Longitudinal welded pipe has the advantages of simple production process， high production efficiency， low cost and rapid development. The strength of spiral welded pipe is generally higher than that of straight welded pipe. It can produce welded pipe with larger pipe diameter with narrow blank， and welded pipe with different pipe diameter with blank of the same width. However， compared with the straight seam pipe with the same length， the weld length increases by ~ and the production speed is low. Welded pipes with large or thick diameter are generally made of steel blank directly，Products Show while small welded pipes and thin-walled welded pipes only need to be welded directly through steel strip. Then after simple polishing，Buenos AiresAlloy pipe GH5188Which brand is good wire drawing is OK. Welded pipe is welded with strip steel， so it is not as high as seamless pipe in its original position. Welded pipe process: uncoiling of raw materials - leveling - end shearing and welding - looper - forming - Welding - removal of internal and external weld beads - pre correction - induction heat treatment - sizing and straightening - eddy current testing - cutting - hydraulic inspection - Pickling - Inspection (strict control) - Packaging - delivery.
1Installing the pipe structure means the complexity of some elements.
jSan AntonioXhy- series high hardness alloy I-beam; Undertake drawings and process wear-resistant pipes（ Φ ≥mm）； Undertake the processing and production of vulnerable parts of cement machinery; Welding technology consultation and service; The wear-resistant layer of alloy wear-resistant plate of high chromium heap welding flux cored wire series is mainly high chromium， as well as manganese， molybdenum， niobium， francium and other components. The alloy carbide formed has strong stability at high temperature.
The fourth is the welding process method to ensure the strict implementation of the special operation method of galvanized pipe. The welding process includes pre welding groove inspection， control of welding process parameters and operation methods， post welding appearance quality inspection， steel mesh，Products Show hook mesh， etc.， but its cost is much higher， and it is rarely used under normal circumstances
HtThere shall be no bending at the welded junction， and there shall be no staggered joint during assembly. Electric welding positioning is generally spot welding. After inspection and straightening， the free conversion method shall be used for welding as far as possible.
How are seamless tubes made?
Ditch cover plate (ditch cover plate) is widely used in municipal roads， garden facilities， residential quarters， schools， stadium pipes and other places.

GNext，Products Show let&#;s introduce the operation steps of roll adjustment during roll change. First of all， we must replace the specification and model of the welded pipe manufacturer. Generally，Buenos AiresAlloy pipe GH5188Which brand is good replace the complete set of rolls. The adjustment process of the rolls is as follows: first， so that the holes of each frame plate are on the same axis and the bottom line of forming ethics meets the technical standards.
CDiscountNext， let&#;s introduce the operation steps of roll adjustment during roll change. First of all， we must replace the specification and model of the welded pipe manufacturer. Generally replace the complete set of rolls. The adjustment process of the rolls is as follows: first， draw an axis from the channel of the generator set to the import and export with stainless steel wire for adjustment， so that the holes of each frame plate are on the same axis， and the bottom line of forming ethics meets the technical standards.
hJ Silicon; it can improve the hardness of steel， but the plasticity and toughness decrease. Electrical steel contains a certain amount of silicon，Reinforcement, galvanized pipe, seamless pipe, welded pipe, alloy pipe, I-beam-Shandong Kaiwen metal material Co., Ltd which can improve the soft magnetic properties
In building construction engineering， welded steel wire mesh is an essential heat preservation and crack prevention material. It has good performance and can take into account the unity between crack resistance and the requirements of face brick for base strength and the stability of heat preservation system.
Galvanized pipe is often seen in our daily life， especially in some construction sites. This product has the advantage of durability when used. It also has the characteristics of surface gloss， uniform zinc layer and no missing plating. Moreover， the cost of hot-dip galvanizing for rust prevention is lower than that of other paint coatings. In addition， this product also has the characteristics of no dripping， strong adhesion， breaking the clean Legion and strong corrosion resistance. Even if it is used in some places where the environment is not good， its service life is also very long， and it also has the characteristics of corrosion resistance. The standard anti rust thickness of hot-dip galvanizing can be maintained for more than years without repair. This is used in some suburban environments. However， in urban or offshore areas， chromizing， boronizing， when the steel structure changes during heat treatment， that is， austenite transforms into martensite， the increase of specific volume will be accompanied by the expansion of workpiece volume， and each part of workpiece will undergo phase transformation successively， resulting in inconsistent volume growth and structural stress. Due to the change of tissue stress， the tensile stress on the surface and the compressive stress in the heart are just opposite to the thermal stress. The magnitude of microstructure stress is related to the cooling rate， shape and chemical composition of martensitic transformation zone materials.
hSan AntonioIt is divided into circular welded pipe and special-shaped (square， flat， etc.) welded pipe.
yZ The surface of hot-dip galvanized parts is bright and beautiful.
Galvanized pipes shall be stored in dustproofto keep clean and new . As a professional manufacturer of galvanized pipe we have produced galvanized pipe products for many years. Welcome friends who need to buy.
