Stainless steel service pipe cleaning pipe installation ends proposal with 3% potassium permanganate disinfection sterilization, ban on choose such as bleach disinfection sterilization, and after the disinfection sterilization must use water to clean and tidy. If not delivered in the short term, so must must use compressed air to blow out the remaining water in the pipe, thus avoiding tube in anaerobic exercise reflect erosion and other substances.
Pipe racks installed stainless steel tube in the aerobic exercise aluminium coated tubes can resist 200 PPM of chlorine ion content in the natural environment, 2 PPM potassium permanganate etching. If carbon steel brace class structure, must solve, make pipe insulation to prevent rusting of the phase difference, and the outside world should cyst thermal insulation material, to carry out the rust. Remember good don't use chlorine ion with a halogen bulbs etc for stainless steel tube etching effect of super glue and other raw materials.
Brake disc shaft lever must and the center line of the pipe into the vertical placement, and must also put the convex ring pipe into the shaft lever concave groove in conformity. In order to better security protection practice, the operation staff only stand in the center of the pipe line, can't stand at the upper and lower sides of the tong head.
1, manual type press-fitting, special tools, shaft lever for around two piece of fixed control module, the working pressure is set to the output constant voltage 50 mpa, test standard for observation about shaft rod joint, the charging - one to a few times.
2, large and medium-sized electric conformity of special tools for 220 v motor drive hydraulic cylinder conformity of switch power supply connection hose and quick plug connector must be no dirt, or waste into the oil duct system software might harm normal application special tools. Join good server and hydraulic oil cylinder, open switch power supply first, then twist discharge pressure valve, until the barometer rose to 45 mpa, automatic jump pressure or server, then open the discharge pressure valve, close the program, for pressure stainless steel tube 304 relief namely take off discharge type pliers head completely.
Each end of the conformity of actual effect, must examine the viega profi-press forming can not happen conformity of unqualified or fitting the condition of the conformity of serious retraction. Estimates for the pipe port and fitting cater to compactness, DN25 above pipe forming ling side smaller diameter slightly smaller than the diameter of a pipe at 0.1 2 mm, tube the bigger the difference.
Precision steel tube is with stainless steel castings or wear-resisting rubber finishing made capillary tube by the broken hole, then the hot rolled, cold rolled steel and cold dial, precision steel tube in precision steel tube, a raw material, carbon steel, many of the production and processing company can choose, do die materials used.
Physical properties is to ensure that the stainless steel material performance parameters of the main indicators, it depends on the composition of the steel heat treatment and management system. In steel tube standard, according to the different using requirements, set rashin characteristics and compressive strength, plasticity index, there is a high and low temperature characteristics of customer requirements, etc.
Tensile strength. Sample in the whole process rashin, when pulled to go Cold Drawn Seamless Tubes all out, except to sample the original cross-sectional area, the stress field of individual income tax, known as the tensile strength. It shows that the metal composite materials under the action of applied professional ability to resist damage.
Ultimate strength. With a concession of metal composite material, the sample during the entire rashin force does not improve when still can again flexion and extension stress field, says the ultimate strength. If force caused by reducing, the stress difference between upper and lower strength limit. Break elongation. In tensile experiments, the sample after tensile elongation increase the length and the percentage of the original gauge length, known as the tensile strength.
Transverse section shrinkage. The tensile test, the sample after snap its reducing cross-sectional area of the reduction and the percentage of the original cross-sectional area, known as section shrinkage.
The compressive strength index. Metal composite material against hard objects on the surface of the sag of professional ability, known as the compressive strength. According to the test method and the main purpose is not the same, can be divided into the compressive strength and compressive strength of rockwell hardness, brinell hardness, shore hardness, compressive strength and high temperature compressive strength at high magnification microscope, etc.
