Cleaning procedure and precautions for stainless steel pipe fittings

Stainless steel pipe fittings with constant use and expansion, in the specific process of using produced good operating performance, fully in accordance with the important guarantee parameters used, stainless steel pipe fittings to pay attention to certain steps and methods in the use acid washing process in need.

The classification of industrial stainless steel pipe fittings

Industrial stainless steel pipe fittings refers to the connection of two parts of the pipeline or other pipe fittings items, is an important industrial pipe fittings, including tee, cross, elbow, reducer, head, flange, belonging to the fabricated metal products industry . Many types of industrial metal fittings, according to different standards can be divided into different types. According to the current stage of China'sstainless steel pipe fittings manufacturing enterprises of the product classification standards, according to its function will be divided into industrial stainless steel pipe fittings: stainless steel elbow, stainless steel flange, stainless steel tee, stainless steel cross and stainless steel reducer.

Continuous casting slab process for stainless steel pipe fittings

The best way to improve the quality of stainless steel pipe fittings is by ingot into a casting process. Due to the improvement of the continuous casting process quality control methods, this method has become a necessary means to improve the quality of products.

Process for pickling and passivation of stainless steel pipe fittings

Stainless steel pipe fittings for pickling passivation operation steps:
1. The preparation work
2. Chemical degreasing

Hot bending method for stainless steel pipe fittings

Stainless steel pipe fittings in heating condition, to bend called hot bending. The bending of the stainless steel pipe fittings and can be divided into sand filling without buckling of hot bending and buckling is not filling sand hot bending.

Cold bending method of the most common stainless steel pipe fittings

D 150 mm stainless steel pipe fittings or less, because the stainless steel pipe bending without heating, the stainless steel tube bending aluminum pipe and copper pipe, cold bending heat is more appropriate.

Thread step and methods of stainless steel pipe fittings

Thread step and methods of stainless steel pipe fittings are as follows:
The thread sets before the first choice corresponds to the diameter of the die, according to sequence number 4 will die to turn into the hinge plate die chamber. Prior to loading, pay attention to the hinge plate on the iron sweep.

Micro-irrigation system calculate the diameter of the stainless steel pipe fittings at all levels

At all levels of micro-irrigation system, determine the diameter of the stainless steel pipe fittings and pipe section is one of the main task of the hydraulic calculation. Micro-irrigation system of capillary only 10 mm in diameter, and 12 mm, 15 mm, 20 mm, 25 mm to wait for a few kinds, in can choose directly based on the experience in the design of micro-irrigation system. Stem, the diameter of the pipe section should be calculated according to by the flow section O flow relations with stainless steel pipe section size is:

How to eliminate rebound phenomenon in cold working of stainless steel pipe fittings with hydraulic press

Pressing oil compressor driven clamping fixture, along the slide downward pressing stainless steel pipe, to pay special attention to the tire pressure must be to achieve a closed position, pressure did not in the end, tube arc is not forming.

Pressure grading of cold pressed stainless steel pipe fittings

The pressing force of the cold pressed stainless steel pipe fittings can be drawn from the following conclusions:

Some deformation characteristics of large diameter high pressure stainless steel pipe fittings

Reasonable material size determines the role of steel in the process of pressing and deformation. Some deformation characteristics of large diameter high pressure stainless steel pipe fittings:

Control measures to prevent corrosion of outer wall and inner wall of stainless steel pipe fittings and components

(a) minimum requirements and procedures for the prevention of corrosion and corrosion on the outer wall and inner wall ofstainless steel pipe fittings and components, and is suitable for new pipeline projects and existing pipeline systems.

Surveying and mapping method for 180 degree stainless steel pipe fittings

180 degree stainless steel pipe fittings mapping method are as follows:
​

Outdoor water supply stainless steel pipe fittings should be paid attention to in the construction of the winter period is what matters

Outdoor water supply stainless steel pipe fittings, when the rain period construction should dig drainage groove, collecting well, ready to pump (submersible pump), pumping equipment such as rubber hose, so that the water pumping, should keep rain water bubble idler, avoid the accident of drift tube, after the completion of the construction should be timely backfill soil.

The installation of special stainless steel pipe fittings

From time to time in different special stainless steel pipe fittings installed will be the actual value compared with the theoretical value and pay attention to the deviation. Special stainless steel pipe fittings, for example, is generally can't adjust the size of the deviation, balance only by the installation of pipes. At the same time for the part of the pipe hanger and installation location, for example. Need to tilt the installation position to pay attention.

Assembling method of general stainless steel pipe fittings

General stainless steel pipe fittings assembly mode can be divided into roughly two categories: one kind is detachable, non-standard flange, thread and packing methods of connection. Another kind is not detachable type, important is connected by welding method. These two kinds of assembly way have different requirements in the installation.

The welding of stainless steel pipe fittings

The welding of stainless steel pipe fittings is a strong technical work. Only absolutely guarantee the quality of weld to ensure the safety of use.

Calculation of stainless steel pipe fittings materials by yaang.com

Calculation of stainless steel pipe fittings materials
Stainless steel pipe fittings are divided into many kinds, elbow, tee, sleeve, reducers, such as, and bearing in type, card type, butt type. Offer money to see what material and what process. , the formula of every enterprise divergent samples, and also more than a formula, strange size tee in price have can differ greatly, which is due to differences in component and process incurred.
The formula for calculating the actual weight of the stainless steel pipe per meter: w=0.02466 (D-S), the w refers to the actual weight per meter of stainless steel pipe fittings, D refers to the nominal diameter of stainless steel pipe fittings, s refers to the nominal wall thickness. Security refers to the premise and guarantee for honing standard rules now rules. The premise of guarantee needs in accordance with the standard rules and guarantee stop training, test results for the standard rules. The inspection will include the premise of chemical composition and mechanical function, size deviation, rough quality process function.

For passivation of stainless steel pipe fittings by yaang.com

About the passivation of the stainless steel pipe fittings
In our today's career stainless steel pipe fittings used to say very much, but you know that just get its hands on stainless steel pipe fittings is put into immediately to use oh, you know to forefathers sex passivation disposal? Any stainless steel parts, if no plating or other coating request, ordinary
At pre treatment (including pickling to black, polishing, etc.) through the passivation disposal, talents when products or disassembled into parts. Thermodynamics can be improved after passivation of stainless steel in medium volatility, prevention of stainless steel parts of the corruption, make stainless steel appearance has enough clean degree

How to process the inner thread of the stainless steel pipe fittings by yaang.com

Whether it is stainless steel welded pipe fittings or stainless steel seamless pipe fittings have internal thread, this kind of internal thread is how to process? In fact, the method is relatively simple, tap tapping can be done. Although the process is not complicated, but there are still a lot of places to pay attention to.
