gost 90deg elbow tee carbon steel pipe fitting

GOST carbon steel butt welded pipe fittings are the most widely used pipe fittings. It is made of high-quality steel pipe and is formed by heating. Carbon steel pipe fittings are divided into carbon steel elbow, carbon steel tee, carbon steel cross, carbon steel reducer (large and small head), carbon steel head (cap) 5 series.
GOST carbon steel butt welded pipe fittings are the most conventional, popular and widely used in Eastern European countries including Russia, Belarus, Ukraine, Kazakhstan and the former CIS countries
    When using, the pipe fittings are evenly welded with the pipeline, so that the pipeline, valve, pump and other equipment are connected to form a complete pipeline system, and the whole pipeline is integrated and starts to work normally.
   GOST carbon steel butt welded pipe fittings are widely used in water, beverage, beer, food, petrochemical, nuclear power, machinery, medical equipment, fertilizer, shipbuilding, waterproofing and other pipeline systems. It is the most widely used pipe fittings in the piping system and equipment of machinery, petroleum, chemical industry, water conservancy, electric power, shipbuilding, air conditioning and other departments. The tube cap is also the end cap on the pressure vessel, which is a main pressure-bearing component of the pressure vessel. The quality of the cap is directly related to the long-term safe and reliable operation of the pressure vessel.
     Our GOST carbon steel butt welded pipe fittings are standardized in materials, finely processed, and priced in line with market demand. According to the needs of different markets and different customers, special shaped manufacturing can fully meet the requirements of customers and markets for different Flanges. And we will inform customers of market needs so that they can quickly expand the market.
The production process of GOST carbon steel butt welding pipe fittings:
1: Put the high-quality steel plate with the required raw materials, put it into the intermediate frequency furnace for heating, and then place it
   On the mold, it is backlogged by a press,
2: Make the shaped pipe fittings blank through the special CNC lathe for pipe fittings according to the drawing. Welding groove processing is performed on both ends of the blank, and a certain angle is reserved, with a certain edge, and the angle and deviation range are strictly implemented in accordance with the requirements of the drawings.
3: Put the elbow blank after shaping and beveling, and put it into the shot blasting machine for shot blasting on the surface of the pipe to remove the iron oxide scale on the inner and outer surfaces.
4: The finished pipe fittings are inspected according to the requirements of the drawings for the thickness and radius of the fingers.

5: Type the qualified elbow on the end face according to customer requirements, including size, steel number, batch number, and identification. And according to customer requirements, the elbows are treated with anti-rust treatment, 1: paint, 2: anti-rust oil, and then put them into wooden boxes or wooden pallets for transportation.
