Q:What does cathodic protection of steel tubes mean?: Applied current: a macro cell consisting of a protected metal piece and an insoluble auxiliary component. The negative electrode of the battery is connected to the metal to be protected. The power supplies the electrons so that the metal is not corroded by missing points.

Q:Seamless steel tube with the tube with what is the difference?: At present there are some seamed steel pipe seamless treatment tube, it is the weld annealing treatment, eliminate the residual stress of the weld, the weld and base material, the pressure range of basic and seamless pipe is. May also consider the use of.

Q:What's the difference between hot-rolled seamless steel tube and cold-rolled seamless steel tube?: Cold rolled seamless steel pipe (DIAL) in general, steel pipe for low and medium pressure boiler tube, high-pressure boiler steel pipe, alloy steel pipe, stainless steel pipe, oil cracking tube and other steel tube, including carbon thin-walled steel, alloy thin-walled steel, stainless steel, thin steel tube.

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 are the specific differences between flexible pipes and rigid pipes?: From the model:Rigid waterproof sleeve: A, B and C, A type, suitable for steel pipe, B, suitable for cast iron pipe and ductile iron pipe;Flexible waterproof bushings: A and B, A used in the internal walls of buildings, B used in the exterior walls of buildings.In use:

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:Where is the difference between seamless steel pipe and welded pipe?: Seamless pipe pressure is higher, welded pipe is generally in 10 or so MPa, now welded pipe to do seamless processing.

Q:Water, gas, steel pipes, thick steel wire means?: Thick steel wire pipe is the same wire pipe, but the wire pipe is thin tube, easy to damage, so with thick as the outer diameter can protect the wire tube, so called thick steel wire pipe.

Q:What time what time for gas pipeline steel pipe PE pipe: City network is generally medium, are generally. PE pipe high pressure pipe with building the required distance, is generally used around the high pressure pipe laying (high pressure gas supply capacity, and can play the role of peak shaving), the city zone by the supply voltage to the voltage, residential building regulation boxes of low voltage supply to the users.

Q:Seamless steel pipe and welded pipe what is the difference?: Seamless steel pipe is made of solid round tubes and perforated without gaps. The welded pipe is made of steel or strip after welding and has a slit. Generally seamless pipe can be greater pressure on the city.

As the largest strip-steel production base in china, we can get the advantage of having the lowest goods transport cost. Our company covers an area of 80000 square meter, and transportation here is very convenient. We are mainly engaged in the manufacture and management of high frequency straight seam welded pipe. We now have 11 welded pipe production lines, with daily output of2800-3000 tons of welded pipe ranging from DN15--DN200 (1/2--8 inch),and the designed annual production capacity of 800,000 tons.
