Steel pipe piles are widely used in various situations such as supporting piles and friction piles. Especially when it is used as a supporting pile, it can be fully driven into a relatively hard supporting layer, so it can exert the bearing effect of the strength of the entire section of the steel.The main features of steel pipe piles as a large load-bearing part of steel pipe piles are:1. Can withstand strong impact.2. Large bearing capacity.3. Large horizontal resistance and strong lateral resistance.4. Great design flexibility.5. The pile length is easy to adjust.6.

Work procedures after the production of stainless steel stamping elbow finishing.1, according to the requirements of the workpiece and the appearance of the selection of alkaline washing, water-soluble cleaning agent, chlorine solvent sandblasting, shot blasting and other methods for finishing2, generally do not choose the method of acid washing for finishingStainless steel stamping elbow correction.1, the workpiece selection of static load for correction, generally should not be local knocking2,  After correction should be lower than the original tempering temperature stress relief annea

Stainless steel pipe fittings can often be seen in our daily life, because of its good characteristics, loved by people, in use, because of the lack of attention to maintenance, will reduce its service life, so we know how to maintain the stainless steel pipe fittings? Next take a look at it together!Although stainless steel corrosion resistance is good, but if long-term in a corrosive environment, or will be oxidized, the surface of stainless steel for regular cleaning and maintenance, is an important way to maintain its beauty and practicality.

In long-distance pipeline transportation projects, pipeline welding is regularly the maximum vital processing step, so the selection of welding joints and welding techniques at some stage in processing turns into extra vital. In standard welding operations, constant welding, rotary welding, and prefabricated welding are regularly selected.Fixed welding method that the weld joint can not be moved after the pipe institution is paired, and it adjustments with the welding role at some stage in the welding method (horizontal, vertical, elevation, and pitch adjustments).

       When stainless steel is used continuously for a period of time, it is easy to fail and problems like shedding and leaking happen from time to time. And the same series of imported stainless steel joints will have more problems.　　Before using stainless steel quick couplings should check for leaks, if they exist they should be immediately stopped and replaced with new products, while confirming that the gas torch valve is in a closed state before connecting.

With the rapid development of economic development, over the years our country has introduced many large and medium-sized chemical devices, most of these imported devices are using European and American technology, its stainless steel pipe fittings, most of which are used in the United States ASTM, API standards, German DIN standards, British BS standards, etc. At present, a considerable number of domestic fittings factory can produce these corresponding standards of fittings, which is also with the needs of the market This is also the result of the introduction of new technologies.

Stainless steel socket weld tee It is made of stainless steel, so it is called stainless steel pipe fittings.Stainless steel socket weld tee is a stainless steel pipe inserted into the socket part of the pipe fittings and then a circle along the edge of the pipe fittings to do argon arc welding pipe fittings, is a reliable connection in all connection methods. Pipe socket inner diameter = pipe outer diameter.

Stainless steel elbow we are all familiar with, in our daily lives can often be used, for our lives play a very important role, although the life of stainless steel products are very long, but also a certain service life, so how to extend the life of stainless steel elbow? Next, take a look at it together!Stainless steel elbow transportation should use transportation, and supplemented by isolation facilities to reduce the rusting of air and dust on stainless steel products.

Stainless steel threaded fittings are generally used to measure the hardness of Brinell, Rockwell and Vickers hardness indicators.Vickers hardnessStainless steel threaded fittings Vickers hardness test is also an indentation test method, which can be used to determine the hardness of very thin metal materials and surface layers.

The invention and use of stainless steel dates back to the First World War. British scientist Henry Brierley was commissioned by the British government's military department arsenal to study the improvement of weapons.
