ASTM Standards for steel pipes
ASTM's steel standards are instrumental in classifying, evaluating, and specifying the material, chemical, mechanical, and metallurgical properties of the different types of steels, which are primarily used in the production of mechanical components, industrial parts, and construction elements, as well as other accessories related to them.

Pipe & fittings Standards

ASTM A335 Chrome Moly Pipe
Heat resistant stainless steel pipe
Stainless Pipes and tubes
Stainless Pipes are made from more than 20 steel grades of various corrosion resistance and are intended for application in conditions of a wide range of corrosion environments and temperatures in heat exchanger.
 
High frequency welding
High Frequency Induction Welded Pipe
High frequency welded pipe( HFW steel pipe) is based on solid resistance heat energy.

Tech & Service of Seamless pipe

Seamless pipes are extensively applied for the nuclear device, gas, petrochemical, ship building and boiler industries. Seamless pipes dominates 65% of market share in Chinese boiler industry.
Condition on delivery:
Term Symbol Explanation
Cold-finished/hard
(cold-finished as-drawn)
BK No heat treatment after the last cold-forming process. The tubes therefore have only low deformability.
Cold-finished/soft
(lightly cold-worked)
BKW After the last heat treatment there is a light finishing pass (cold drawing) With proper subsequent processing, the tube can be cold-formed (e.g. bent, expanded) within certain limits.
Annealed GBK After the final cold-forming process the tubes are annealed in a controlled atmosphere or under vacuum.
Normalized NBK The tubes are annealed above the upper transformation point in a controlled atmosphere or under vacuum.

Weled steel pipe specification, Standard and identification

Welded steel pipe (steel pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp, that are formed, bent and prepared for welding.

Electrical resistance welding

Abrasion resistant pipe specification, Standard and identification

Because the outer surface behaves like mild steel, the product can be cut and welded with proper procedure in the field, configured into a variety of fittings, and can accept the standard end options of flanges, weld rings and couplings.

Fitting specification, Standard and identification

There are different varieties of pipe fittings made of various materials and available in various shapes and sizes.

How a Butt Weld Fitting is Made?

There are numerous processes for manufacturing butt weld fittings, several examples listed as follows.

TEES:
Extrusion method (Hot Forming)

The hot-extrusion process consists of enclosing a piece of metal, heated to forging temperature, in a chamber called a "container" having a die at one end with an opening of the shape of the desired finished section, and applying pressure to the metal through the opposite end of the container.

ELBOWS:
Mandrel method (Hot Forming)

One of the most common manufacturing methods for manufacturing Elbows from pipes. After heating the raw material, it is pushed over a die called "mandrel" which allows the pipe to expand and bend simultaneously.

CAPS:
Deep Drawing method

One of the most common manufacturing methods for caps, where plate is cut out in a circle and formed by deep drawing.



Alloy steel specification, Standard and identification

Alloy Steel pipe contains substantial quantities of elements other than carbon such as nickel, chromium, silicon, manganese, tungsten, molybdenum, vanadium and limited amounts of other commonly accepted elements such as manganese, sulfur, silicon, and phosphorous.

Las bridas son parte integral de muchos proyectos de ingeniería y de plomería. En muchas aplicaciones, los ingenieros necesitan para encontrar una manera de cerrar una cámara o cilindro de una manera muy segura, por lo general debido a que la sustancia en el interior debe ser diferente de la sustancia fuera en la composición o la presión.
 
Seamless steel pipes are produced using an extrusion mold. Welded steel pipes are produced by rolling a sheet of steel into a tube and welding the seam. Seamless steel pipes are less expensive. The third method is casting. Molten steel is poured into a casting mold.
