Product Description:

1. Structure of Water Well Drill Pipe Description


We can supply all kinds of drill pipes that are consistent with API SPEC 5DP. Advanced drill pipe production lines can transfer the welding parameters to the best position to ensure the quality of welding zone; the heat treatment process with the feature of internal and external cooling at the same time can make a more reliable and stable mechanical character. Application of automatic weight, length measurement and automatic spray records can ensure products' traceability. Application of thickening and heating lines and 1250 tons of upsetting machine can ensure the thickening size meet the standard of API SPEC 5DR Using of CN furnace for whole pipe body heating and quenching, tempering machine's advanced heat treatment process can ensure the pipe's mechanical character. Tube hydraulic straightening machine ensures the straightness and coaxiality of pipe body.

Q:Water, gas, steel pipes, thick steel wire means?
Often used in water, heating, gas, compressed air and vacuum lines. Can be used in pressure gauge pressure of 0.6 MPa (6 atm) steam pipe and condensate pipeline below, can also be used for conveying non erosive and non flammable and explosive media. Is divided into ordinary (working pressure is 1 MPa pressure gauge, 10) and strengthening (working pressure gauge is 1.6 MPa, 16 ATM) two. Galvanized white iron tube (galvanized iron tube). Non galvanized black iron pipe (black pipe).
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:Seamless steel pipe is how to do it?
Probably with 10, 20, 30, 35, 45 and other high-quality carbon steel, 16Mn, 5MnV and other low-alloy structural steel or 40Cr, 30CrMnSi, 45Mn2, 40MnB and other composite steel hot-rolled or cold rolled.
Q:How to descaling galvanized steel pipe?
Galvanized steel tubes will not rust in principle.... Batch rust with weak acid water immersion, individual can use steel wire brush brush on it.
Q:Is steel pipe made of profiles?
Large steel: large steel, I-beam, channel steel, angle steel and flat steel are hot rolled, round bar, Fang Gang, six angle iron in addition to hot rolling, there are forging, cold drawn and so on.
Q:Fastener type steel pipe scaffold external parts name
Foot board can be made of steel, wood, bamboo and other materials, each quality should not be greater than 30kg. Stamping steel foot board is a kind of commonly used foot board, usually with thick 2mm steel plate pressing, length 2-4m, width 250mm, the surface should be anti-skid measures. Wooden feet can use the thickness of not less than 50mm fir wood or pine production, length 3~4m, width of 200-250mm, both ends should be galvanized steel band two, in order to prevent the wooden foot end of the destruction.
Q:Why seamless steel pipe called seamless steel pipe?
Seamless steel pipe is a hollow section, without the joint round, square, rectangular steel. 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 pipe with a hollow section, as pipe conveying fluid, 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, bike frame and construction using steel scaffolding.
Q:When can I use the PVC pipe and when to use the galvanized pipe?
Galvanized pipes are generally used outside the drying environment or building blocks, and PVC is mainly used for pre embedding in walls or humid environments. If in the ceiling ceiling, below the roof, you need to use galvanized pipe, in the floor below, on the ground you need to use PVC.
Q:Theoretical weight of 25*25*1.5 square steel tubes
The theoretical weight of 25*25*1.5 square steel tubes is 1.075kg/m.
Q:The difference between carbon and welded steel tubes
Seamless steel pipe is made of Steel No. 10-20. It is of high quality carbon structural steelWelded steel pipe is usually welded by Q235 steel plate
