Dimension:
       1/2" to 28",             21mm to 720mm
 
Wall Thickness:
        SCH5 to XXS,      5mm to 120mm
 
Standard:
        ASTM, ASME, API, EN, DIN, JIS, GOST etc.

Length:
       Piping lengths from the factory not exactly cut to length but are normally delivered as:
       - Single random length has a length of around 5-7 meter
       - Double random length has a length of around 11-13 meter
       - Shorter and longer lengths are available according to customer's require.

Material Features

-Low carbon steel
    0.05 to 0.309% carbon content.

-Medium carbon steel
   Approximately 0.3-0.8% carbon content. Balances ductility and strength and has good wear resistance, used for large parts, forging and automotive components.

-High carbon steel
    Approximately 0.8-2.0% carbon content. Very strong, used for springs, swords and highstrength wires.
Ultra high carbon steel
    Approximately 3.25-4.0% carbon content. Steels that can be tempered to great hardness. Used for special purposes like (non-industrial-purpose) knives axles or punches. Most steels with more than 2.5% carbon content are made using powder metallurgy.

-Low Temperature Steel
     Low temperature steel alloys having a high toughness and hardness, consisting essentially of from 0.20 to 0.30 wt % of carbon, from 1.20 to 2.00 wt % of silicon, from 0.30 to 0.80 wt % of manganese, from 1.70 to 2.40 wt % of nickel, from 2.50 to 3.50 wt % of chromium, from 0.30 to 0.55 wt % of molybdenum, and the balance essentially iron.

Brief Introduction

Food Extrusion is a form of extrusion used in food processing. It is a process by which a set of mixed ingredients are forced through an opening in a perforated plate or die with a design specific to the food, and is then cut to a specified size by blades. The machine which forces the mix through the die is an extruder, and the mix is known as the extrudate. The extruder consists of a large, rotating screw tightly fitting within a stationary barrel, at the end of which is the die.

Extrusion enables mass production of food via a continuous, efficient system that ensures uniformity of the final product. Food products manufactured using extrusion usually have a high starch content. These include some pasta, breads (croutons, bread sticks, and flat breads), many breakfast cereals and ready-to-eat snacks, confectionery, pre-made cookie dough, some baby foods, full-fat soy, textured vegetable protein, some beverages, and dry and semi-moist pet foods.

Process

In the extrusion process, raw materials are first ground to the correct particle size, usually the consistency of coarse flour. The dry mix is passed through a pre-conditioner, in which other ingredients are added depending on the target product; these may be liquid sugar, fats, dyes, meats or water. Steam is injected to start the cooking process, and the preconditioned mix (extrudate) is then passed through an extruder. The extruder consists of a large, rotating screw tightly fitting within a stationary barrel, at the end of which is the die. The extruder's rotating screw forces the extrudate toward the die, through which it then passes. The amount of time the extrudate is in the extruder is the residence time.

History 

The first extruder was designed to manufacture sausages in the 1870s. Packaged dry pasta and breakfast cereals have been produced via extrusion since the 1930s, and the method was applied to pet food production in the 1950s. It has also been incorporated into kitchen appliances, such as meat grinders, herb grinders, coffee grinders, and some types of pasta makers. A similar functional process occurs when using pastry bags.

Effects

Extrusion enables mass production of food via a continuous, efficient system that ensures uniformity of the final product. This is achieved by controlling various aspects of the extrusion process. It has also enabled the production of new processed food products and "revolutionized many conventional snack manufacturing processes". The extrusion process results in "chemical reactions that occur within the extruder barrel and at the die.
