Reverse Formed Wedge Wire Pipe

Wedge wire filter pipe, also known as Johnson pipe, Johnson sieve pipe, stainless steel sieve pipe, is widely used in oil, gas, water wells and sand control in the world, and it is especially important in chemical and environmental protection industries. It is one of the most widely used filter sieve tubes used in various oil, water resources recycling and resin collection materials.

The wedge wire filter screen adopts the world's most advanced full-wound welding production process, and the special T-shaped wire is wound and welded on a group of support wires arranged in a circle. Full-process welding guarantees the strict and continuous integrity of the product, so that it forms the ideal gap size, and has the maximum capacity to withstand high pressure. Due to the use of full-program welding, not only the strict continuous integrity of the product is guaranteed, but also the ideal gap size is formed. Compared with the welding process currently widely used in China, the full-welded wedge-shaped wire winding screen has the characteristics of smooth pipe surface, no production edges, no burrs, and uniform gaps without leaking grease.


Details:

Material: stainless steel wedge wire or custom.

Surface profile: triangle wire.

Support profile: triangle wire, round bar, and wedge wire.

Slot size: 0.05 mm - 35 mm

Cylinder diameter: 10 mm - 1200 mm

Application: mine, coal, mineral and other application


Reverse formed wedge wire screen pipe (internal circumferential wire with external axial support rods) is a kind of strainers that flow from inside to outside filtration, with smooth working surface inside. This type wedge wire screen pipe is manufactured by wrapping and welding stainless steel V-shaped profile wire cylindrically around support rods under automatic specialized wedge wire screen machine, then be made to screen pipe through cutting, reverse rolled, welded processing.

For special areas of application (among others, the starch industry) screen cylinders can of course also be manufactured in looped finish. Adjoining is an example of two end flanges. In this case, as well, almost all requirements by our customers can be realized after corresponding technical clarification.

UBOW can offer reverse formed wedge wire screen pipe in the standard specifications, the slot size from 0.2 mm to 1 mm, while pipe diameter from 100 mm to 914 mm, and manufacture pipe length is up to 3 m, the wedge wire screen pipe is commonly constructed with materials of grade 304 (1.4301) stainless steel.

Wedge Wire Filter Tube/Pipe advantages:

1. The application of wedge wire on the filter element forms a V-shaped opening between the gaps of the screen tube. Due to the inherent advantages of the design, it can operate more efficiently than other types of filtration products, not only ensuring the smoothness of water resource filtration, but also the flow rate of the wedge wire filter pipe is three times that of the bridge filter pipe in terms of working efficiency. 9 times the slit water filter!

2. Structural advantages of wire winding. The arrangement of the longitudinal support rods according to actual needs and the form of the continuous gap of the screen tube make the product more

High compression resistance. The T-shaped wire and all longitudinal support rods are combined by electric welding, which is sturdy and durable, with a longer working life cycle and low comprehensive cost.

3. Large gap in the filter tube. Any sieve tube gap size with a gap between 0.02mm-60mm can be made according to actual needs to meet different application conditions.

4. The winding wire and all supporting wires are connected by electric welding, which is strong and durable, and the working life cycle is longer.

5. The longitudinal arrangement of the support wire and the form of the continuous gap of the screen tube according to the actual needs make the product have higher compression performance.

6. The advantages of this product have improved the working efficiency and service life of the well, making this product a leader in water filtration equipment.

Screen pipe connection:

Because the wedge-shaped filter tube is welded with metal wire, it can be connected by various connectors such as flange and electric welding. Wide application range and low comprehensive cost.


Remarks:

1. Fully welded wedge wire screen pipe can be customized with different specifications and raw materials (mainly stainless steel and carbon steel) to ensure reasonable investment and save production costs.

2. Sieve tube joints can also be made according to different needs.

3. Non-stainless steel products can be protected by galvanizing, and the appearance is beautiful and clean.

Who wins and who loses when oil prices fall?

A slump in oil prices is normally a cause for celebration in gas-guzzling nations. The average American burns through 10 litres of oil or oil products per day in normal times. But for oil producing countries - the "global petropolis" - such a drop in the cost of crude can spell disaster, and hardship for millions. It's easy to see why oil is referred to as black gold. When the price was riding high, oil revenues filled the coffers of companies and governments in the countries that produce it. That kept people fed and public services flourishing. But now, having oil can be a curse rather than a blessing. Oil price falls to 18-year low as turmoil persists Record deal to cut oil output ends price war The International Energy Agency previously warned that Ecuador, Nigeria and Iraq could be worst hit, with earnings falling by between 50% and 85% - and that was assuming oil prices of $30 a barrel. Now, it's less than $20 a barrel. All their economies were under

Wuhan declared free of Covid-19 as last patients leave hospital after months-long struggle against coronavirus

The city of Wuhan, the initial epicentre of the coronavirus pandemic, no longer has any Covid-19 patients in hospital after the last 12 were discharged on Sunday. Their release ended a four-month nightmare for the city, where the disease was first detected in December. The number of patients being treated for Covid-19, the disease caused by a new coronavirus, peaked on February 18 at 38,020 – nearly 10,000 of whom were in severe or critical condition. “With the joint efforts of Wuhan and the national medical aid given to Hubei province, all cases of Covid-19 in Wuhan were cleared as of April 26,” Mi Feng, a spokesman for the National Health Commission said on Sunday afternoon. The announcement came only one day after the city discharged the last patient who had been in a severe condition. That patient also was the last severe case in Hubei province. The last patient discharged from Wuhan Chest Hospital, a 77-year-old man surnamed Ding, twice tested negative for Sars-CoV-2, the

Filtration in the Food and Beverage Industries

The production of food and beverages is an important, although by no means the largest, component of the separation equipment market. A review of this sector must begin with a definition of its content, which, fortunately, is reasonably precise, involving little overlap with other sectors. The major anomaly lies in the production of drinking water, strictly the largest of the beverages, but in fact so large as to be in an end-use sector of its own, and therefore not included here. Minor classification problems would include the production of fermentation ethanol, as a fuel or as a beverage (or an industrial chemical), and the use of animal or vegetable fats and oils for industrial purposes. The actual coverage by this article of the specific end-use applications is then as given in the following list, in the order used in the UK Standard Industrial Classification: • Processing of meat, fish and their solid products (excluding oils and fats). • Processing of fruit and vegetables and the
