The performance and function of the primary color straight seam steel pipe in the specific use process, the fully demonstrated operational contribution, and the resulting use performance, after painting, spraying white words, the straight seam steel pipe also looks very spiritual and beautiful. Pipe

1. The sealing system has excellent physical properties and corrosion resistance and has a special form of three layers of sealing folds between the main devices, to ensure the tightness of the steel pipeline.2. The rubber inner ring type has special elasticity, which can overcome the axial and radi

The concept of thin-walled spiral steel tube: the strip steel is fed into the welded pipe unit, rolled by multiple rollers, and the strip is gradually rolled up to form a circular tube blank with an opening gap, and the reduced amount of the extrusion roller is adjusted to make the welding seam gap.

The processing of the outer anti-corrosion layer of the steel pipe must be strict to the design requirements and relevant national standards. The rust removal must reach Sa2.5 level, and the primer must be applied within 2 hours after the rust removal is completed. Every time a glass cloth is proces

Thick-walled steel pipes have a wide variety of steel types and specifications, and their performance requirements are also various. All of these should be differentiated as user requirements or working conditions change. Generally, steel pipe products are classified according to cross-sectional sha

1. The arc starting of the stainless steel pipe fittings adopts the reflow method, and the arc ending adopts the method of full arc crater. In the over-scale of arc starting, it should be completed within the slope, and arcing and arcing should not be performed on the surface of the pipeline and the

1. How does the gnawing of straight seam steel pipe happen? What is the effect on welded pipes?The gnawing edge of the straight seam steel pipe usually occurs on the slitting coil. The gnawing edge of the straight seam steel pipe is the appearance of jagged and uneven edges of the steel belt. The st

Project Location: Canada.Product: oil casing.Specifications:84*3*6000mm.Application: oil project construction.Arrival time: 07.12.2022.The steel pipes have arrived in Canada and were put into project use. Many cooperations have given the customer full confidence in THREEWAY STEEL.

The annealing of straight seam steel pipe is to heat the steel pipe to a temperature and keep it warm at this temperature and then slowly cool it to room temperature. There are several types of annealing, such as annealing, spheroidizing annealing, and stress relief annealing.1. Heating the steel pi

1. Organize relevant operators, be familiar with construction drawings and regulations, formulate welding procedures, and compile welding operation instructions.2. Welders should be trained in corresponding projects and have operation qualification certificates for corresponding projects.3. Check wh
