Steinmans Safety Blind Manufacturing

At Steinmans, we specialize in the design and fabrication of standard and custom Safety Blinds for 100% safe isolation of piping and equipment. We manufacture blinds available in all different grades of metal including, stainless steel, carbon steel, Monel®, Inconel®, nickel alloys, Haselloy, chrome-molybdeum, aluminum, etc. Blinds are available in sizes ranging from 1/2 in. to 60 in. pipe size and for flange classes 150 lbs. to 2500 lbs.

All blind products are manufactured under a strict quality assurance program. Our team of engineers have improved and redesigned the standard paddle blind by incorporating additional safety features and design advantages. Our new safety blind designs are lighter and more cost effective than the standard paddle blind.

Welcome to Steinmans, LLC

At Steinmans, we specialize in the design and fabrication of safety line blinds - also known as safety spade blinds or safety slip blinds. Our manufacturing facilities have the capability to fabricate and test our safety blinds to customer specifications. Steinmans Safety Blinds are fabricated with a minimum thickness of 1/8" and are to be used in non-pressurized systems to block potential pipe flow. Our Safety Blinds are unlike standard Line Blinds or standard Paddle Blinds because they are fabricated to these minium thicknesses. All of our Safety Blinds are used for personal protection only and are marked with "Not For Pressure" one each and every blind.

The spade blind - also known as the line blind, paddle blind, skillet blind, spectacle blind, slip blank, or figure-8 blind - has been used for years as one of the most common ways to safely gain a temporary shutoff in a process piping system. The use of blanking spade blinds during line breaks and shutdowns has been a safety standard and procedure for major industries across the globe. Our innovative blanking safety spade blinds are unlike anything else currently on the market. Our team of engineers have improved and redesigned the standard spade blind / paddle blind by incorporating several added benefits and design advantages. View our Spade Blind Design Page to learn more.

Steinmans‘ blanking safety line blinds incorporate the functionality of a standard safety paddle blind while adding more safety and design features.

In the past, many of Steinmans‘ customers have special ordered line blinds with minimum thickness to be used as a simple yet essential safety device to block potential flow in a line during a shutdown or scheduled maintenance. Due to the volume of such special orders, Steinmans has redesigned the standard line blind - also known today as the paddle blind, slip blind, spectacle blind, figure 8 blind, pancake blind, or spade blind - to offer more safety features and benefits.

The following features of Steinmans' new blanking line blinds are listed in greater detail on our spade blind design page:

Steinmans‘ blanking safety line blinds are truly a one piece construction. They are precision cut and follow very strict dimensional and thickness tolerance requirements. Steinmans‘ line blinds feature a redesigned handle that affords more safety during installation, use, and removal through the addition of a "tagging hole" for attachment of a safety tag. A safety flange check guide has been added to all line blinds, as well as an "easy identification" section that allows users to quickly check material of construction, flange class, pressure ratings, etc. Steinmans‘ design introduces a special lock-out feature which allows line blinds to be locked-out when in use for longer durations. Steinmans‘ new design is also lighter and more cost effective than the standard paddle blind.

One of the most noticeable marking changes on our paddle blinds is the addition of the abbreviated flange class and pipe size text (inverted marking). This marking is being introduced for added ease of identification. At Steinmans, we wanted to give our customers an added benefit for using our blinds vs. the competition. Therefore, we designed this text to be much larger and bold so blinds in use can be identified at a distance. The text was also inverted to make it easier to identify during storage and non use.

We now include tagging holes as part of our standard spade blind handle design! Many of our customers have requested an additional "tagging hole" to be added to the handle of our spade blinds. This hole is used to attach a lock-out tag or identification tag to each line blind in use or on the shelf. The tagging hole sizes range from 1/4in. diameter to 1/2in. diameter (for the larger spade blinds). We have integrated the tagging holes into our standard spade blind design and will be included as part of our fabrication process unless noted otherwise by customer request.

Our blanking spade blinds are more efficient and cost effective than the competition and here's why:

Spade blind thickness are kept to a minimum resulting in lower material cost and total weight. Our standard safety paddle blind thickness is 1/8in. thick. No special machining / milling is required for the gasket surface, thus eliminating the cost completely. The standard finish for our spade blinds is a mill finish of typical SA516-70, SA-36, SA240-304, etc. Our spade blinds can be manufactured in just about any type of material. Therefore, they can be applied in virtually any type of process piping system in applications where there exists potential flow downstream. Our spade blinds are used to eliminate the potential environmental and physical hazards that occur from insufficient line blocking during a shutdown or scheduled maintenance. Our safety line blinds are lightweight and portable. They can easily be stored while not in use or transported from job site to job site.

Our engineers have completely re-designed the standard spade blind handle to be safer and easier to use. Today's spade blinds or line blinds are typcially fabricated with either a solid flat "skinny" handle or with a thin metal rod handle - which are sometimes difficult to work with and identify when in use. Our handles are designed to accept your standard 3/4" shackle to be used for rigging out of tight spaces. They also make it easier for transporting and hanging for storage when not in use.

Our blanking spade blinds are cut to precision. We follow very strict dimensional and thickness tolerance requirements, while others do not. Many companies try to save money by importing their blind disks from foreign manufacturers in China and Mexico, where quality standards are quite often not as high. All of our spade blinds are cut from domestic metals and 100% made in the USA. We take pride in our blinds and stand behind our quality.

Quite often line blinds or paddle blinds are left in the line for days, weeks, sometimes months, or even permanently. Our handle allows the customer to lock-out these blinds by simply placing a chain through the handle and around the pipe or valve. Then finally securing the chain ends with a lock or group lockout device. This provides an extra level of safety to the job and will ensure compliance with proper lock-out procedures.
