Product Description:

1. Process of High Quality Drill Rod

Process of drill rod generally includes three parts: the pipe end thickening processing tool joints, friction welding, and subsequent processing.

1). The performance and advantages: rod tube ends inside and outside thicker type, the joint use of phosphate or plated steel threaded processing.

2). The product uses: down hole drilling operations, to extend the drill footage;

3). Service: home delivery, tracking services;

4). Packing: steel strapping, compartment plate press-fit.

 

2. Description of High Quality Drill Rod

We can supply all kinds of drill pipes that are consistent with API SPEC 5DP or SY.

Drill Pipe Price can be made as customers' requirements and be equipped with the same type of tool joints.

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:What does "SC50" steel pipe mean in civil engineering?
Welded steel pipe refers to the use of steel or steel plate bending deformation into a round, square and other shapes after welding into the surface of the joint of the steel pipe. The blank used in welded steel pipe is steel or strip steel.
Q:Is there any difference between thermal expansion seamless steel pipe and seamless steel pipe?
One is thermal expansion on a bar, that is, piercing between the bars and expanding the tube with a little bit of mandrel. The other is to expand the formed tube before it is heated so that the defects in the pipe will be enlarged. Comparatively speaking, the quality of the first kind is better than the second, and you should belong to the second kind. Compared with the original seamless seamless tube, the quality and chemical properties are certainly different. The price will be cheaper, too.
Q:What is the weight of hot galvanized steel tubes? DN150 4mm wall thickness
GB/T3091-2008: DN150 welded steel pipe, wall thickness of 6mm, the theory of the weight of welded steel pipe 24.02kg/m, galvanized steel pipe should be multiplied by the weight coefficient after galvanizing, C, DN150, wall thickness of 6mm, C=1.02, DN150, theoretical weight and wall thickness of 6mm galvanized steel 1.02*24.02= 24.5kg/m.
Q:Who knows what is the difference between double submerged arc welded pipe and longitudinal submerged arc welding?
Double submerged arc welding is also a kind of longitudinal submerged arc welding.
Q:What is the outer diameter of the steel tube?
The diameter of a steel pipe refers to the diameter of the steel pipe. The specifications of the steel tube is normal with diameter (diameter and thickness) said, for example 100MM outer diameter and wall thickness of 5MM tube is marked with 100*5.
Q:What's the difference between stainless steel seamless tube and stainless steel welded pipe?
Stainless steel seamless pipe featuresFirst, the product of the wall is thicker, it is more economical and practical, the wall thickness of the thinner, processing costs will be substantially increased it; secondly, the product process to determine its performance limitations, generally low precision seamless steel pipe: uneven thickness, tube inner surface brightness low and high cost of fixed length, and the inner surface pitting and black spots difficult to remove; the detection and plastic third, must be processed offline. Therefore, it has its advantages in high pressure, high strength, mechanical structure and timber.
Q:How to descaling galvanized steel pipe?
Is red rust or white rust, red rust is the base material rust, white rust is Zinc Coating Rust
Q:What's wrong with the 3PP anticorrosive steel tube?
At present, mainly foreign related products come out, for some countries with relatively high ambient temperature, and PP than PE to hard, so as to avoid scratching coating.
Q:What does "HBB" glass steel pipe mean?
Good water resistance, can be used for a long time in wet or water, and the ordinary composite is not water resistant, can only be used in dry environment.Heat resistance, fire resistance is superior to epoxy, glass fiber reinforced plastics and plastic and other materials. It can be used at 130 degrees for a long time, and not burned in case of fire.The utility model has the advantages of insulation, corrosion prevention, no rust, long service life, etc.. Generally up to 50 years, without maintenance.Simple and convenient installation and construction, because this product is light weight, high strength, laying construction method can properly solve the excavation due to road construction, exposed for a long time, prominent problems of city traffic, to achieve the excavation backfill pavement, buried at night, can normal traffic during the day.
Q:What's the gate number of the precision steel pipe?
This kind of steel tube and ordinary hot-rolled seamless steel pipe and cold drawn seamless steel tube in the outer surface is different from the outer surface, and the diameter of the smooth finish of precision steel tube, stainless steel color and the same, inside and outside surface due to manufacturing reasons with a layer of oil.
