Analysis of the calculation of stainless steel elbow

At the corner of the pipeline, in addition to the standard elbow, mostly by bending pipes made of stainless steel elbow. Two methods of making stainless steel elbow can be cold and hot bending, cold bending forming is the pipe will be at room temperature; hot bending is the pipe is heated to a specified temperature […]

The introduction of stainless steel cap

The stainless steel cap also called plug or head: is one of the main pressure parts of pressure vessel. The role of the seal is sealed. One is made of tank pressure on the bottom of the container, the two is the end of the stainless steel pipe, not ready to extend forward, then with a header […]

Determination principle of heating temperature of stainless steel elbow

Stainless steel elbow to normalizing and tempering heat treatment, machining port, wall thickness is required to wear and machining allowance. The general allowance is 10% to 20% of the wall thickness of the elbow. The smaller the D ratio of the wall thickness and the section diameter, the better the fitting performance of the die, but […]

Stainless steel reducer industry must improve production skills

Chinese stainless steel reducer industry imbalance, in the current stainless steel reducer output sharply, under the situation of billet origin is serious, first rely on outsourcing, iron ore prices to add stainless steel reducer capital, unable to take part in the intense market competition, to the company production and operation form. Other, first skills economic goals need […]

No mold design of the drawing process for stainless steel tee

Stainless steel tee of non die drawing process is a use of metal flow stress with temperature changes in the nature and the realization of flexible plastic processing technology, is a kind of high precision, high efficiency, low energy consumption, no pollution, no mold, no friction, no lubrication near net forming technology. Different tensile properties of […]

Seamless steel pipe, hot tension reducing mill steel pipe, straight seam steel pipe what’s the difference between the three of pipe

Seamless steel pipe market competition at present, due to the limitation of its production process, the production cost of seamless steel tube has been high, resulting in the gradual decline in its economic benefit. As China’s metallurgical industry technology progress, instead of the seamless steel tube ­ new products also emergence, so new product whether meet […]

For stainless steel reducer without mould design study of the drawing process

Stainless steel reducer without die drawing process is a kind of metal flow stress vary with temperature and change the nature of the implementation of flexible plastic processing technology, is a kind of high precision, high efficiency and low energy consumption, no pollution, no mold, no friction, no lubrication nearly plastic forming technology. Different materials tensile […]

Arc length calculation method of the stainless steel reducer

Stainless steel reducer‘s arc length calculation method for: For example: stainless steel concentric reducer, a big head radius for R1, capitulum radius R2, high for H, The three data on the sheet metal drawing is known. For the convenience of calculation, a big circular arc radius for RD, an Angle for alpha, small head of the radius […]

Stainless steel lap joint stub end material should have high fatigue strength

Gears are stainless steel lap joint stub end products one of the main parts and basic parts, some parts also need to undertake stainless steel lap joint stub end processing, gear failure modes are mainly on the surface of the tooth fatigue crack, wear and broken. Working conditions and failure mode of the gear to stainless steel […]

Development of hydraulic expansion technology for large stainless steel elbow

The basic technological process of stainless steel elbow is that: under the material roll bending welded into a closed ring shell ring shell internal pressure forming segment. Usually the processing technology is to use the mold to suppress the multi block housing, and then welded to complete. Many processes require different fixture or tooling, high manufacturing cost […]
