Cage welded elbows or also known as 304 / 316LL cl.3000 socket welded hoses – belong to the group of “high pressure fittings” in which the pipe is welded in the socket (inlet). The socket is welded to the system's tightly constructed tubular form. The Socket Weld (SW) system ensures safety, durability and resistance to system breakage. Such welding is highly praised by welders. During welding, the pipe is inserted into the socket and does not move to ensure better freedom. The weld resists greater pressure. SW accessories allow easy selection of system pressure. Each fitting is stamped with a rating for size, grade, melt and pressure. All SW accessories have 3.1 certification.

Welded shrink brackets are produced on EU production lines, according to ASME, MSS, BS and DIN standards to ensure high quality and technical standards. In there:

ASME standards are a set of American standards spanning the fields of pressure technology, nuclear plants, elevators, construction, standardization, technical design and performance testing,… this set of standards has Controls product quality and ensures pressure of pressurized conduction and storage equipment.
MSS Standards are standards of the Association of Manufacturers of Industrial Valves and Fittings Industry is a non-profit technical association that organizes the development and improvement of industry, national and common law. international standards: Valves – Valve actuators, pipe fittings, flanges, pipe hangers and pipe connectors.
BS standards (British standards) are a collection of standards in the fields of civil construction, materials, chemicals, electronics, consumer products and services, health care, management systems… Standards BS standards include criteria: structure and shape, connection surfaces, materials, pressure limits, dimensions…
DIN standard is the standard of stainless steel.
Standard specifications for cage welding rods
+ Dimensions of stainless steel pipe joints comply with ASME B16.11 standards

+ Forged stainless steel material conforms to ASME A182 standards

+ NPT threads comply with ASME B1.20.1

+ Socket weld accessories meet ASME B16.11 standards

+ Stainless mounting connector conforms to MSS SP-83 standard

+ Insert welded stainless connectors in accordance with MSS SP-79 standards

+ Production facility meets ISO 9001:2008 standards

It can be seen that the cage welding rods fully meet EU standards, ensuring durability, strength, high temperature resistance, high oxidation resistance, and high pressure resistance.

Production materials are mainly stainless carbon steel (most commonly ASTM A105, ASTM A350LF1/2/3/6 for low temperatures, ASTM 182 for corrosive, high temperature applications) and stainless steel (AISI 304 , AISI 316)

TANGIABAO Company provides customers with diverse sizes of pressure cage welding rods of all sizes and requirements. You can propose your own design to fit your system (if there is no available valve that fits your system).

Size criteria for recommended pressure:

1/2″ and 4” for 3000 PSI & 6000 PSI pressure
1/8", 3", 1", 2" for 9000 PSI pressure
❷ Benefits of cage welding
1 – Replace functional threaded hydraulic connectors. In particular, completely eliminate the risk of leakage.

2 – There is no need for any beveling and shrink welding steps before starting to weld.

3 – Completely eliminates the risk of solder joints falling into internal pipes.

4 – Low construction costs because there is no need for special processing to prepare the weld end.
