SS 904L socket weld fittings suppliers are used in various industrial processes. The stainless steel 904L socket weld design is commonly used in the demanding environments of chemical and power plants. They are used only in conjunction with as me the pipe and are available in the same size range. They are visually examined for conformity to ASTM, ASME, MSS, DIN, EN, and JIS codes and standards. They are used for lines conveying flammable, toxic or expensive material where no leakage can be permitted, and for steam 300 to 600 PSI. They are used only in conjunction with ASME Pipe and are available in the same size range. They are used in areas where pipe-work is permanent and are designed to provide good flow characteristics. The stainless steel 904L socket weld fittings are produced to several ASTM standards and are manufactured in accordance with ASME B16.11. The B16.11 standard covers pressure-temperature ratings, dimensions, tolerances, marking, and material requirements for forged carbon and alloy steel. Acceptable material forms are forgings, bars, seamless pipe, and seamless tubes which conform to the fittings chemical requirements, melting practices, and mechanical property requirements of ASTM A105, A182, or A350.
The purpose for the bottoming clearance in a Super Duplex Socket Weld is usually to reduce the residual stress at the root of the weld that could occur during solidification of the weld metal and to allow for differential expansion of the mating elements.
The stainless steel 904L socket weld fittings are available in three pressure ratings: Class 3000, 6000 and 9000.These types of connections are socketed so as to have a plain spigot end of the pipe. These are used on valves that are made up of steel, and for such applications that require higher pressure and/or higher temperature in pipelines that do not necessitate repeated disassembling. They ensure leak-proof connections, that too for a long time span.

The types of socket weld fitting are based on their difference in size and shapes. Instinox avails all the types of stainless steel 904l socket weld fittings suppliers, as well as the ones not mentioned below:

Branch outlet fitting socket end
Forged 90 Degree Socket weld Elbow
Forged 45 Degree Socket weld Elbow
Forged Socket weld Equal Tee
Forged Socket weld Unequal Tee
Forged Socket weld Equal Cross
Forged Socket weld Unequal Cross
Forged Socket weld half coupling.
Forged Socket weld Full coupling.

The pipe need not be bevelled for weld preparation.
Temporary tack welding is no needed for alignment because in principle the fitting ensures proper alignment.
The duplex socket weld fitting metal cannot penetrate into the bore of the pipe.
They can be used in place of threaded fittings, so the risk of leakage is much smaller.
Radiography is not practical on the fillet weld; therefore, correct fitting and welding are crucial. The fillet weld may be inspected by surface examination, magnetic particle (MP), or liquid penetrant (PT) examination methods.
Construction costs are lower than with butt-welded joints due to the lack of exacting fit-up requirements and elimination of special machining for butt weld end preparation.

The welder should ensure for an expansion gap of 1/16 inch (1.6 mm) between the pipe and the shoulder of the socket. In the assembly of the joint before welding, the pipe or tube shall be inserted into the socket to the maximum depth and then withdrawn approximately 1/16″ (1.6 mm) away from contact between the end of the pipe and the shoulder of the socket.
The expansion gap and internal crevices left in socket-welded systems promotes corrosion and make them less suitable for corrosive or radioactive applications where solids build up at the joints may cause operating or maintenance problems. Generally require butt welds in all pipe sizes with complete weld penetration to the inside of the piping.
Socket welding is unacceptable for Ultrahigh Hydrostatic Pressure (UHP) in Food Industry application since they do not permit full penetration and leave overlaps and crevices that are very difficult to clean, creating virtual leaks.

Body Wall Thickness – The body wall thickness of socket welding fittings shall be equal to or greater than the values
Socket Wall Thickness – The socket wall average thickness and minimum thickness shall be no less than the corresponding values
Socket Position – The fixed position for the bottom of the socket with reference to the centre line of the socket-welding fitting shall be maintained as required by the dimensions.
Socket Depth – The socket depth shall be no less than the minimum values.
Socket Bore – The inside surface of the socket bore shall present a good workmanlike finish that is free of burrs.
Perpendicular – The end flats of socket welding fittings shall be at right angles to the socket axis.
Width – The forging radius shall not reduce the width of the flat welding surface to less than the value.

The material for forged stainless steel 904L fittings conforms to ASME A182.The dimensions for forged stainless steel fittings conform to ASME B16.11

Products are packaged to ensure that there is no damage during transit. In a case of exports, the standard export packaging is done in wooden cases. All forged fittings are marked with Grade, Lot No, Size, Degree and our trademark. On special requests, we can also, make the custom marking on our products. We also provide with customised packing and packaging according to the buyer needs and wants. We satisfy all the industry rules and requirements.

At Instinox all fittings and flanges are subject to strict inspection at each stage of the production process, from starting material purchasing to product dispatch. They are visually examined for conformity to ASTM, ASME, MSS, DIN, EN, and JIS codes and standards. Upon request, official certified Inspection Agencies can be called in to witness the material reports, dimensions and quality conformity of products. We perform a hundred percent in-house testing of goods before taking it any further.

Manufacturer Test Certificate as per EN 10204 / 3.1B standard, Raw Materials Certificate, 100% Radiography Test Report, Third Party Inspection Report. These reports state the materiality and quality assurance of the products provided at Instinox. Just place the order, we are here to worry about the rest. Order you place is bound to reach us as we have the highest industry capture in the Indian subcontinent, especially in the case of small and medium sector industries.
