ASTM A234 is the standard specification for pipe fittings of wrought carbon steel and alloy steel for moderate and high-temperature service. Carbon steel pipe fittings manufactured to ASMT A234 are usually furnished in butt-welding form in accordance with ASME B16.9 or ASME B16.49. There are two carbon steel grades: WPB and WPC, of which ASTM A234 WPB is mostly often used in pipeline industry. The A234 WPB butt-welding pipe fittings include elbows, bends, returns, tees, reducers, end caps, crosses, lap joint stub ends, nipples and couplings.
After forming at an elevated temperature, fittings are cooled to a temperature below the critical range under suitable conditions to prevent injurious defects caused by too rapid cooling, but in no case more rapidly than the cooling rate in still air. Heat treatment temperatures specified are metal (part) temperatures. Heat-treated fittings are to be treated according to paragraph 7 in Specification A960/A960M.

A fitting or adapter is used in pipe systems to connect straight sections of pipe or tube, adapt to different sizes or shapes, and for other purposes such as regulating (or measuring) fluid flow.[1] These fittings are used in plumbing to manipulate the conveyance of water, gas, or liquid waste in domestic or commercial environments, within a system of pipes or tubes.

Outlet fittings are forged products with high strength and clear cost advantages over conventional pipe branching techniques.

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.

Tube caps are used as protective devices designed to protect tube ends of various shapes. The main purpose of using pipe caps is to waterproof connections. They are also used to close the ends of hydraulic or pneumatic pipes and tubes.

The main difference between stainless steel bottle caps and carbon steel bottle caps is the difference in material. The chemicals contained in stainless steel caps will keep the surface of the cap from rusting and corroding for a long time.

Stainless threaded caps are cast from high quality 304/304L/316/316L stainless steel and have female threaded cap ports.

Stainless steel threaded pipe caps cover pipe ends, stop fluid flow and protect pipe threads. These stainless steel caps are commonly used to direct flow to a specific end in a multi-end fitting, and stainless steel cap types include hexagonal and round caps.

The pipe cap is directly welded to the mold at the end of the pipe; the end of the pipe can also be welded with a flange, and then blocked with the flange. If necessary, the flange can be opened to inspect the inside of the pipe. Traditional thick wall gland seat; forged; large diameter by rotation. After maintenance or even wiring is required, use a blind pipe, not later, use a pipe cap. Using a blind plate has the possibility of leakage. After a long time, the screws will rust and die, which is also useless, and the heat pipe is not easy to insulate.

The products we offer meet standards such as ASME B16.11 and ANSI B16.9 and are regularly inspected at every stage of production to ensure high quality, corrosion resistance and high durability.

Their nominal diameters range from 1/8″ to 48″. The standards for these dimensions are ASME B16.9 and B16.28. 304 stainless steel 90 degree elbows are commonly used elbows.

Knowing the finish of these steels can be helpful if your pipes are visible and appearance is on the list of considerations. Stainless steel is usually glossy and can retain that gloss if exposed to weather and other factors. Carbon steel, on the other hand, is darker in color and usually has a matte finish when painted. Unfortunately, it can also rust and look bad if left exposed. Galvanizing is also an option.

Carbon steel pipes are a popular choice for a variety of applications. Ventilation and steam ducts, municipal ducts and sewage ducts are usually made of carbon steel. It helps if you consider additional properties that may be required in chemicals or temperature. The above details can help you determine which steel is right for you.

Steel pipe fittings are made of carbon or alloy steel pipes, sheets, profiles, and have a shape that allows them to function (change the direction or rate of fluid) in a piping system. These accessories mainly include steel elbows (45 or 90 degree bends), tees, reducers (concentric or eccentric reducers), crosses, caps, pipe joints, flanges, gaskets, studs, etc.

ASTM A234 is a standard specification for steel pipe fittings, including carbon and alloy steel materials for medium and high temperature service. It covers seamless and welded types of steel fittings. Steel pipe fittings are used in the manufacture of pressure pipes and pressure vessels. These fitting materials include killed steel, forgings, bar, sheet, seamless or HFW (fusion welded) pipe products with added filler metals.

Tensile Strength and Weight – Both carbon steel and stainless steel are quite high in tensile strength and weight. Piping applications are based on the requirements of the manufacturing program for the application. The ductility of the material depends on the gauge at the time of extrusion, which is similar for both alloys. Typically these fittings are milled; metalworking can expect similar results between the two materials. Manufacturers want materials that have the required ductility, such as adding aluminum to stainless steel, because of its corrosion resistance.

Some types of duplex steel pipe fittings are butt welded fittings, elbows, reducers, couplings, reducers, tees, adapters, joints, and more. Other features of this fitting are good corrosion resistance, pitting and crevice resistance, higher tensile strength, higher yield strength, good toughness, reliability, durability, oxidation resistance, mechanical properties, chemical properties Wait. In addition, it is used in the following applications in chemical industry, pulp and paper industry, condenser, offshore industry, etc.
