Product Description:

1. Structure of Flat 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.

The flat drill pipe is mainly applicable for the needs of Hydro-hammer percussive-rotary drilling (liquid and gas), which is featured by such advantages as high rigidity, good airtightness, flat external structure, low rotary torsion and less resistance.

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.
Q:What is the difference between galvanized iron pipe and galvanized steel pipe? Or called different, in fact, is referred to as galvanized pipe?
Just name different, all refers to GB/T 3091-2015 "low pressure fluid transport welding pipe" contained in the galvanized pipe.Galvanized pipe means zinc plated, suitable for water, air, heating, steam and gas and other low pressure fluid conveying straight welded steel pipe, longitudinal submerged arc welding (SAWL) steel pipe and spiral seam submerged arc welding (SAWH) steel pipe.
Q:What does seamless steel tube mean? What are the main uses? What are the classifications?
The production process of seamless steel tube in general can be divided into two kinds of hot rolling and cold drawing, cold-rolled seamless steel pipe production process than hot-rolled billet to complex, first to three roller rolling and extrusion to sizing test, if the tube through the cutting machine cutting surface without crack growth response after cutting blank about one meter. Then enter the annealing process, annealing and pickling to use acid pickling liquid, should pay attention to the surface if there are a lot of bubbling, if there are a large number of bubbling pipe shows that the quality is not up to the standard. The appearance of cold rolling seamless steel tube shorter than hot-rolled seamless steel pipe, cold rolled seamless steel pipe wall thickness is generally higher than hot-rolled seamless steel pipe to be small, but the surface looks better than thick wall seamless steel pipe is more bright, rough surface is not too much, not too much burr diameter.
Q:Why can't stainless steel be put together with carbon steel tube?
The bimetallic corrosion is terminated only when one of the three conditions is changed. Galvanic corrosion is related to the contact area of bimetal and the greater the contact area. Corrosion is less. The driving force of galvanic corrosion is the potential difference.[galvanic corrosion] refers to two or more than two kinds of electrode potential of metal in the corrosive medium, and contact with each other caused by electrochemical corrosion, also known as contact corrosion or double metal corrosion.
Q:Is the steel frame on each floor supporting formwork (floor) called full scaffolding?
The scaffold is also called full house scaffolding is a construction process for building a scaffold. Hall scaffolding relative to other scaffolding system density, that is, the house full of shelves. The full scaffolding is more secure than the rest of the scaffolding.
Q:Are galvanized steel tubes the same as degaussing steel tubes?
And the method of magnetic field created by means of electromagnets or permanent magnets. For analysis of residual magnetism, see table (1), select the demagnetizing method and system in combination with the conditions of the construction site (for example, given equipment, etc.). Table 1 magnetic remanence grade and welding conditions
Q:The plastic pipe and steel pipe difference
The steel plastic pipe is a general term, which includes plastic pipe, plastic lined pipe. Plastic pipe external coating, zinc coated and so on in Shanghai, Fujian, Portland, professional in this area
Q:The outer circle of a seamless steel pipe 50 head into the outer circle of the 40 to close
Cold drawn steel tube and cold rolled steel pipe mill is a complete set of equipment which combines cold rolling, cold drawing, cold rolling and cold drawing to produce pipes. It is a unit for deep processing of hot-rolled pipes or welded pipes.
Q:What does "HBB" glass steel pipe mean?
Non electrical corrosion, non-magnetic, suitable for single core cable laying, and steel pipe is a magnetic material, special treatment must be taken to prevent the formation of eddy currents.
Q:DN150 welded steel tubes one meter multiple
The theoretical weight table of welded steel pipe (Kg) can be checked, and the outer diameter and wall thickness can be measured according to the formula.For example: DN150 welded steel pipe, diameter 165mm, thickness 4.5mm, weight kg per meter.Welded steel pipe theoretical weight (Kg/m) = (165-4.5) * 4.5 * 0.02466=17.81Kg
