 2000, Class 3000 and Class 6000. Compared with socket weld fittings,threaded fittings  advantages:

  • Simple connection mode

  • Easy maintenance

  • Low cost

  • Wide application range

There are mainly kinds of threaded products:

  • 45 Degree Elbow

  • BSPP 90 Degree Elbow

  • NPT Equal Tee

  • Reducing Tee

  • Equal Cross

  • Reducing Cross

  • BSP Full Coupling

  • Half Coupling

  • BSPT Union

  • Swage Nipple

  • Hex Nipple

  • Bushing

  • NPT Plug

  • Threaded Cap

  • Threadolet

Correlation of Fittings Class With Schedule Number or Wall Designation of Pipe for Calculation of Ratings


Chemical Composition of ASTM A105 Material 


(1) The sum of copper, nickel, chromium, molybdenum and vanadium shall not exceed 1.00%.
(2) The sum of chromium and molybdenum shall not exceed 0.32%.
For each reduction of 0.01% below the specified carbon maximum (0.35%), an increase of 0.06% manganese above the specified maximum (1.05%) will be permitted up to a maximum of 1.35%.

Mechanical Properties of ASTM A105 Material


Note A – Determined by either the 0.2% offset method or the 0.5% extension-under-load method.

 Other test methods available as listed in A105.

  • Tensile test: the tensile test should be carried executed every time the product being heat treated,

  • Hardness test: customers can check the hardness of any part of the product, and its hardness value should be HB137-187. 6. Water pressure experiment: can be tested according to customer needs

  • Mark:marking of ASTM A105 pipe fittings can be selected according to customer needs and punching marking or laser marking.
