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 can seamless steel tubes be produced?
Seamless steel tubes are made of ingots or billets made by piercing and are then made by hot rolling, cold rolling or cold casting. Seamless steel tube plays an important role in the steel tube industry of our country. According to incomplete statistics, China's existing seamless tube production enterprises about more than 240, seamless steel pipe units about more than 250 units, with an annual output capacity of about about 4500000 tons. From the caliber, 35% of phi 76, less than phi 159-650, accounting for 25%. From the species point of view, the general use of 1 million 900 thousand tons of pipe, accounting for 54%; oil pipe 760 thousand tons, accounting for 5.7%; hydraulic props, precision pipe 150 thousand tons, accounting for 4.3%; stainless steel pipe, bearing tube, automobile tube 50 thousand tons, accounting for 1.4%.
Q:What place must use galvanized steel pipe to make lighting line?
Galvanized pipe for pipeline laying construction and transformation of lighting, power, telephone, fire protection system in the engineering (made of galvanized steel), for laying, laying can be laid in the dark, the wall can also be installed on the ceiling.
Q:What does carbon seamless steel pipe mean? What is the difference between a seamless 20# and an ordinary one? What is it used in detail?
In general, steel is divided into two groups according to their chemical composition: carbon steel and alloy steel;(1): carbon steel low carbon steel (C = 0.25%); carbon steel (0.25% < C < 0.60%); high carbon steel (C = 0.60%)(2): alloy steel, low alloy steel (alloy is less than or equal to 5%); in steel (5% < < 10% alloy; high alloy steel (alloy) = 10%)Carbon seamless steel tubes are mostly pipes for mechanical engineering structures and pipes for conveying fluids.
Q:What time what time for gas pipeline steel pipe PE pipe
PE pipe must be installed underground, the steel tube can be exposed, when not all PE pipe for pipe laying, overhead installation. But the steel tube is easy to rust, so it can be used where the basic use of PE pipe buried PE pipe.There are galvanized steel pipe and seamless steel pipe, galvanized pipe can only be used for low-pressure homes
Q:Does seamless steel tube have a bend of 135 degrees?
In engineering, it is usually marked as "45 elbow" and has no "135" mark. The angle of the elbow is acute, so there will be no more than 90 degrees elbow.Elbow is a common connecting pipe used in plumbing and heating. It is used for the connection of the bend of pipe, and is used to change the direction of pipe.
Q:What is the outer diameter and wall thickness of the welded steel pipe of national standard DN250?
DN (nominal diameter) 250 is generally the industry said 273, welded steel pipe (spiral steel pipe) thickness is generally between 6-8mm, more common.
Q:What's the use of steel pipe?
No other type of steel can replace the steel tube entirely, but the steel tube can take the place of some sections and bars. Steel pipe is very important to the development of national economy and the improvement of human life quality, much better than other steel products. From the people's daily utensils, furniture, water supply and drainage, gas supply, ventilation and heating facilities to all kinds of agricultural machinery equipment manufacturing, underground resources development, national defense and space use guns, bullets, missiles, rockets and so cannot do without steel.
Q:Can seamless steel pipe and ordinary steel pipe be welded?
Seamless steel tube branch and seamed two, seamed steel pipe welding is formed, all two can be welded together, if you do not allow the use of seam tube cannot connect.
Q:What materials are used in scaffolding pipes?
Safety net with dense green net, safety net of flame retardant standards GB, and safety net of flame retardant performance detection for lighter lit mesh 12 seconds after leaving the fire, flame retardant, continued burning of not more than 4S. The application of 9MM safety net rope, rope, nylon rope woven, each network should be able to withstand the impact of the national standard 1.6KN test.
Q:What does "steel pipe SC" mean?
SC (run in welded steel duitconSC is the line laying mode GB letter of wire is worn steel pipe laying (welded steel pipe, low pressure fluid) SC70 said the conductor by low pressure fluid DN70 welded steel pipe as protection pipe laying, DN70 said the nominal pipe diameter is 70mm, the nominal pipe diameter is 70mm (a series of values, the actual diameter slightly different).
