Application

Used for construction of long distance pipelines for combustible liquids and gases, nuclear station pipelines, heating system pipelines, general-purpose pipelines, vessels manufacturing, mechanical engineering and instrumental engineering.

DISTINCTIVES FEATURES

A) The External surface is shot-blasted (Sa 2 1/2) by removing millscale and rust, obtaining metal surface to facilities the adhesion.
B) The pipe is heated in a electric or gas oven at a controlled temperature.
C) The adhesive is then applied by hot meit or copolymer. It binds the polythylene to the steel.
D) Immediately afterwards, the extruded polyethylene/polyprophylene is coated on the pipe.
E) After application of the polyethylene/polyprophylene, the pipe is coated by spraying water.

Q:How much is the tube?
The theoretical weight calculation formula of ordinary carbon steel tube is:The weight of each meter is kg/m= (outer diameter mm-, wall thickness mm) * wall thickness mm*0.02466For example: inventory 20# pipe diameter of 108*4.5 weight per meter:Kg/m= (108-4.5) *4.5*0.02466=11.485In accordance with the diameter of 108*4.5 steel pipe market price is 4500 yuan / ton as an example, we can know the diameter of 108*4.5 steel pipe per meter price: 11.485*4.5=51.68 yuan.
Q:Which is better, galvanized steel pipe or stainless steel?
In rural and urban areas, it is often necessary to wash them in order to keep them in the open. In the heavily polluted industrial and coastal areas, the surface can be very dirty and even rust. But to obtain the aesthetic effect of outdoor environment, it is necessary to use nickel stainless steel. Therefore, 304 stainless steel is widely used in curtain walls, side walls, roofs and other building applications, but in corrosive industrial or marine atmospheres, it is better to use 316 stainless steel. There are several design criteria including 304 and 316 stainless steel.
Q:D108*4 what does "D108" mean by seamless steel tubes? What does "*4" mean?
Seamless steel pipe: a pipe with a hollow cross section, used as a conduit for transporting fluids, such as pipelines for transporting petroleum, natural gas, gas, water, and certain solid materials. Compared withsteel and roundsteelinsolid, flexural torsional strength in the same time, the weight is light, is a kind of economic section steel, widely used in the manufacture of structural parts and mechanical parts, such as the oil pipe, automobile transmission shaft, the bicycle frame and steel construction with scaffold with steel pipe manufacturing ring parts can be improved the utilization rate of materials, simplify the manufacturing process, material saving and working hours, has been widely used to manufacture steel tube.
Q:What is DN50 for welded pipe?
Refers to the use of welded steel pipe made of DN50 steel pipe, refers to the inside diameter is 50mm, the market of common DN50 pipe also refers to the 2 inch pipe, standard pipe: 3.5mm thickness, pipe diameter 60mm, the weight of 4.88kg/m theory. DN50 seamless steel pipe, commonly used in the market, has two specifications: 57mm, 60mm, and if no special instructions, 57mm is commonly used. The outer diameter of the welded pipe is only 60mm this specification.
Q:What's the difference between the fastener type steel pipe scaffold, the floor type steel pipe scaffold and the overhanging type steel pipe scaffold?
Classification is not the only way, fastener type steel pipe scaffolding is divided by force, and the latter 2 are classified according to the structure.
Q:DN80 seamless steel tube, what is the standard thickness?
Commonly used DN80 seamless steel pipe caliber should be 89mm*4mm.
Q:How to identify stainless steel pipe and steel pipe?
Stainless steel (Stainless Steel) is referred to as the stainless steel, the resistance of air, steam, water and other weak corrosive medium or with stainless steel known as stainless steel; while the resistance to chemical corrosion (acid, alkali and salt chemical etching) corrosion of steel called acid resistant steel. Because of the difference in the chemical composition of the two, and make their corrosion resistance is different, ordinary stainless steel is generally not resistant to chemical medium corrosion, and acid resistant steel are generally stainless steel.
Q:Are galvanized steel tubes the same as degaussing steel tubes?
Also known as galvanized steel pipe, hot galvanized and galvanized two kinds, hot galvanized, zinc coating thickness, with uniform coating, adhesion, and long service life. The cost of galvanizing is low, the surface is not very smooth, and the corrosion resistance of itself is much worse than that of galvanized pipe.
Q:Are there specifications for scaffold steel pipe with 48mm * 3.2mm?
However, there are a variety of non GB steel tubes on the market, mainly in the wall thickness, and are thinner than the national standard requirements, you said that thickness may have, but the thinnest only about 2.6mm-2.7mm.
Q:What is a tight steel tube?
The fully enclosed steel tube is called "sleeve connection steel pipe". The English abbreviation is JDG. The sleeve between the pipe and the pipe is fastened by screws. The current specification is the construction and acceptance rules of CECS 120:2007 sleeve steel conduit pipe line
